Technology of installation of metal-plastic pipes with their own hands

  • Fittings installation equipment:

    In principle, everything. Instead of pipe cut, you can use a saw blade with metal, but it will be necessary to make sections strictly perpendicular to the surface. If you trust your charming, take a carpentry stub.

    Procedure for training

    Sold metal-plastic pipes of a small diameter in the bays. Before mounting, cut a piece of the required length from the bay. At the same time, it is necessary to consider the length that comes to the fitting. That is, it is necessary to cut off a piece with a slight margin - in 1.2-1.5 cm.

    The edges of the segment are inspected if there are burgers (with a cutting pipe cut, it does not happen, this is a lack of cutting with a saw), they are aligned. Next, with the help of a trimmer or a piece of sandpaper, the chamfer is removed - the plastic is raised at the corner of both inside the pipe and outside.

    Cut, calibrate, remove the chamfer

    Cut, calibrate, remove the chamfer

    After that, they take a calibrator, with an effort driving it into the pipe and turning, align the geometry, at the same time straightening the "crushed" inside the edge. After that, you can start the installation of metal-plastic pipes and installing fittings.

    How to align a piece of metal-plastic pipe

    As already talked, this type of pipes goes to the bays, that is, they are twisted. Cutting off a piece, hand you stretch it a bit, but how to achieve perfect evenness. This is important if the mounting of the pipeline is open. The recipe is simple:

    After the segment becomes smooth, you can calibrate its edges.

    Installation of metalplastic pipes

    The installation of a pipeline from metal plastic includes several stages:

    • Preparation of materials, tools.
    • Installation of connections.
    • Testing the finished pipeline.

    Preparation of material for all types of compounds is the same. Pipes must be chop according to the project. When measuring, you should consider the appearance of lengths for fitting.

    Metal-polymeric

    Since metalplastic is sold in the bays, the material before installation it is necessary to straighten through the pipe on the smooth surface by rolling. Pre-pipe should be wrapped in several layers of the vehicle.

    Instruments

    A set of tools for mounting metal-plastic communications depends on which fittings are used to connect the parts of the pipeline.

    To assemble a pipeline from metal-polymer pipes, you must have:

    • Truboresis or hacksaw for metal cutting;
    • Calibrator - to expand the pipe and giving the circumference of the ideal proposition;
    • Fatheck repairman - for chamfering;
    • Entry paper for stripping burr at the edges of the pipe;
    • adjustable (or wrench) keys;
    • press clamps for some types of compounds;
    • Construction hairdryer or bending device, such as sand.

    Cutting is preferable to make scissors, but you can use a hacksaw or a sharp knife.

    Note! Due to the application of physical pressure on the pipe, the slice is obtained oval, there is burstages. To eliminate defects, you should use a calibrator, a chamimal or sandpaper.

    When the edges are prepared for the connection, the pipe is inserted into the fitting. There are several types of compounds of metal-plastic pipes among themselves or with the transition to another material:

    • compression fittings;
    • press connection;
    • Push-fit.

    Compression connection

    The combination of metal-plastic pipes with compression fittings is common and affordable for self-installation. Such nodes can be disassembled and collecting again. To install, you will need 2 digit keys.

    Compression connection

    Installation algorithm:

    • The fitting is spinning and disassembled. The cape nut and the crimping ring is put on the end of the pipe.
    • The inner part of the pipe and the end of the fitting with a rubber gasket is lubricated with thick soap foam to facilitate the combination process. With the same purpose, the inner diameter is previously bounded by a calibrator. Such measures will prevent the displacement of rubber gaskets.
    • The fitting is inserted into the connection site, shift the ring and twist the nut. The spinning process is carried out using two keys.

    Note! The nut should be tightened to the first appearance of the characteristic metal crackling of aluminum foil. If you stop before, the connection will leak. If you drag, the fitting will have to remove and discard, and cut the pipe again.

    The resulting connection requires periodic control and pulling nuts during leakage.

    Press connection

    The crimping connection is mounted using press fittings and press instruments (manual or electric).

    Press connection

    Installation scheme:

    • Preparation: Scroll processed and cleaned. The press fitting disassemble and check the integrity and availability of gaskets, then collected again ..
    • The edge for the connection is put on the fitting to the control window.
    • Crush the sleeve with press clamps, the instrument handles are reduced until it stops.
    • Repeat operations at the opposite end of the connecting fitting.

    The resulting connection can serve up to 50 years, but is intimidrate.

    Push Fit Connection

    Push fittings are the most expensive elements for connecting pipes from metal plastic. However, their use does not require any tool and skills, is reliable and durable.

    Push Fit Connection

    The prepared pipe is inserted into Push-fit to the control opening. Next collect the whole design. Start a test stream, under the action of which the connection is fixed by the inner wedge.

    Varieties of fittings

    When installing water pipes from metal plastic pipes, do not do without additional materials and tools.

    Tools that may be needed when working:

    • Truboresis or hacksaw for metal;
    • calibrator;
    • roulette;
    • spanners;
    • ticks or press (when using press fittings);

    From materials, first of all, fittings and clips should be purchased for fixing the pipe to the floor or wall.

    Fitting - This connecting part of the pipeline used during the installation of the water supply system is used for branching, transition to another diameter, and also serves to connect heterogeneous pipes. The appointment of fitting depends on its execution. If it is necessary to connect a metal-plastic pipe with a crane or metal pipe, the fitting of the CANGA-thread system is selected. If among themselves, then the Canga-Cangga system is used.

    In addition to the collet fittings, there are structures with crimping mechanism which fixes the metal-plastic pipe by the circular crimping pipe with special ticks or press. This option is more reliable, installation takes less time, but the cost of work increases significantly, first of all, due to the need to acquire a special tool.

    Conclusion

    Observing simple rules for the installation of metal-plastic pipes, you can independently pave both heating and water supply in your home. If you do it for the first time, do not rush, but especially gently perform the bends of pipes. Plastic locks are better attached to the wall before, and not after laying the pipe, it will be more convenient.

    Installation using collet fittings

    device

    The connection process takes very little time and consists of the following steps:

    1. If necessary , It is cut off a piece of pipe with special pipe cutter or hand-hacksaw for metal.
    2. A place where the separation was produced, aligned with the help of a calibrator
    3. The fitting must be disassembled. Then the fitting nut dress up on a carving pipe facing the edge of the pipe. The nut must be moved away from the edge by 20 - 30 mm.
    4. On the pipe It is put on the collet ring and also slightly moves from the edge.
    5. Fitting fitting It is introduced into the pipe until it stops, at the same time, care must be taken in order not to damage the rubber seals.
    6. Nut twisted.

    On the other hand, the fitting is connected to a threaded compound with a crane or metal pipe, or if it is a Canga-Tsang system, then with a metal-plastic pipe. The fitting may also have a tee shape for branching in the system. If the tee is used to branch from the main line to the crane, the tee can be applied: 20 * 16 * 20.

    Installing crimp (press or push) Fittings on MP pipes

    Installation of metal-plastic pipes using crimp fittings requires special ticks. They are manual, there is electric. Any is equipped with a set of linings for different diameters. Manual, naturally, cost cheaper. This equipment is not necessary to buy - it will be needed only once. Much more profitable to rent.

    Press fitting for MP pipes

    Press fitting for MP pipes

    A press fitting of two parts is the actual housing and crimping sleeve. Before connecting metal-plastic pipes, carry out a cut preparation. It is the same as when using compression fittings, but the chamfer is removed only from the inside. Next, the procedure for such:

    • Sleepers put on the pipe.
    • The fitting establishes the gasket to prevent electrochemical corrosion.
    • Tuba is put on the fitting - until it stops. On the fitting housing there is a hole in which the edge of the pipe should be seen.
    • Take ticks in which suitable lining (the desired diameter) are installed. Pliers are installed close to the edge of the fitting, connecting the pen handle together crimp the item. As a result, two concave bands should be clearly visible on the sleeve. Their depth should be the same. After crimping fittings can rotate around the pipe.

    On this, the installation of metal-plastic pipes using the press fitting is complete. A similar junction withstands pressure up to 10 atm, which is enough for most systems. Not suitable for home heating systems with floors. More than 16. They have pressure in the system may be greater.

    How to generate a metal-plastic pipe?

    The advantage of metal-plastic pipes, among other things, is the ability to bend them in the right place. It helps reduce the number of fittings used. This feature is used if necessary to make a turn and arrangement of warm floors. Bend the metal-plastic tube can be 4 ways:

    • hands;
    • spring;
    • using a hair dryer;
    • Pipe bend.

    Option # 1 - Pipe bending hands

    This method requires clever hand. To learn how to bend the pipe without any devices, watch the video instruction:

    Option # 2 - Spring will help avoid defects

    There is a spring on sale, specially intended for flexing pipes. It is inserted inside the product. After that, the bending is made easily and without defects. The size of the spring is selected under the size of the pipes.

    Flexing of metalplastic pipes

    The use of a spring for flexing metal-plastic pipes helps to avoid defects and damage to the product. Size of the spring must match the size of the pipe

    Option # 3 - Using a construction dryer

    Metal-plastic pipes under the influence of heat become more appropriate. To heat them use a construction hairdryer. Just do it you need carefully, so as not to overheat plastic. After heating, the pipe is bent into one movement.

    Option # 4 - pipe bender for the master

    And yet, if you are a novice master without work experience, it is better to use special pipe bender. It will help without much effort to bend the metal-plastic pipe of any size. There is a pipe bender-crossbow. To use it, it is enough to set the bend angle, insert the pipe and bring the handles.

    Flexing of metal-plastic pipes using a pipe-bender-crossbow

    If you do not have experience with metal-plastic pipes, it is better to use pipe bender. Special pipe bender-crossbow helps to bend the pipe under the right angle

    It is clear that without effort to make high-quality water supply or heating will not work. To any work that you will perform with metal-plastic pipes, from the selection of the product before checking the system's capacity requires responsibly. Only in this case can be guaranteed the durability of a plumbing or heating line.

    How to fix the walls of pipes from metal plastic?

    To secure the pipeline from metal-polymer, there are special plastic clips or brackets. Choose fasteners on the diameter of the pipe. Fasten to the walls in the place of laying of communications.

    Clamp and Clips

    The distance between the mounts is 1 meter. At the same time, in places of bending attachments are performed on both sides.

    Blitz advice

    Installed metal-plastic pipes

    1. Mounting work You can spend yourself independently, the main thing is not to hurry, and if you need to make any action for the first time, for example, bending, it is better to first work on some unnecessary segment of the material.
    2. All work must be carried out Only when the water supply is disabled from the riser.
    3. Do not be afraid to use when carrying out repair work Modern materials. Plastic, which is used in building materials, if not heated above certain temperatures, does not emit harmful substances. Of course, this is true only about certified products purchased in specialized outlets.

    Example Water supply system

    First, draw a water supply layout plan. You can do it on a sheet of paper, denoting the necessary fittings. Please note that the installation of the cranes requires a carving fitting at the end. Cranes are needed on the discharges to household appliances and to plumbing devices, to heating radiators. This makes it possible to turn off the devices without overlapping the entire system entirely. Type of thread and select it depending on the type of crane used.

    An example of water supply system on metal-plastic pipes

    An example of water supply system on metal-plastic pipes

    Also, adapter fittings are needed before and after the meter (water or heating depends on the type of system). Drawing a detailed plan, put sizes in all areas. For this drawing, you think how much and what you need. Fittings can be purchased strictly on the list, and the pipes are preferably taken with some reserve. First, you could be mistaken when measured, secondly, in the absence of experience, you can spoil some piece - cut down less than it is necessary or improved, etc.

    Agree on the possibility of exchanging

    When buying everything you need to agree with the seller that, if necessary, you can change / return some fittings. Even professionals are often mistaken with them, and one who decided to make a wiring of the water supply system or heating from metal plastic with their own hands and is suppressed. Nobody will accept the remnants of the pipe, and fittings are easily. But for the guarantee, save the check.

    Sometimes it is convenient to use collectors. They allow you to connect several consumers in parallel. There are collectors for water supply and heating (with a warm floor laying)

    When and how to start work

    Having come home, spread the fittings, proceed: the installation of metal-plastic pipes in the summer can be done immediately, in the winter it is necessary to wait for a while (clock 12), until all the elements are warm to room temperature. Cut with just one segment of the pipe of the desired length. This is a little longer, but they definitely not confuse. Further actions depending on the type of fittings selected.

    Wiring heating with metal-plastic pipes is made only on press fittings

    Wiring heating with metal-plastic pipes is made only on press fittings

    After the installation of metal-plastic pipes is completed, the pipeline is checked. If it is a plumbing, just open the tap at the entrance. It is necessary to do it gradually and smoothly. The system will immediately begin to fill with water. If nothing else flowed - you did everything right. If some connections flowed, they need to be altered - if press fittings were used, or tighten - if the assembly was on crimping connectors.

    If the heating system was assembled from metal-plastic pipes, before starting it, it should be placed - to experience with high pressure by posting cold water into the system. If the test has passed successfully, you can make a trial launch of heating.

    Installation of metal-plastic pipes with compression fittings

    Compression fittings consist of several parts. The base is cast carbon case. There is also a crimp ring that fixes a piece of pipe on the fitting and a cape nut that clamps the connection. An important detail is a sealing ring that provides tightness.

    This method of installation is good because there is no special equipment. The second plus is the collapsible connection and, if necessary, can be replaced fitting. If he failed or has the need to change the pipeline configuration. And it is very convenient.

    But there is a disadvantage: from time to time on a thread occurs. It is eliminated by everything simply - tightening to the half-turn. But because of this, all connections should be accessible and aligning them. Also strains the need to check - flowed, not flowed. Not everyone likes it.

    So the compression fittings look like
    So the compression fittings look like

    Assortment of fittings is a wide corner, tees, crossmen, adapters (from one diameter to another). And all this with different angles, in different diameters.

    Installation of metal-plastic pipes on compression fittings begins with the fact that the cape nut and the crimping ring is removed, the presence of a sealing gum is checked. After that, the assembly itself begins:

    • Nut and ring wear on the pipe.
    • The segment is stretched to fitting until it stops. The emphasis is indicated by a special small border protrusion.
    • The ring is tensioning too until the fitting stops.

      Before tightening the naika
      Before tightening the naika

    • A tight nut is tightened. First with hands, the connection of metal-plastic tube pulls up with two keys. One holds the fitting body, the second turns the cape nut.

    On this, everything, the process of installation of compression (screw, threaded) fitting is completed. There is only one nuance: if you pour antifreeze into the system, change the gasket immediately. Those that come in the kit will flow with non-freezers very quickly. Place paronit or teflon. Only they can provide tightness. In general, for systems with antifreeze it is better to use press fittings. They definitely do not flow (if they are properly compressed).

    How to bend a metal-plastic pipe

    Often the installation of metal-plastic pipes occurs the need to bend the pipe. You can do it with your hands or with a spring. It's easier and faster to work with a spring, but it must be bought (it is inexpensive). The spring is inserted into the pipe and bends in the desired direction. The pipe repeats the bending, the spring is removed. Bending metal-plastic pipes with a spring are simple - no more effort required, the actions are easily controlled, it is possible to adjust the result.

    What is good this way - you will not be able to overcertrine the walls, which happens when an excessive force is applied in the manual method. Also, it is not possible to make a sharper bend (with a radius less than the minimum) and squeeze the walls on the bend, catching the passage section.

    Hands of bending MP pipes must be gradually. Take your hands from two sides from the place of bend (at the same distance from the center of the future arc), the thumbnails are backing the pipe. In this position, start the edge to lower down, at the same time pulling the top fingers upstairs.

    With this method, sometimes from excessive force, the pipe loses its geometry. This negatively affects its bandwidth. It is impossible to put such sections in plumbing or heating. To avoid such situations, the scene is heated. This can be done only with the help of a construction dryer. It is impossible to use open fire. Preheated plastic bend simply. At the same time, it is not silent (the main thing is not to overdo it).

    Another way to avoid deformation is to pour into the sand. It will not give the walls to shrink.

    How to fix the walls

    With the opening of the pipeline, it is required to somehow fix on the walls. Typically, special plastic clips are used for this. They are single - for laying one piping thread. Usually used when laying the water supply. There are dual - most often they are installed on heating - the supply and return in the two-pipe systems are in parallel.

    Clips for mounting metal-plastic pipes on the wall

    These clips are installed through each meter (more often). The hole is drilled in the wall in the wall, the dowel of the required type is inserted (it is selected depending on the type of material from which the walls are made). Large load is not foreseen, but a water supply and heating looks much more attractive if everything is lured exactly as Lineshek.

    Non-standard connections: with metal pipes, transition to another diameter

    When replacing the water supply or heating, it is often necessary to connect metal and metal-plastic. Most often it happens on a tap from the riser. In this case, the metal tube is cut at some distance - 3-5 cm, thread is cut on it. Next, the thread is screwed down with a feather nut (Cangua) or internal thread. Next, the installation of metal-plastic pipes is on ordinary technology.

    Some types of fittings that can be used when moving from metal to metalloplastics
    Some types of fittings that can be used when moving from metal to metal plastic

    The fitting is selected on the diameter of the metal pipe, and the thread on the adapter must be internal - the outer is cut on the pipe. This connection requires a seal. Complete with flax and mold packing paste or simply use fum-tape.

    The connection of two pipes of different diameters occurs just as well. Only the appropriate fitting adapter with nuts / nipples of a suitable diameter is required.

    Example Water supply system

    First, draw a water supply layout plan. You can do it on a sheet of paper, denoting the necessary fittings. Please note that the installation of the cranes requires a carving fitting at the end.

        • Spanners: Original and horned. Used to twist nuts in compression fittings.

    Scissors for cutting

        • Scissors for cutting pipes. Without their use, it is much hampered by cutting material on the desired segments with smooth edges.

    sandpaper

        • Grinding paper Need to stripping cuts from small roughness.

    Calibrator

        • Calibrator. With its help, the cut is returned to the initial roundness, lost in the process of cutting.

    Press concrete

        • Press Required for manual compression of press fittings.

    Construction Fen

        • Construction Fen It is used to warm up pipes before bending.

    Installation technology. Installation instructions

    Compression fittings

    Compression fitting

    Installation of compression fittings

    • The fitting is spinning: From the ends remove the mounting nuts, from the fittings - sealing rings.
    • The pipe must be straightened and cut into scissors. Use other cutting tools is not recommended: the slice is irregular, it is possible to violate the integrity of the protective layer of the material.
    • Slices need to be carefully cleaned and calibrated. Poor treated ends can damage the sealing rings and disrupt the tightness of the connection.
    • At the prepared segment, a cape nut with a sealing ring is put on. Fitting fitting is connected to the pipe and fix the nut: first manually, and then with a wrench.

    Control compression! Hearing the characteristic crackling of the metal - stop the process. It is important to comply with the balance: poorly tightened fitting will not be able to ensure the tightness of the system, and the pulled - you can immediately throw away.

    Press fitting

    Trimming

    • As in the first case, the pipe is pre-prepared: clipped, cleaned and calibrated. Pay attention to the end: it should be perpendicular to the central axis of the waterway.

    Stripping

    • After removing the sleeve, check the rings and gaskets, and then we make a fitting assembly. This is done in order to exclude the possibility of mounting the defective elements.

    Calibration

    • A plug of pipe is satisfied with the press fitting fitting. The depth of planting is monitored visually (through a special hole on the sleeve).

    Installing a press fitting

    • From the opposite end of the fitting, the process of nozzle is carried out in the same way.

    Pressing

    • With the help of press ticks We carry out the press of the connecting sleeve inside the fitting.

    The mounting process will pass faster and more successful if you buy fittings and pipes of one manufacturer.

    Push-fitting

    Installation and assembly Push fitting

    • For the connection, additional tools and devices are required.
    • It is necessary to check whether the shoe is tightened until it stops.
    • Prepared in advance cut pipes are simply inserted into the fitting hole.

    To reuse Push-fitting, it is necessary to disassemble the design. To do this, you need to promote the holding block and withdraw the pipe. A plate spring must be replaced with a new one - now the fitting is ready to use again.

    Clips for mounting to the wall

    Fastening to the walls of the collected sites is carried out using special clips or brackets that need to be selected based on the product diameter.

    How to bend metalplastic pipes

    Bend the metal-polymer pipe can be manually. In this case, there are small subtleties that it is worth knowing: the bend process must be carried out gradually (in several stages) and with the help of a construction dryer.

    It is necessary to heat the pipe with a hairdryer. Cook your hands so that the thumbs of the hands were along the pipe and served as a kind of emphasis. Slowly and gradually begin the flexing process in several approaches, if necessary, heated the product with a hairdryer.

    Do not make sharp movements! It is important to maintain the integrity of the inner layer and not deform external. At the time of folding, do not forget about the permissible bend radius, which is listed in the section "Technical Specifications". For training skills, use small trimming.

    Installation of metal-plastic pipes for water pipes with their own hands
    Installation of metal-plastic pipes for water pipes with their own hands

    Installation of pipes from metalplastic does not represent difficulties even for non-professionals. It is not necessary to be a plumber to make pipes for water supply with your own hands: it is quite thoughtfully familiar with the rules of the gasket.

    Choosing an option to install a metal-plastic system

    If you firmly solved the installation and wiring of metal-plastic pipes with your own hands, decide in advance with the option of laying the pipeline. It happens:

    • hidden (system "hidden" in the wall);
    • open (it passes along its surface);
    • Combined (combining both options).

    The desired method is selected taking into account:

    • Purpose of the room;
    • need to have access to the design.

    Fastening on the walls of metal-plastic pipes is carried out with the help of special clips. For the water supply, single, dual (for two-pipe systems) is usually used for heating. Choose them, taking into account the diameter of the product and fastened to the wall of dowels or self-drawing.

    So that the pipeline does not resist, the distance between the mounts is 1 m and less. To install heating, a step of no more than 0.5 m is recommended (so as not to disturb the circulation of the coolant). The bends are fixed on both sides.

    Hidden

    This is an aesthetic, but time-consuming option, commonly used in the bathrooms, as well as indoors, where it is possible to damage the surface of the structure. To hide it inside the walls, the channels are strokes, lay the system and close the excavations with finishing materials, leaving access to fittings (using the "windows" or removable panels).

    Hidden gasket it is impractical to use:

    • for bearing walls (they are forbidden to stroke);
    • In the already finished room (you have to dismantle, and then restore the wall cover).

    The main plus is the view of the pipeline does not spoil the design of the room.

    Open

    Open wiring should not be done if:

    • There is a possibility of mechanical damage to the surface of the structure;
    • They have access to ultraviolet rays (it is harmful to them).

    Pluses of the method:

    • Connection locations are visible - it is easy to promote to clean or replace a fragment;
    • Damage is not damaged (you can lay in rooms where the repair has already been made).

    Fastening with clips to the wall should be done as smaller, remembering that the pipeline is visible: the oblique lines of the eyes are not happy.

    Combined

    The pipeline is paved over the surface of unformed walls and is closed by special false panels or mounted boxes. The method requires an accurate idea of ​​the future design of the premises: boxes and panels should not disappoint the view of the room, but to organically fit into the design.

    Design and markup for material calculation

    Installation of metal-plastic pipes for water pipes with their own hands

    Working with any metal-plastic pipes (for water supply or heating) should begin with the development of their placement scheme:

    • Apply the lines of the future laying right on the walls - the visualization simplifies an understanding where it will be.
    • "Start point" is a connection location to the already installed crane or radiator.
    • Try to do as a smaller number of fittings (than them are less - the more stable water pressure).
    • If you need an angular gasket, decide: bending or use angular fittings.
    • Back at the markup stage, remember: all connections should be access. It is also necessary to tighten the fastens in case of need.
    • All connecting elements are installed after the markup and calculations are completed.
    • According to the circuit, the length of the pipeline is counted, the number of fittings and fasteners is calculated.

    Choosing a pipe for mounting

    The smallest requirements are presented to products intended for cold water supply. As for hot, it is necessary to take the goods with the PEX polyethylene labeling (stitched) and PE-RT (linear). Before purchasing, specify which indicators of the usual and maximum pressure from your water supply.

    Watch the certificate - whether the goods meet with hygienic requirements, appreciate the appearance on the subject of dents, scratches, other defects.

    Water pipe system

    For home water pipes, pipes 16 and 20 mm are most often used in diameter. If the main layout is assembled from 20 mm, then the windows to mixers, household appliances, and the bath make from 16 mm.

    Heating system

    Choosing products for creating a heating structure, consider the availability of quality certificates. Products should be calculated for the operating pressure of 6.6 atm and the temperature of 95 ° C and are not made from low pressure polyethylene: it does not differ in neither strength or heat resistance. Do not acquire products with re-RS marking, they are missing if the temperature of the coolant exceeds 75 ° C!

    Selection of fitting for docking pipes

    When the plumbing from metalplastic pipes is mounted with their own hands, you need to pay serious attention to the selection of fittings: the responsibility for leaks falls on you! Fittings are considered a "weak place", do not save on cheap options.

    Installation of metal-plastic pipes for water pipes with their own hands

    Compression fittings are simple, but less reliable than press fittings. Note that the hidden gasket implies the use of exclusively press fittings. In other cases, be sure to ensure the possibility of free access to compression.

    Preparation of instruments and consumables

    For installation of the design, a small set of tools will be required (all of them must be at hand):

    • Truboresis or sharp scissors (for hermetic compound it is necessary to strictly perpendicularly);
    • Calibrator (needed to center the cutting area and chamfering);
    • Sliding and horn keys (they spin nuts in compression fittings)
    • press clamps (by hand manually crimped press fittings);
    • Pipe bender (allow changing the configuration of the segments of the pipeline, without using the angular fittings - it is better to use it if there are many angular conjugations).

    Necessary materials:

    • actually bay, the measuring segments of the desired length will be cut off;
    • Different options for fittings (tees, bypass, angular) for wiring and creating a single design;
    • Elements of fasteners (clamps and clips from the manufacturer) for fixing the pipeline sections on support surfaces.

    Laying pipes from metalplastic

    As competently mount the metal-plastic pipe:

    • cut off the fragment of the required length;
    • By calibrator, adjust the cut shape;
    • Remove the chamfer from both surfaces - outside and inside - at the same time;
    • promotion fitting (remove nuts from the ends, sealing rings with fittings);
    • If the compression fitting is to wear a nut with a seal ring on a prepared fragment with a seal ring, connect the pipe and a fitting, fix the connection with the nut - spin it first, then use the wrench;
    • If a press fitting is used - first disassemble it and make sure: not defective (remember that it will not be promoting it "), then put it on the fitting prepared fragment, assess the landing depth - for this there is a hole on the sleeve. Then take advantage of the press clamp - to carry out the press of the connective sleeve twice, forming two ring compression.

    To form the desired bend, you can use the pipe bend or bend it with your own hands, heating with it with a construction hairdryer: in several techniques, without making sharp movements and remembering the allowable bend radius (specified in TX). The thumbnails of both hands are located at the same time along the product. Internal and outer layers of the product should not be deformed!

    To simplify the workflow, you can first collect individual parts of the system. Then the parts of the design are installed in the appropriate places and connect. Fixing each pipe to the wall is carried out using suspended and reference elements from the manufacturer. Installation of metal parts is made with gaskets made of special soft materials. After a consistent combination of all parts to attach them to "hot" and "cold" risers.

    Covering system of the water pipeline

    When the installation of water pipes from metal-plastic pipes is completed, it is necessary to check it for leaks using the crimping process:

    • It is necessary to overlap the test area filled with water for its sealing (using cranes / valves).
    • Connect to the connections of one of the cranes of the pump (for the home water supply system, a manual, low-power) is suitable.
    • Using the pressure test pump, download the water under pressure in the selected section of the water under pressure than the calculated work, then turn off the pump, fix the testimony of the pressure gauge.
    • The system is withstanding under pressure for some time - no less than half an hour.
    • Then compare the current testimony of the pressure gauge with the initial value. If two values ​​are different - something went wrong, there is a leakage.

    If you have an open gasket, the problem area will be able to detect visually. After eliminating the malfunction will have to re-conduct crimping.

    Metal plastic pipes

    Water pipes made of metal-plastic pipes - the most common option of the "wiring" of the water supply in houses and apartments. They firmly reigned in this market segment. And there is good reasons for this.

    On this page, we describe all the pros and cons of such a water supply, as well as in detail, we describe how to make metal-plastic pipes, how to connect them with fittings, etc.

    Advantages and disadvantages of metal-plastic water supply

    There are several objective indicators that allow metal-plastic pipes to shut up for the belt of their competitors when the water supply system in an apartment or house:

    1. Easy installation. With careful work, they can be performed by any person without any preparation. Almost this semblance of a designer, for the assembly of which expensive tools and special skills are not needed.
    2. Reliability. Warranty 50 years ago confirmation. But note that it applies to pipes, and not on their compounds.
    3. Price. One can say one thing: "Cheaper, just for nothing." Some competition for this parameter can be polypropylene pipes, but otherwise they lose.

    Based on the foregoing, the plumbing on metal-plastic pipes is obtained reliable, it costs it inexpensively, and you can collect it with your own hands. Naturally, connecting to the central system, it is the prerogative of professionals.

    No matter how regrettable, but Each honey barrel, there is a spoon of tar . In the case of metal-plastic water supply, these are fittings.

    Fitting, this is a device with which you can:

    In our case, we are talking about metal-plastic pipes. If the fitting at both ends has the same diameter, then it is straight; And if different, then transition.

    But these are only their varieties for their intended purpose, but according to the method of fixation, all fittings are divided into crimping and presses.

    1. Crimp fittings. Differently called ring, or served. In those, the fixation is performed due to the conical shape, the inner surface, the crimp nut, which, when twisting, compresses the edge ring. Such compounds can be disassembled and they require periodic maintenance. Usually once a year, crimp fittings on metal-plastic pipes for which flows hot water , It should be checked and, if necessary, tighten a little. The reason for their weakening is the temperature deformation from hot water. For their installation, two gas (adjustable) keys are required.
    2. Press fittings. Or non-maintained, fixed on a pipe by pressing a special crimping sleeve. Work is made by press clamp. They can be manual or electric. In the first cost from 4 TR, the second from 25 tr. The compound is obtained indefinitive, but with a guarantee from leaks, regardless of water temperature. Most often, press fittings are used in connections that will be molded into the walls, or with difficult access after repair.

    Reliability and quality of compounds depend on the scrupulousness of the execution of instructions. But at the price ... Although the press fittings are cheaper than the crimp, but their total cost for the water supply equipment in the apartment is equal to the costs of metal-plastic pipes.

    We plan a water pipe "on paper"

    The most important and primary, this is a plan of water supply layout. If you have never been engaged in this, then you can make it up with a clean leaf without much difficulties, although this is satisfied with the painstaking. But everything starts from the consumer.

    1. It is necessary to mark the places in which the cranes will be. This is a kitchen and a bathroom. With competent construction, they are usually located nearby, which facilitates and significantly reduces the cost of the water supply system. In the perfect version, if they are in adjoint premises, only one pipe will be required, from which the tee will be taken offen in different rooms.
    2. The place of arrival in the house of water is designated. There are only two options: central water supply or private well (well). Depending on this, additional equipment may be required. In particular, when using water from the well, it is necessary to install a hydroaccumulator (above the level of consumers). From it, water is self-shot to enter the house. Such a system is preferable, for it does not require constant inclusion of the pump. The hydroaccumulator does not have to be metallic. It can be "pouring out" from concrete. And already in the house mounted:
    3. Filter system (equipment depending on water quality).
    4. Boiler.

    Accordingly, that if the water flows into the house from the central water supply system, then the input will require only controlling instruments to account for consumption.

    This is a schematic diagram. Give recommendations on the filtration system, not knowing the quality of water, is not permissible. Also belong to the water heating system. Depending on the conditions, the boiler can be electric or gas. The use of a water heater on liquid or hard fuel is not economical and associated with certain difficulties. Especially in the summer.

    Required tools and materials

    Calculate the metro station of metalplastic pipe and the number of fittings. The easiest way to do it with the help of a bemp and several self-tapping screws (carnations).

    From the cranes, the bempwint is unwound along the wall. In places of bend or branching, cloves are clogged, and the direction changes. Accordingly, that from tees, two (or three) bemps will already go. By placing the entire system thus, it is necessary to draw its location not the wall. Can be chalk or water-emulsion.

    Only after that, the beep must be removed, and to measure its length. Additionally calculate the number of fittings and their types.

    Important: The resulting Pipe Metrah, increase by 10%. This is common practice.

    Regarding the selection of the diameter of the pipe, there are already a prevailing opinion. Almost for all residential buildings and apartments, with an excessive enough metal-plastic pipes ᴓ16 mm. It provides a flow of up to 3 m 3 / hour. And most water counters are not designed for greater flow. Yes, and why more?

    The choice of the manufacturer of metal plastic pipe is perhaps the most difficult task. In the market often come across fakes. Purchase a pipe in a solid store or from proven suppliers. We recommend to refrain from the purchase of metal-plastic pipes of Chinese manufacturers. Negative reviews are found too often. The highest quality metal-plastic pipes are produced in Belgium ( Henco. ), Germany ( Frankische and Sanha. ).

    What will be required of the tools:

    • Cutter for metal-plastic pipe (from 250 p).
    • Caliber with zenker (from 200 p).
    • Conductor (from 500 p).
    • Press ticks (from 4000 r., But you can rent).
    • Two gas (or adjustable) keys.
    • A hammer.
    • Sculpture.

    How to work with a tool

    Caliber, restores the shape of the pipe after cutting, and Zenker removes the chamfer and removes burrs. If the caliber is without a zenker, then its work can be performed using shallow sandwich.

    The conductor serves to flexing the metal-plastic pipe. It is external and inner. The use of internal in some cases is more convenient, for it does not slide in his hands. But it is not always possible, for the place of bending can be far from the end of the pipe. Therefore, we recommend to stay at the external conductor.

    Press pliers will be required if you use maintenance-free fittings. We, on the basis of 16 years of experience, we recommend that the press fittings are recommended. And the reason here is one. Most tenants, in a year they forget about the service of crimp fittings. And this leads to leaks. But the choice is yours.

    Consumables will require: self-tapping screws, fastening for metal-plastic pipes, tape FUM.

    Mounting process of metal-plastic pipes

    Starting the installation of metal plastic water supply is necessary from the source to the consumer (to the cranes). Make a cut from the roll to the nearest fitting, and cut it with a knife. Calibrate, remove the burrs and remove the chamfer. Then insert the pipe into the fitting until it stops. The press fittings have special holes, to control the depth. They should be visible the edge of the metal-plastic pipe. Then insert the fitting into the ticks, and crimp the connection.

    Crimp fittings are fastened with nuts and rings included in the kit

    It is quite simple to work with the press ticks, because insert the fitting "Crooked" will not work.

    All press clamps have replaceable sponges for pipes of different diameters. Do not make mistakes in choosing sponges.

    The process of installation of crimp fittings is slightly different. The nut first puts on the prepared trim, then the edged ring and after that, the pipe is inserted into the body of the fitting itself. Before spinning the nut We strongly recommend that turning the fum ribbon. It takes only two or three turns. It is necessary to start from the edge of the thread and carry out the winding, holding the latitude tape. After that, moisten the thread with sunflower oil. This technique will protect against the appearance of leaks!

    The nut is first twisted with their hands until it stops. And only then, holding the fitting with one gas key, others tighten the clamping nut. It should not be drawn out of all the might, but the small effort is necessary.

    Installation with press ticks

    Fix the metal plastic pipe to the wall follows each meter. Special attachments through the self-sufficiency are strengthened in the surface, and the pipe is inserted into them.

    In those places where it is permissible, the pipe can be bent using a conductor. To do this, the conductor dresses onto the pipe, supply it from the right place, and neatly, holding the product with his hands, on an equidistant from the target distance, bend the pipe in the desired plane. Given that the radius of the bending of the metal-plastic pipe is equal to its 8 diameters, this approach is not expedient everywhere.

    Checking, leakage

    By installing metal-plastic pipes, connect them to the crane with the help of hoses that are included. Then go through all the route again, and visually check the integrity of the assembly.

    Pay attention to tees and splitters. Sometimes, inserted by one branch, the installer forgets about fixing the pipe in another.

    Open the taps at the end of the water pipeline (in the kitchen and in the bathroom). And only after that slowly, in order to avoid a possible hydrate, open the water supply faucet to the system. It is most convenient to perform this stage with a partner. It should control the water outlet in the final point. As soon as the water went, for washing pipes, let it drag it within 2-3 minutes. Then close the outlet cranes, by this you raise the pressure in the system, and go through the pipe of the pipe gasket. Check all connections. If you doubt, do a paper napkin (or toilet paper) on the surface of the fitting connections). Do not confuse condensate with leak!

    We guarantee that if you fulfilled work according to our recommendations, then in 99.9% there will be no leaks. If a connection causes you a reasonable fear, then slightly tighten it.

    How to make the installation of metal-plastic pipes with their own hands

    In the life of a modern person, an important place is occupied by the transfer of various substances, in particular, water, by the distance using the supply systems - pipelines, the most important and extended part of which are pipes.

    Due to the wide range of products today, each host host has the opportunity to independently assemble the water supply system using products from any suitable material. This article will tell about the installation of metal-plastic pipes for water supply with their own hands, characteristics and advantages of such products.

    The device of pipes from metal plastic and their advantages

    Products of this type consist of three main layers and two sucks, from the inside to outward:

    1. The layer of molecularly compacted or cross-linked polyethylene.
    2. Glue layer between the inner layer and aluminum foil.
    3. Aluminum layer.
    4. The glue layer connecting aluminum and the outer layer of the polymer substance.
    5. Outer plastic layer.

    Advantages of products from this material:

    • relatively small, compared with metal elements, weight that makes it greatly facilitating all operations for maintenance, planned or unscheduled repair, dismantling and installing metal-plastic pipes;
    • Lack of corrosion threats, since the inner and outer layers of products are made of plastic not destroyed under the influence of water;
    • Thanks to the reinforcement of aluminum, the linear expansion coefficient is very low;
    • The consequence of the previous point is the ability to do not withstand the ideal accuracy during the calculations and preparation of products.

    Among the shortcomings of metal-plastic pipes, the following can be distinguished;

    • Their mechanical strength and resistance to overloads is still less than that of metal elements;
    • The upper thresholds of operating temperatures and pressure are also not so high.

    A few words about the wiring of the water supply system

    Wiring of metal-plastic pipes with their own hands as a whole is simple; The process begins with mounting on rising ball valves. At this stage, it is necessary to especially carefully select fittings, giving preference to high-quality products suitable for use at least 60 atm. and temperatures about 150 ° C.

    It is clear that, since, for the quality of Chinese products, no one can vouch for and bring it at any time, it is best to avoid acquiring it, stopping on more expensive, but reliable versions.

    Especially this is essential, if we consider that it is precisely through the ball cranes in the event of a leakage of the system overlap the flow of water into the apartment.

    Selecting good cranes and installing them, you can continue to mount the plumbing from metal-plastic pipes with your own hands.

    The following preparatory stages of water supply system arranged:

    1. Installing a filter for deep cleaning and watercolor.
    2. Installation of a filter intended for fine cleaning.
    3. Introduction to a pressure reducer circuit.
    4. Installation of the collector, from which the metal pipes will be discharged, connectable by various methods and subsequently connected to the instruments of the plumbing destination.

    Despite the fact that the inner surface of stitched polyethylene is sufficiently resistant to the effects of small abrasive particles, the installation into the system with metal-plastic pipe filters is necessary: ​​a large amount of sand, metal particles or pieces of scale can damage not only the pipeline, but also output devices.

    The collector must be assembled to provide the same intensity to supply moisture from a common riser to all sanitary cells - sinks, washing machine and toilet bowl.

    Usually in the collector is provided from two to four outputs. If there are more devices in the house in the house, it is possible to select collectors with an appropriate amount of outlet.

    Fittings for metal-plastic products

    The most important question that should clarify the home master is how to assemble metal-plastic pipes. Usually, special connecting elements are used for this purpose - fittings.

    They are two types:

    1. Press fittings (mounted presses).
    2. Screw (compression type).

    Mounting features with compression fittings

    These products are characterized by:

    • The strength of the compound is ensured by the pressure of the knurable nut on an incurred crimping ring;
    • The lack of need to look for special tools for connecting pipes: just two wrench keys, one of which hold the place of installation, and the other tighten the crimping nut;
    • the need to apply with the laying of metal-plastic pipes with their own hands as little intermediate connections;
    • the possibility of gradually loosening the strength of the connection, as a result of which it is necessary to stretch the crimping nuts from time to time; Because of this, stacked the pipes mounted in this way in the walls or floors is not recommended.

    You can avoid the last problem by replacing crimping products with press fittings.

    Mounting features using press fittings

    Such products are more reliable and durable (service life is at least 50 years), withstands working pressure up to 10 bar and provides ease of installation of the pipeline.

    The only drawback is the need to apply a special press machine, manual or hydraulic with a microprocessor.

    1. Sliced ​​a piece of pipe of the desired length.
    2. Remove the face with the ends and customize the diameter of the product.
    3. They put on the end created from stainless steel sleeve.
    4. Paste the prepared part of the pipe with the fitting until it stops.
    5. The gripping of the press car take a sleeve and compress it, pulling the press handle.

    Tips for mounting pipes from metalplastic

    For the connection to be durable, you should follow the following rules:

    • Pipes do not tolerate ultraviolet rays and mechanical damage, so it is possible to put them in the open way only where there are no these factors (read also: "How to build metal-plastic pipes - step-by-step management of the compounds");
    • With a hidden gasket, it is necessary to provide access to fittings, providing for the installation of various windows and removable panels during installation;
    • When you need to spend pipes through the house designs, select the sleeve with a diameter, large by 5-10 mm of a similar external parameter of the pipe. The gap creates a non-combustible material, which, when squeezed, contributes to the longitudinal promotion of the pipe;
    • When mounting products on the walls, use the suspension and supports supplied by the same manufacturer, and the metal parts of the fasteners areolate with a soft material;
    • It is impossible to allow damage to the product surface.

    In compliance with these tips, the assembly of the water supply system will be simple and not particularly expensive.

    Installation of metal-plastic pipes with their own hands

    When performing pipelines of any type of water supply today, the installation of metal-plastic pipes is successfully used.

    Metal plastic pipes due to their design have a number of advantageous advantage of them from other types of similar products.

    Assembling metal-plastic pipeline

    The advantages and device of pipes from metalplastic

    Constructively in metal-plastic pipes there are five layers:

    1. The inner layer of the product is made of cross-linked or compacted molecular polyethylene;
    2. The glue layer connecting the aluminum layer and polyethylene;
    3. Aluminum layer;
    4. The glue layer connecting the aluminum layer and the outer layer of plastic;
    5. Layer of plastic.

    Metal-plastic pipes have certain advantages relatively with similar products:

    • Metal-plastic pipes due to the polymer layer have high corrosion resistance.
    • Thanks to the layer of aluminum, the products are elastic and retain the form, whereby the installation of metal-plastic pipes of almost any complexity and configuration is possible.
    • Ideal accuracy in calculating linear dimensions is not required.

    Features Watering Watering System

    Montage with your own hands of metal-plastic pipes starts with a device of ball valves on a riser. For installation, it is necessary to choose exclusively high-quality ball valves that are capable of operating at high operating pressure (within 60 atmospheres) and a temperature of 150 degrees.

    Chinese fakes should be avoided, because in the water supply system, much depends on the quality of the cranes.

    It is the ball crane in a situation with the appearance of leaks, you can overlap the flow of water in the apartment.

    Scheme of a metal-plastic pipeline system

    Next, the installation of water pipes from metal plastic pipes is performed in such a sequence:

    1. Deep cleaning filter and water meter;
    2. Filter of fine cleaning;
    3. Pressure reducer;
    4. The collector from which the layout is made and the installation of pipes from metalplastic to directly plumbing devices.

    Metal plastic pipes are mounted together with filters to secure plumbing devices and the pipes themselves from small particles of sand, metals, Okalin present in risers in significant quantities.

    The collector installation is required to ensure uniform water supply to consuming elements - sink, toilet bowl, washing machine, from a water rummer. As a rule, collectors have 2, 3 or 4 outputs. In the event that the number of consuming devices more than four, select such collectors that have the required number of outputs.

    Pipes for pipes from metalplastic

    If metal-plastic pipes are required - installation and immediately compound is performed using fittings for metal-plastic pipes, which are the following types:

    Connection of pipes by compression fittings

    Scheme of compression fitting

    Completion with compression fittings:

    • In the case of applying a compression fitting, the compound is obtained by pressure occurring in the process of spinning the nut on the crimping open ring.
    • To perform a compression compound, special tools for mounting metal-plastic pipes are not required .

    The connection is performed using two wrench: at the time when one is tightened to the nut, the other key is resistance.

    • If, when performing a wiring, metal-plastic pipes are used - the installation should be made to the device that consumes from the collector with one "thread", avoiding unnecessary connections.
    • After a while there may be a need for a broach to maintain the tightness of the compression fittings.

    But if we put into the floor or close the pipes with a tile, having several fitting connections, then the performance of this operation or dismantling of metal-plastic pipes in the event of such a need to become very difficult.

    To avoid periodic feeding of fittings, you will not remain anything, how to mount metalplastic pipes with press fittings.

    Compound of pipes from metalplastic with press fittings

    Press fittings are durable and durable (the warranty on them is up to 50 years), can withstand pressure up to 10 bar, and produced by their help of metal-plastic pipes is performed quickly and easily.

    Metal-plastic pipes with compound press fittings are installed using a special press machine. This tool for mounting metal-plastic pipes is simple manual and microprocessor hydraulic.

    Instructions for installing metal-plastic pipes with compound press fittings:

    1. The pipe is cut off with special scissors at right angles.
    2. Using a scan and a special tool for calibration, the chamfer is removed, and the pipe diameter is adjusted for the subsequent installation.
    3. A sleeve made of stainless steel is put on the tube.
    4. Up to the stop in the fitting pipe, the shaped part is inserted.
    5. The pressure clamp - manual or hydraulic - the sleeve is captured.
    6. Before the stop, the handles of the press are reduced.

    Rules for laying of a metal-plastic pipeline

    The pipeline from metal plastic is paved in accordance with the following rules:

    • By installing metal-plastic pipe, it is necessary to observe emergency accuracy, since the pipes are very sensitive to the effects of ultraviolet radiation, mechanical and thermal damage.

    An open gasket of such pipes is permissible exclusively in such places where there is no impact of these factors.

    • Mounting technology of metal-plastic pipes with a hidden gasket provides for the device of hatches and removable shields to access compression type fittings. Such hatches and shields should not have sharp protrusions.
    • Installation of pipes through the designs of buildings is carried out using a sleeve with an inner diameter, by 5-10 mm exceeding the outer diameter of the pipe.

    The gap that is formed at the same time is filled with a soft non-aggravated material capable of ensuring the movement of the pipe in the longitudinal direction.

    • During the device of metal-plastic pipes for water supply or heating at each stage, it is necessary to remember the inadmissibility of the occurrence of scratches or cuts on the surface of the pipes.

    Example of a household water supply system scheme

    Unpacking the bay with a pipe, do not use sharp objects. When the pipe is marked, you must use exclusively a pencil or marker.

    • Metal-plastic pipe installation is made by means of supports or suspensions, with which the mounting to the wall is performed.

    Supports and suspensions are offered by pipe manufacturers. Metal fasteners need to be equipped with soft material gaskets.

    The pipeline from the metal plastic, made by its own hands, will last longer if the tips, instructions and recommendations will be fully respected.

    Installation of metal-plastic pipes with their own hands: Compound technology + wiring examples

    Modern materials for the arrangement of domestic highways made it possible to independently assemble water supply and heating systems. For example, the installation of metal-plastic pipes with their own hands allows you to arrange a tap or sewer wiring. To work with such elements, no complex tools or special skills are required.

    Features of metal-plastic products

    Metal-plastic (metal-polymer pipes) are composite products, for the production of which various types of materials apply. Such elements have an attractive appearance, good wear resistance, elasticity, strength.

    As a rule, the pipe consists of five layers. A durable polymer is used as a carrier base, usually stitched polyethylene. It gives the smoothness of the inner surface, protecting it from blockages, and also contributes to the strength of the product.

    An adhesive substance is applied to the core, on which the aluminum foil stabilizing pipe is strengthened (it also prevents oxygen intake). The connection is secured by welding online or brass.

    The fourth layer is also applied with glue, to which the outer coating is connected - white polyethylene, providing the product with protection and aesthetic appearance that gives it aesthetic appearance.

    Technical characteristics of pipes D 16-20 mm

    We present the data characteristic of metal-plastic pipes of common diameters (16 and 20 mm):

    • The wall thickness is respectively 2 and 2.25 millimeters; The thickness of the aluminum layer is 0.2 and 0.24 mm.
    • One run-down meter weighs 115 and 170 grams and accommodates the volume of liquid equal to 1,113 and 0.201 liters.
    • The coefficient of thermal conductivity is 0.43 W / m to, the expansion of the metalplastic - 0.26x10 4 per 1 degree Celsius, the coefficient of roughness - 0.07.
    • With the transverse break of the material, the strength coefficient is 2880 H.
    • The adhesion strength of the adhesive layer with a foil is 70 H / 10 square meters, the strength coefficient of the aluminum welded layer - 57 H / sq. mm.
    • Metal-plastic pipes can even work at +95 ° C, briefly withstanding the temperature + 110-130 o C.
    • In the temperature boundaries from 0 to +25 o, the system functions at a pressure of up to 25 bar, and at +95 ° C withstands the pressure of 10 bar.
    • The tightness and integrity of the metal-plastic pipe is broken under the load of 94 bars (at +20 ° C).

    With the right installation and observance of the operational rules, the product from metal-planes can serve as 50 years and more.

    Advantages and disadvantages of metal-polymer

    The advantages of such products can be attributed:

    • Eastern of installation: Compounds of various categories of metal-plastic pipes are carried out quickly and easily;
    • high heat resistance (can be transported water heated to 100 ° C);
    • reasonable price (metal-polymer pipes are cheaper than metal and most plastic analogs);
    • High strength, ring rigidity;
    • corrosion resistance, aggressive environments;
    • no clock to the formation of sediments and blockages;
    • aesthetic appearance;
    • high bandwidth;
    • low thermal conductivity;
    • sufficient plasticity;
    • the possibility of light repair;
    • durability.

    The main disadvantage of such products lies in the fact that the metal and plastic, of which they consist of pipes, have different expansion indicators. Regular temperature differences of the agent in the pipes can lead to a weakening of fasteners, which is why there are flows in the design.

    To avoid this, experts advise, making installation, always provide a certain supply when joint joints. It will also be useful because metal-plastic systems are poorly withstanding the hydrowards.

    Scope of application of metal-plastic elements

    Pipes made of metal-polymer are widely used in the arrangement of individual houses, in industrial construction and agriculture.

    The main areas of their use are:

    • transportation of liquids, gaseous agents;
    • laying of drainage systems, water pipes, heating;
    • in structures involving the transfer of compressed air;
    • Podding the components of heating to radiators, a warm-alone device;
    • Installation of air-conditioning schemes;
    • protection and shielding of wires (primarily power);
    • The structure of watering systems.

    Metalplastic is not recommended to apply:

    • When organizing central heating systems with an intended device of elevator nodes;
    • in places with a prescribed fire safety level "G";
    • With the intended supply of hot liquid in the pipeline with a working pressure> 10 bar;
    • In rooms where it is planned to place the sources of thermal radiation with a surface temperature of above 150 degrees C.

    In addition, metal-polymer pipes are undesirable to use in safety, signal, overflow, expansion schemes and in fireproof water pipes.

    Three main ways of pipe wiring

    Wiring of metal-plastic systems can be carried out by different methods, each of which is chosen on the basis of the feasibility and possibilities of further access to the system.

    Option # 1: Hidden

    In this case, all pipes and connections are hidden in the depth of the wall under finishing materials. Alternatively, only fittings and taps for connecting plumbing devices are displayed.

    When using this method of installation, the interior design is preserved, in addition, the masking of communications protects them from random damage.

    This option has several minuses:

    • To lay the channels for pipes, a complex and time-consuming process of sticking is required. After laying communications, the surface has to restore again.
    • Such a way is not suitable for bearing walls, where it is forbidden to carry out the launch of regulatory documents.
    • A fairly high cost associated with extension work.

    This way it is better to take advantage of the repair in the bathroom. It is impractical to arrange a hidden gasket in the already decorated room, since it will take a complete dismantling of the wall covering (facing, plaster).

    Option # 2: Open

    If the pipes for any reason can not be covered in the wall, they can be paved along its surface. This option is more convenient for visual control over connectivity places, which allows you to quickly clean the site or replace the component.

    An open layout can be used in rooms with already repaired, since the installation will not harm the design of the walls. The advantages of this method include its ease and lower cost of work than when laying internal communications.

    Option # 3: Combined

    In this case, the pipes are carried out on the surface of the indistened walls, after which they are closed by boxes or false panels. This is a rather complicated way, since it requires perfect fit into the interior of decorative elements, which can also use plasterboard, tiles and other materials.

    Schemes for bathroom and bathroom

    With plumbing works carried out in bathrooms and toilets, three layout of metal-plastic pipes can be used. For private houses, the use of the collector is the most rational.

    Effective collector system

    A reliable and practical option involving the connection of each object to the central tube through the entrance pair. This allows the crane to adjust or turn off the water supply to each specific plumbing.

    All regulatory devices are located in a compact manifold, which is placed in the space specifically allocated to them (cabinet).

    Drinking pipes that have a minimum of compounds do not require special control, which allows the gasket to be laid in a hidden way. The disadvantage of this option is quite high cost, because for each connection you will need to purchase a special shut-off crane. Since such a system is quite complicated, it is necessary to produce neatly and carefully.

    An important advantage: in case of failure of a separate item (washing machine, mixer), there is no need to completely disconnect the bathroom from the water supply - it is enough to turn off the desired shut-off valve.

    Sequential system of connections

    This option involves the connection of each SANTEXPEDMET to the main pipe with a separate tee. It is more suitable for bathrooms with a minimum number of objects (washing machine, a common mixer).

    The consistent scheme can be implemented already after completion in the room of finishing, using an open laying system. The assembly process is quite simple: the pipe is laid from one item to another, at the same time the underlining element is displayed from the tee.

    This option requires minimal financial costs. It should be noted that with a large number of points for the fence of the pressure fluid may not be enough, and the system will function with difficulty or even fail.

    Wiring system with passage sockets

    Connecting plumbing devices is similar to consistent, but instead of tees, outlets are used. This scheme is usually applied only in individual houses, since it requires a large-length pipe laying, as well as the installation of an additional pump, which will help ensure the necessary water pressure.

    When performing connecting works with metal-plastic pipes, several important nuances should be taken into account:

    • When developing a design, it is desirable to provide for at least connections.
    • It is important to apply the pipe and connecting couplings made from the same material.
    • For the pipeline it is better to use thermal insulation that allows preventing condensate sedimentation.
    • It is necessary to provide free access to the accounting devices, filters, detachable connections.

    Compliance with the rules will create a reliable system capable of listening for many years.

    Wiring of sewage pipes

    The work on the installation of sewage metal-plastic pipes has its own features.

    In this case, it is important to comply with the following requirements for the unobstructed drainage removal with blockage prevention.

    • To withstand a slope (0.02-0.03 from the holistic length of the design) towards the drain collector.
    • It is forbidden to put taps at an angle of 90 degrees when installing structures.
    • The need to install special tees with removable lids (revisions) in areas before turning inclined to form blocks.
    • When laying the system with a hidden way, it is important opposite the audit to leave viewing windows.
    • Collecting the system, it is important to leave a stock intended for the temperature expansion of the product.

    To install sewage, it is necessary to use pipes, the diameter of which ensures easy wastewater permeability. For the toilet bowls, it is recommended to use products with a diameter of at least 100 mm, for baths and sinks - enough 50-75 mm.

    Rules for installation of metal-polymer structures

    When laying metal-plastic systems, it is important to be guided by the following provisions:

    • With a hidden laying of pipelines from this material, it is important to provide removable shields (hatches) devoid of sharp protrusions. They provide access to compression fittings.
    • Stacking systems through structures of buildings It is important to produce with the help of a sleeve, the inner diameter of which is 0.5-1 cm more similar to the pipe parameter. The gap that is formed between the elements must be filled with a soft non-combustible material that ensures the movement of the pipe in the longitudinal direction.
    • When laying metal plastic water supply or heating systems, it is important to prevent damage to the surface of the elements, including scratches or cuts. To unpack the bay, it is better to avoid sharp objects, and the design markup is performed with a pencil or a marker.
    • Installation of construction can be carried out using support or suspension, which are usually present in the range of metal-polymer pipe manufacturers. They help attach products to the wall, while the metal parts are installed with gaskets made of soft material.

    All stages of operations need to be carried out carefully and neatly, since metal-plastic elements are sensitive to ultraviolet, mechanical damage. The outer installation of such structures is appropriate only in places where there are no similar factors.

    Tools and materials for pipe gasket

    For laying metal-polymer systems, minimum devices and materials are required, but it is better to choose high-quality devices and pipes.

    Fixtures for mounting pipelines

    To create a construction of metal-plastic, a fairly modest set of tools: pipe cut, the simplest pipe bending, sliding and precipitated keys.

    Truborez is needed to separate dimensional cuts of the pipe from the bay. Since metalplastic is sufficiently supportive material, it can be cut with a metal knife or even a sharp knife. However, the perfect perpendicularity of lines, without which it is difficult to obtain a hermetic compound, can be obtained only when using a special cutter.

    The keys of different species are important for installation and assembly of threaded connections on pipeline fittings. With an extreme need, you can do with one precipitant key, however, it is better to use two precipitated and one-aligned key for comfortable work.

    Caliber is an important tool for creating an accurate and sealed connection of the pipe with a fitting: it allows you to center the plane of the slice and remove the champecker from the inside of the product.

    The pipe bender allows you to change the configuration of the element, which can be saved on the corner fittings. It is especially important to have this tool if the design involves a large number of angular conjugations.

    What materials are required

    For laying the pipeline, it is important to stock in the following components:

    • pipes (bay, measuring segments);
    • various options for fittings (bypass, tees, corners), with which certain areas of pipes turn into a single system;
    • Fasteners - folding clamps and clips, with which metal-plastic structures are fixed on support surfaces, most often on the wall.

    It is important to choose all the necessary materials and tools in advance, to then freely exercise all the work.

    Marking of pipeline lines

    Before starting work, it is important to consider how pipes will be placed. When developing a scheme, it is desirable:

    • Apply the lines of the pipeline directly on the walls of the room, where it is planned to lay, which contributes to the visualization of the structure.
    • As the starting point, use the plug connection area to the crane or the radiator, which must already be installed before the installation.
    • Minimize the number of tees and crosses affecting the stability of the pressure, as well as minimize the number of other fittings.
    • For the corner laying of metal-plastic pipes, you can use pipe bend or corner fittings.
    • All connecting element should provide free access, as the fasteners on the thread need periodic pulling into order to avoid leaks.

    Installation of connecting elements must be performed after the calculations and markup of the structure.

    Fittings Review for Metal Flast System

    To prepare for work, it is important to cut the pipes to the sections required for the length, while all the cuts should be carried out strictly at right angles. If in the process cutting the pipe is deformed, it must be aligned with a caliber (it will help to remove the internal chamfer).

    For the installation of the design, various types of fasteners apply, we will stop separately.

    Option # 1: collet

    Collet fittings, consisting of a housing, crimp ring, rubber gasket, have a detachable design, so you can apply several times. The carving of parts allows you to combine them with household appliances.

    To connect the connecting elements to the pipe, you need to wear a sequential nut and ring. Insert the resulting structure into the fitting, tighten the nut. To make the pipe easier to the connecting element, it is desirable to moisten.

    Option # 2: Compression

    Widely used parts used for connecting pipes that can be called concentrated. Before installation, it is important to make sure that the sealing rings and the dielectric pads, which must be on the part shank.

    To connect to the end of the pipe, a nut and a crimp ring is put on (if it has a cone form, then the process is carried out with a narrower side of the part). After that, the shank is inserted into the pipe (for this you need to make some effort), while in order to seal items, the part is covered with packles, flax, sealant.

    The next step on the fitting body is put on and tightened by a cape nut. It is convenient to do this with the help of two keys: one of them is fixed the item, another nuts.

    This method is sufficiently easy and does not require the use of special equipment, but it is undesirable to apply for hidden wiring, since it requires a connection check.

    Option # 3: Push fittings

    Comfortable connecting elements, for fastening which special tools are not needed. To install, it is enough to insert the product into the connecting part, while the end of the pipe should be visible in the viewing window.

    Immediately at the end of the installation, thanks to the enabled water jet, the fitting wedge pushes forward, forming a clamp that prevents leakage.

    This method allows you to quickly and easily create the necessary design, providing high-quality durable connections. Almost the only lack of push fittings is their high cost.

    Option # 4: Press fittings

    These items are used to create in-view connections using press ticks or similar devices.

    To connect, you need to calibrate the item, removing the fez with it, after which the sleeve is put on it and the fitting is inserted. The sleeve is captured by the press clamp, after which the handle information is tightly clamped.

    Such an element can be used only once, however mounted with fastenings are quite sealed and reliable, so that they are suitable for hidden wiring.

    Installation of pipes from different types of materials

    For the connection of the elements, one of which is made of metal, and the second - from the metal plastic, the special fittings are intended, one end of which is equipped with a thread, and the second is a socket.

    For installation, the metal pipe must be chopped by carvings, clean the palauls, lubricate with soap or silicone, and then throw the fitting with your hand. After the second end is connected to the plastic element, the thread is tightened completely using the key.

    Assortment of Fittings of Different Forms

    For easy installation, the connecting elements may have a different form. Most often found:

    • adapters for connecting pipes with different diameters;
    • Tees, providing branches from the central pipe;
    • corners to change the flow direction;
    • Equipment (installation knee);
    • Crosses, allowing to organize different flow directions for 4 pipes.

    A special configuration (couplings, triangles, tees) may have press fittings.

    Installation of metalplastic pipes

    Metal-plastic (metal-polymer) pipes are composite pipes made from a polymer pipe reinforced with metal.

    They are durable, durable, easy to install, resistant to aggressive media and are very often used in constructing water pipelines, warm floors, compressed air transport systems and various liquids (including chemically aggressive), for laying electrical wires and cables.

    What is it

    Combined metal-plastic pipes consist of five layers:

    • external protective layer of stitched polyethylene;
    • inner layer of edible plastic;
    • Between the layers of polyethylene lies the reinforcing aluminum shell;
    • Aluminum and layers of polyethylene are bonded with adhesive layers.

    Photo: Metal Pipe Structure

    This design ensures the unique properties of metal-plastic pipes:

    • Pipes from metalplastic easily bent, they cut and hold the attached shape, due to the aluminum core;
    • The outer and outer layer of polyethylene have high anti-corrosion resistance and protect the inner sheath of aluminum from the effects of moisture and aggressive media;

    These features of the design determine the ease and ease of installation of metal-plastic pipes, their reliability, durability and extensive conditions of application.

    Specifications

    The main technical characteristics include:

    • Diameter of pipe . Metal-plastic pipes are produced with a diameter of 16 to 53 mm. Pipes with a diameter of more than 40 mm are practically not used in housing, pipes with a diameter of 40 and 32 mm are actively used when the water supply network is wiring in a private house. The most popular and cheap pipes are 16 mm, fittings for them are significantly cheaper than others. However, their and 20 mm pipes should be applied only in central water supply networks at normal pressure in the plumbing network;

    Photo: pipe diameters and table diameter table for heating

    • Thickness of walls pipe (maybe 2 or 3.5 mm);
    • Permissible bend radius . It lies within 80-550 mm with manual bending and 50-180 when applying pipe-bending.

    Connection methods

    For the connection, special connectors (fittings) are used.

    Fittings for pipe data are two types:

    • compression threaded fittings;
    • Press fittings.

    Advantages of using fittings

    • Fast and easy installation;
    • No welding is required;
    • the complexity of the process of installation of water supply systems and heating systems is reduced;
    • Special skills are not required to perform work;
    • A very easy way to perform a combination of metal-plastic pipes with pipes of other species (steel, copper, plastic).

    Compression threaded fittings

    Compression fittings with carvings for metal-plastic pipes are the most expensive. They make it possible to perform collapsible compounds.

    A large range of collapsible compression fittings of various types is produced.

    Varieties of threaded compression fittings:

    • Corners: Nut-Tsang, Tsang-Tsang, Tsang-Fitzer;

    Press fittings

    Press fittings When installing are widely used when working on a device of hot and cold water systems, when installing heating systems, warm floors.

    Photo: Fitting Press Scheme

    This is due to the fact that the press fittings have the following advantages over compression:

    • A hidden laying of pipelines is allowed;
    • Pulley is allowed;
    • Connections are extinct. There is no need for an annual prophylactic tightening of nuts in places of pipe compounds;
    • The maximum allowable working pressure in the joints of the joints up to 10 atm:
    • Connection service life using a fitting press is up to 50 years.

    Restricts their application only the need to use in the installation of special presses (manual or automatic), which are not suiced.

    A wide range of fittings is available under the press, allowing you to collect the pipeline of any necessary configuration:

    • Nut tightened from the hands to the fitting. It should spin easily. If the nut goes tight, then it is not on the thread. You need to try to unscrew and re-spin the nut;
    • Two adjustable or horn keys are taken. One is held the housing of the nut, another nut is checked for 2-3 turns;
    • Check the collected system to flow.

    Photo: Calibration

    • A special crimp coupling is put on the pipe;
    • A special isolating gasket for protection against electrocorrosion is put on the fitting fitting;

    Photo: Installing a press fitting

    • The fitting of the fitting is carefully inserted into the pipe and crimped with press clamp;

    Photo: Pressing

    • With proper burning, two uniform rings should appear on the fitting coupling;
    • Some manufacturers have a connecting coupling of the fitting press initially fixed on the fitting, so after preparing the pipe at the connection site, the pipe is immediately sisted on the fitting.

    The correct planting of the pipe on the fitting is controlled through the hole in the coupling and the coupling is crimped.

    Important! It is allowed only to crimp the connection with the press clamp. Repeated crimping is categorically prohibited!

    Montaja rules

    When performing installation work, it is important to comply with the following rules:

    • Store pipes before installation is recommended in a closed room, no closer to 1 meter to heating devices. Permissible storage under a canopy;
    • carry out installation work at a temperature not lower than + 10ºС;
    • do not unload rolls with pipes dropping from height;
    • If metal-plastic pipes were transported at low temperatures, it is necessary to withstand them in the room during the day;
    • The open gasket of metal-plastic pipes is admissible in places protected from mechanical and thermal effects, and the effects of ultraviolet;
    • Before starting work on the laying of pipes, all fire and welding works should be completed;
    • With the opening of metal-plastic pipes, their gasket is allowed only at the end of all finishing works in the room;
    • When conducting markup, it is unacceptable to use sharp items;
    • It is unacceptable to twist the pipes when installing or allowing excessive inflection;
    • The bending of pipes can be manually;

    In this case, the bending radius should not exceed 5 diameters of the pipe. If you need a greater bend, you need to use a special tool for flexing metal-plastic pipes.

    • Pipes from metalplastic are very flexible, so they must be fixed. With open gasket with metal-plastic pipes, special fixing clips use. In the horizontal layout of the pipes are fixed every 0.5 meters, and with vertical - after 1 meter;
    • All pipeline fittings must be fixed in such a way that avoiding the transmission of the load on the pipes;
    • If necessary, spend a pipe through a wall or other design, you need to use special sleeves.

    Application

    The scope of application is very extensive:

    • Hot and cold water supply systems;
    • a device of outdoor and wall-mounted recession heating ("warm floors" and "warm walls");
    • radiator heating systems, at a circulating coolant temperature not higher than 95 degrees;
    • watering systems;
    • open areas heating systems;
    • soil heating systems in greenhouses, greenhouses, greenhouses;
    • The blockage of heat curtains and water calorifications at a circulating coolant temperature is not higher than 95 degrees;
    • device of fuel lines and industrial pipelines for transportation of non-food and food liquids;

    Installation of water pipes

    Metal plastic pipes are a great option for the device of a hot and cold water supply system in a private house or in the apartment.

    When choosing pipes for the installation of water supply systems, it is necessary to take into account the operating pressure of the system and the temperature (when installing hot water systems).

    Hot water systems are recommended to be installed using the press fittings.

    The installation of water pipes from metal plastic pipes is carried out in the following order:

    • The concept of water pipeline is being developed, on the basis of which the assembly circuit is drawn with pipe wiring indoors. It is recommended to design a plumbing with a minimum number of connectors;

    Photo: Installation of water pipes from metalplastic pipes

    • According to the mounting scheme, the required length of the water pipes, the desired number of fittings of various types;
    • The installation of pipes are scheduled on the mounting scheme. The required number of fasteners is calculated. For fasteners, special clips are used (plastic locks);
    • Defined with the type of fittings. If you plan to collect water pipes with your own hands and it is not possible to buy or rent a press clamp for mounting the press of fittings, then we choose a compression fitting, for the installation of which it is enough to have a pair of spanning keys of the desired size at hand;

    Fittings are the weak link in the plumbing system, so do not save on fittings and buy the cheapest models.

    • The installation of the pipeline according to the scheme is made (the fixing clips are installed in the outlined places, the pipes are bred, fittings are mounted);
    • In the installation process, metal plastic pipes are flexible. Flexible pipes from metalplastic is performed manually or using a special spring, which is inserted into the pipe;

    Photo: Bending of metalplastic pipes

    Important! In the process of bending, it is necessary to observe the maximum allowable bending radii of metal-plastic pipes, the excess of which is fraught with a violation of the integrity of the pipe.

    • After the installation is completed, the testing of the system on tightness, the identified leaks are eliminated.

    Installation of pipes for heating

    Metal-plastic pipes are increasingly used when installing various heating systems.

    Installation of hidden heating systems lead using exclusively press fittings.

    When installing open heating systems, it is permissible to use threaded connectors.

    Photo: Installation of metalplastic pipes for heating

    When installing the heating systems, it is necessary to take into account the following recommendations:

    • The fastening of heating pipes should be carried out in a step of no more than 0.5 m. With a larger step, it is possible to sagging pipes between fasteners, which is fraught with a violation of the circulation of the coolant in the system;
    • Pipes should be calculated on the temperature of 95º C and the operating pressure from 6.6 atmospheres;
    • When choosing pipes, it is necessary to pay attention to the availability of quality certificates.

    Installation of a warm floor

    Metal plastic pipes today are the most affordable and economical optional installation of warm floor systems. They are easily bent, perfectly hold the form, easy to install and operate and serve for a long time.

    Photo: Warm floor scheme

    Installation of a warm flooring system is carried out using the press of fittings, therefore, to fulfill the crimping system, it is necessary to find the press of pliers, or invite specialists.

    When installing the system of warm floors, the pipe is placed by snake, meander or spiral. The total length of one loop should not exceed 100 meters.

    Photo: Laying pipes of a warm floor with a spiral and snake Photo: Snake Spiral

    With a high length there will be ineffective heat transfer. When laying loops, provide a distance between them.

    Pipe consumption rate with warm floors: 7 robes per square meter room.

New products made it possible to assemble the water supply system and heating itself, not attracting plumbers. Pipelines serve for a long time, simply simply and quickly mounted, without creating problems even inexperienced masters.

    After performing the installation of metal-plastic pipes with their own hands, you can safely save, while retaining the family budget for more important costs. To install their home master you need only easy to use tool, patience and knowledge that we are ready to share with site visitors.

    We will tell you all about the specifics of the use of metal-plastic products and methods of connection assembled from them pipelines. The article describes in detail the negative and positive aspects of their use. With us you will learn how to install trouble-free systems.

    Features of metal-plastic products

    Metal-plastic (metal-polymer pipes) are composite products, for the production of which various types of materials apply. Such elements have an attractive appearance, good wear resistance, elasticity, strength.

    Metal plastic pipes

    Metal-plastic pipes are characterized by high consumer qualities (strength, flexibility, resistant to high temperatures and aggressive substances), as well as aesthetic appearance

    As a rule, the pipe consists of five layers. A durable polymer is used as a carrier base, usually stitched polyethylene. It gives the smoothness of the inner surface, protecting it from blockages, and also contributes to the strength of the product.

    An adhesive substance is applied to the core, on which the aluminum foil stabilizing pipe is strengthened (it also prevents oxygen intake). The connection is secured by welding online or brass.

    Device of metalplastic pipe

    The design of the metal-plastic pipe involves the use of five layers of various materials: two layers of polyethylene, two layers of glue, aluminum foil layer

    The fourth layer is also applied with glue, to which the outer coating is connected - white polyethylene, providing the product with protection and aesthetic appearance that gives it aesthetic appearance.

    Technical characteristics of pipes D 16-20 mm

    We present the data characteristic of metal-plastic pipes of common diameters (16 and 20 mm):

    • The wall thickness is respectively 2 and 2.25 millimeters; The thickness of the aluminum layer is 0.2 and 0.24 mm.
    • One run-down meter weighs 115 and 170 grams and accommodates the volume of liquid equal to 1,113 and 0.201 liters.
    • The coefficient of thermal conductivity is 0.43 W / m to, the expansion of the metalplastic - 0.26x10 4per 1 degree Celsius, roughness coefficient - 0.07.
    • With the transverse break of the material, the strength coefficient is 2880 H.
    • The adhesion strength of the adhesive layer with a foil is 70 H / 10 square meters, the strength coefficient of the aluminum welded layer - 57 H / sq. mm.
    • Metal plastic pipes can even work at +95 оC, briefly withstanding temperatures + 110-130 оFROM.
    • In the temperature borders from 0 to +25 оWith the system functions at a pressure of up to 25 bar, and at +95 оWith withstands the pressure of 10 bar.
    • The tightness and integrity of the metal-plastic pipe is broken at a load of 94 bars (at +20 оFROM).

    With the right installation and observance of the operational rules, the product from metal-planes can serve as 50 years and more.

    Advantages and disadvantages of metal-polymer

    The advantages of such products can be attributed:

    • Eastern of installation: Compounds of various categories of metal-plastic pipes are carried out quickly and easily;
    • high heat resistance (can be transported water heated to 100 ° C);
    • reasonable price (metal-polymer pipes are cheaper than metal and most plastic analogs);
    • High strength, ring rigidity;
    • corrosion resistance, aggressive environments;
    • no clock to the formation of sediments and blockages;
    • aesthetic appearance;
    • high bandwidth;
    • low thermal conductivity;
    • sufficient plasticity;
    • the possibility of light repair;
    • durability.

    The main disadvantage of such products lies in the fact that the metal and plastic, of which they consist of pipes, have different expansion indicators. Regular temperature differences of the agent in the pipes can lead to a weakening of fasteners, which is why there are flows in the design.

    To avoid this, experts advise, making installation, always provide a certain supply when joint joints. It will also be useful because metal-plastic systems are poorly withstanding the hydrowards.

    Metal-plastic pipes are used in the organization of cold and hot water supply, in the device of systems of conventional and floor heating, water treatment pipelines for pools, greenhouses, greenhouses, etc.

    Due to the presence of an aluminum layer between the outer and inner polymer sheath, the pipes metalplastic lines operate in systems with a pressure of up to 10 bar

    A valuable advantage of metal-plastic pipes is the flexibility to reduce the length of the track and use the minimum of connecting fittings

    Pipes from metalplastic apply in the construction of new pipelines and in repair work, they work excellently in tandem with all existing pipe types

    The timing of metal-plastic pipes, exceeding 50 years, their reliability and minimal expansion, compensated by the metal component, allows you to lay pipelines with a hidden way. Although in rare cases in small areas they are laid open

    The flexibility of metal-plastic products is ideal for the device for collector wiring and outdoor heating systems

    To form durable compounds of metal-plastic pipes, build branched systems, fittings are produced by fittings

    Compounds of metal-plastic pipes are manufactured using press fittings installed by crimping and compression fittings mounted using a clamping nut

    Scope of application of metal-plastic elements

    Pipes made of metal-polymer are widely used in the arrangement of individual houses, in industrial construction and agriculture.

    The main areas of their use are:

    • transportation of liquids, gaseous agents;
    • laying of drainage systems, water pipes, heating;
    • in structures involving the transfer of compressed air;
    • Podding the components of heating to radiators, a warm-alone device;
    • Installation of air-conditioning schemes;
    • protection and shielding of wires (primarily power);
    • The structure of watering systems.

    Metalplastic is not recommended to apply:

    • When organizing central heating systems with an intended device of elevator nodes;
    • in places with a prescribed fire safety level "G";
    • With the intended supply of hot liquid in the pipeline with a working pressure> 10 bar;
    • In rooms where it is planned to place the sources of thermal radiation with a surface temperature of above 150 degrees C.

    In addition, metal-polymer pipes are undesirable to use in safety, signal, overflow, expansion schemes and in fireproof water pipes.

    Metal plastic pipes for heating

    Metalplastic products are widely used in private and industrial construction. In this photo, pipes used for laying heating systems are presented.

    Three main ways of pipe wiring

    Wiring of metal-plastic systems can be carried out by different methods, each of which is chosen on the basis of the feasibility and possibilities of further access to the system.

    Option # 1: Hidden

    In this case, all pipes and connections are hidden in the depth of the wall under finishing materials. Alternatively, only fittings and taps for connecting plumbing devices are displayed.

    Hidden method of pipe wiring

    The hidden way of installation involves the installation of the structure in the wall, where the filings are specially prepared for pipes, after which the surface is closed

    When using this method of installation, the interior design is preserved, in addition, the masking of communications protects them from random damage.

    This option has several minuses:

    • To lay the channels for pipes, a complex and time-consuming process of sticking is required. After laying communications, the surface has to restore again.
    • Such a way is not suitable for bearing walls, where it is forbidden to carry out the launch of regulatory documents.
    • A fairly high cost associated with extension work.

    This way it is better to take advantage of the repair in the bathroom. It is impractical to arrange a hidden gasket in the already decorated room, since it will take a complete dismantling of the wall covering (facing, plaster).

    Option # 2: Open

    If the pipes for any reason can not be covered in the wall, they can be paved along its surface. This option is more convenient for visual control over connectivity places, which allows you to quickly clean the site or replace the component.

    External layout of pipes

    When the method is open, the laying of pipes is made over the wall surface, which allows control of compounds and reduces the cost of work.

    An open layout can be used in rooms with already repaired, since the installation will not harm the design of the walls. The advantages of this method include its ease and lower cost of work than when laying internal communications.

    Option # 3: Combined

    In this case, the pipes are carried out on the surface of the indistened walls, after which they are closed by boxes or false panels. This is a rather complicated way, since it requires perfect fit into the interior of decorative elements, which can also use plasterboard, tiles and other materials.

    Schemes for bathroom and bathroom

    With plumbing works carried out in bathrooms and toilets, three layout of metal-plastic pipes can be used. For private houses, the use of the collector is the most rational.

    Effective collector system

    A reliable and practical option involving the connection of each object to the central tube through the entrance pair. This allows the crane to adjust or turn off the water supply to each specific plumbing.

    Collector with shut-off cranes

    With parallel wiring, each plumbing device is equipped with its own tap line and its shut-off valve. All branches come out of one device - collector

    All regulatory devices are located in a compact manifold, which is placed in the space specifically allocated to them (cabinet).

    Drinking pipes that have a minimum of compounds do not require special control, which allows the gasket to be laid in a hidden way. The disadvantage of this option is quite high cost, because for each connection you will need to purchase a special shut-off crane. Since such a system is quite complicated, it is necessary to produce neatly and carefully.

    Collective pipe layout diagram

    In the collector tap wiring, control devices and locking devices are installed on the pipe supplying water to the collector

    An important advantage: in case of failure of a separate item (washing machine, mixer), there is no need to completely disconnect the bathroom from the water supply - it is enough to turn off the desired shut-off valve.

    Sequential system of connections

    This option involves the connection of each SANTEXPEDMET to the main pipe with a separate tee. It is more suitable for bathrooms with a minimum number of objects (washing machine, a common mixer).

    Sequential layout of pipes

    Sequential wiring, schematically shown in the figure, is recommended to be used for premises with a small number of objects that are alternately connected to pipes with tees

    The consistent scheme can be implemented already after completion in the room of finishing, using an open laying system. The assembly process is quite simple: the pipe is laid from one item to another, at the same time the underlining element is displayed from the tee.

    This option requires minimal financial costs. It should be noted that with a large number of points for the fence of the pressure fluid may not be enough, and the system will function with difficulty or even fail.

    Wiring system with passage sockets

    Connecting plumbing devices is similar to consistent, but instead of tees, outlets are used. This scheme is usually applied only in individual houses, since it requires a large-length pipe laying, as well as the installation of an additional pump, which will help ensure the necessary water pressure.

    When performing connecting works with metal-plastic pipes, several important nuances should be taken into account:

    • When developing a design, it is desirable to provide for at least connections.
    • It is important to apply the pipe and connecting couplings made from the same material.
    • For the pipeline it is better to use thermal insulation that allows preventing condensate sedimentation.
    • It is necessary to provide free access to the accounting devices, filters, detachable connections.

    Compliance with the rules will create a reliable system capable of listening for many years.

    Wiring of sewage pipes

    The work on the installation of sewage metal-plastic pipes has its own features.

    Sewage layout

    Sewer wiring made of metalplastic has a number of features. In this case, it is important to use pipes of a larger diameter, as well as take measures to organize a pipeline inclination

    In this case, it is important to comply with the following requirements for the unobstructed drainage removal with blockage prevention.

    • To withstand a slope (0.02-0.03 from the holistic length of the design) towards the drain collector.
    • It is forbidden to put taps at an angle of 90 degrees when installing structures.
    • The need to install special tees with removable lids (revisions) in areas before turning inclined to form blocks.
    • When laying the system with a hidden way, it is important opposite the audit to leave viewing windows.
    • Collecting the system, it is important to leave a stock intended for the temperature expansion of the product.

    To install sewage, it is necessary to use pipes, the diameter of which ensures easy wastewater permeability.

    For the toilet bowls, it is recommended to use products with a diameter of at least 100 mm, for baths and sinks - enough 50-75 mm.

    Rules for installation of metal-polymer structures

    When laying metal-plastic systems, it is important to be guided by the following provisions:

    • With a hidden laying of pipelines from this material, it is important to provide removable shields (hatches) devoid of sharp protrusions. They provide access to compression fittings.
    • Stacking systems through structures of buildings It is important to produce with the help of a sleeve, the inner diameter of which is 0.5-1 cm more similar to the pipe parameter. The gap that is formed between the elements must be filled with a soft non-combustible material that ensures the movement of the pipe in the longitudinal direction.
    • When laying metal plastic water supply or heating systems, it is important to prevent damage to the surface of the elements, including scratches or cuts. To unpack the bay, it is better to avoid sharp objects, and the design markup is performed with a pencil or a marker.
    • Installation of construction can be carried out using support or suspension, which are usually present in the range of metal-polymer pipe manufacturers. They help attach products to the wall, while the metal parts are installed with gaskets made of soft material.

    All stages of operations need to be carried out carefully and neatly, since metal-plastic elements are sensitive to ultraviolet, mechanical damage. The outer installation of such structures is appropriate only in places where there are no similar factors.

    Tools and materials for pipe gasket

    For laying metal-polymer systems, minimum devices and materials are required, but it is better to choose high-quality devices and pipes.

    Fixtures for mounting pipelines

    To create a construction of metal plastic, a fairly modest set of tools: pipe cut, the simplest pipe bending,, sliding and precipitated keys.

    Tools for mounting

    To install a metal-plastic system with your own hands, you need a minimum of tools that can be purchased in a set or separately with a construction supermarket.

    To separate the dimensional segments of the pipe from the bay, it is desirable to stock, intended for cutting metal-plastic pipes. Since metalplastic is sufficiently supportive material, it can be cut with a metal knife or even a sharp knife.

    However, the perfect perpendicularity of lines, without which it is difficult to obtain a hermetic compound, can be obtained only when using a special cutter.

    The keys of different species are important for installation and assembly of threaded connections on pipeline fittings. With an extreme need, you can do with one precipitant key, however, it is better to use two precipitated and one-aligned key for comfortable work.

    Caliber is an important tool for creating an accurate and sealed connection of the pipe with a fitting: it allows you to center the plane of the slice and remove the champecker from the inside of the product.

    The pipe bender allows you to change the configuration of the element, which can be saved on the corner fittings. It is especially important to have this tool if the design involves a large number of angular conjugations.

    Before starting work, we advise you to familiarize yourself with the rules and specifics.

    What materials will be required?

    For laying the pipeline, it is important to stock in the following components:

    • pipes (bay, measuring segments);
    • various options for fittings (bypass, tees, corners), with which certain areas of pipes turn into a single system;
    • Fasteners - folding clamps and clips, with which metal-plastic structures are fixed on support surfaces, most often on the wall.

    It is important to choose all the necessary materials and tools in advance, to then freely exercise all the work.

    With a sortiment of metal-plastic products for the assembly of pipelines will familiarize yourself.

    Marking of pipeline lines

    Before starting work, it is important to consider how pipes will be placed.

    When developing a scheme, it is desirable:

    • Apply the lines of the pipeline directly on the walls of the room, where it is planned to lay, which contributes to the visualization of the structure.
    • As the starting point, use the plug connection area to the crane or the radiator, which must already be installed before the installation.
    • Minimize the number of tees and crosses affecting the stability of the pressure, as well as minimize the number of other fittings.
    • For the corner laying of metal-plastic pipes, you can use pipe bend or corner fittings.
    • All connecting element should provide free access, as the fasteners on the thread need periodic pulling into order to avoid leaks.

    Installation of connecting elements must be performed after the calculations and markup of the structure.

    Fittings Review for Metal Flast System

    To prepare for work, it is important to cut the pipes to the sections required for the length, while all the cuts should be carried out strictly at right angles. If in the process cutting the pipe is deformed, it must be aligned with a caliber (it will help to remove the internal chamfer).

    Metal plastic pipes and fittings

    To connect metal-plastic pipes of different categories to a single design, connective elements are used - fittings that differ in design, size and fastening methods

    For the installation of the design, various, let's stop separately.

    Option # 1: collet

    Collet fittings, consisting of a housing, crimp ring, rubber gasket, have a detachable design, so you can apply several times. The carving of parts allows you to combine them with household appliances.

    To connect the connecting elements to the pipe, you need to wear a sequential nut and ring. Insert the resulting structure into the fitting, tighten the nut. To make the pipe easier to the connecting element, it is desirable to moisten.

    Option # 2: Compression

    Widely used parts used for connecting pipes that can be called concentrated. Before installation, it is important to make sure that the sealing rings and the dielectric pads, which must be on the part shank.

    Compression fitting for metal-plastic pipes

    Compression fittings are widely used in the device of metal-plastic structures. They make it easy to create connections without the use of special tools.

    To connect to the end of the pipe, a nut and a crimp ring is put on (if it has a cone form, then the process is carried out with a narrower side of the part). After that, the shank is inserted into the pipe (for this you need to make some effort), while in order to seal items, the part is covered with packles, flax, sealant.

    The next step on the fitting body is put on and tightened by a cape nut. It is convenient to do this with the help of two keys: one of them is fixed the item, another nuts.

    This method is sufficiently easy and does not require the use of special equipment, but it is undesirable to apply for hidden wiring, since it requires a connection check.

    Compression fittings intended for connecting metal-plastic pipes are installed using a simple wrench. Of particular preparation for this is not required, it is enough to disassemble the connector to the components: a precipitated nut, a split ring and a fitting

    Before installing compression fittings, we collect pipeline. In fact, place a place to install the connector.

    According to the markup, cut off the pipe. To make perfectly perpendicular cut, previous 10 cm align, only then cut at right angles

    Before performing a connection to a cold water pipe, wear corrugated insulation, if there is less than 10 cm between hot and cold branch (optional item)

    Calibrate pipe scan. First of all, we remove the landing chamfer on 1 mm calibration side. Then we curl the pipe with the other side about risks

    We wear a capped nut and a split ring on the pipe connected. The fitting is moisturous, dropping a while in a container with water, after which it is planted on the fitting the pipe so that it nevertheless rests on the edge of the fitting

    First, you manually screw the cape nut. It should be spinning without effort, if it was originally not on the thread, it is better to unscrew and put again. We reach the nut, using two keys: one hold the body of the fitting, the second turn the nut for 1-1.5 turns

    After assembly, run the system to check the quality of the connections. If necessary, tighten the cape nuts if looked at looseness

    Step 6: Installation of the Caid Nut and Sealer

    Step 7: Spinning of the Cape Nut

    Step 8: Connection quality control after assembly

    Option # 3: Push fittings

    Comfortable connecting elements, for fastening which special tools are not needed. To install, it is enough to insert the product into the connecting part, while the end of the pipe should be visible in the viewing window.

    Immediately at the end of the installation, thanks to the enabled water jet, the fitting wedge pushes forward, forming a clamp that prevents leakage.

    This method allows you to quickly and easily create the necessary design, providing high-quality durable connections. Almost the only lack of push fittings is their high cost.

    Option # 4: Press fittings

    These items are used to create in-view connections using press ticks or similar devices.

    Press fitting device

    Press fittings create hermetic durable connections, but they can only be used once. In addition, press clamps will be required to work with similar elements.

    For you need to calibrate the item, removing the fez with it, after which the sleeve is put on it and the fitting is inserted. The sleeve is captured by the press clamp, after which the handle information is tightly clamped.

    Such an element can be used only once, however mounted with fastenings are quite sealed and reliable, so that they are suitable for hidden wiring.

    Installing press fittings is performed in the following order:

    For the connection of the elements, one of which is made of metal, and the second - from the metal plastic, the special fittings are intended, one end of which is equipped with a thread, and the second is a socket.

    For installation, the metal pipe must be chopped by carvings, clean the palauls, lubricate with soap or silicone, and then throw the fitting with your hand. After the second end is connected to the plastic element, the thread is tightened completely using the key.

    Assortment of Fittings of Different Forms

    For easy installation, the connecting elements may have a different form. Most often found:

    • adapters for connecting pipes with different diameters;
    • Tees, providing branches from the central pipe;
    • corners to change the flow direction;
    • Equipment (installation knee);
    • Crosses, allowing to organize different flow directions for 4 pipes.

    A special configuration (couplings, triangles, tees) may have press fittings.

    Conclusions and useful video on the topic

    In the video below, plumbing will tell, how to quickly and quickly mount the structures of metal-plastic pipes:

    The use of the right methods and high-quality components allows you to create strong metal-plastic systems that will serve for a long time without leaks, repair and unnecessary material spending.

    To tell about how you installed and plugged metal-plastic pipes, it is possible in the block below. Comment, please, submitted by us. Specify questions, share useful information and thematic photographs.

    The introduction of pipes of different diameters and destination made it possible to expand the installation capabilities of the water supply, sewage and heating. Metal-plastic pipes are in high demand, and the reason for this is the operational capabilities, the price and specifications. But so that the wire of communication systems is reliable, it is worth paying attention to the installation option.

    Ensuring uninterruptible communication supply

    Installation of metalplastic pipesToday, without sewage, heating or water can not do any branch of human life. To ensure uninterrupted supply, products of different diameters and purpose of polypropylene, metal or metalplastic are used.

    The last option is preferable to several aspects: low price, service life of 30-60 years and several fastening methods. In many respects, the duration of the operational period depends on the liability of the locksmith, which mounted the coolant or water supply system.

    Pipes made of metal plastic consist of several spherical layers (as a rule, out of five). Each such layer performs its tasks: clutch, fixation, strength or insulation. Features Specifically, metal plasticism is the possibility of applying a product for hot water. The aluminum layer, connected by reliable glue, gives rigidity, and polyethylene neutralizes the ability of metal to corrosion.

    Advantages:

    • Eco Clean;
    • corrosion resistance, freezing, condensate;
    • Stability to deformities;
    • low weight, simple delivery;
    • maintainability; Installation of metalplastic pipes
    • Low resistance of the liquid;
    • Easy installation.

    Disadvantages:

    • With a hidden pipeline, fittings are not used (threaded);
    • Low resistance to direct sunlight;
    • Without high-quality isolation when freezing inside the water, the system cracks.
    • Product quality is often determined by the price.

    There are 3 regulated GOSTS, according to which the product of the application is determined, their technical qualifications: 18599-2001 - pressure, GOST R 53630- 2009 - Pressure multi-layered for heating and hot water; P 52134-2003 - pressure of thermoplastic layers, high-strength.

    Application area

    Installation of metalplastic pipesPlastic and metal, combining positive qualities, allowed to use products in different directions:

    • heating;
    • internal and outdoor water supply systems;
    • Transportation of poisonous liquids, liquefied gas;
    • compressed air supply;
    • cable protection;
    • Ensuring watering systems.

    Installation of metalplastic pipesPreparation Before assembly work is a compilation of a plan and development of a scheme, in which it is important to specify the placement and connection of points to the plumbing devices - a washing machine, boiler or counters.

    Before starting work, the tools are collected, the preparation of products is carried out:

    • cutting at the desired length;
    • The deformed end is equal to the calibemer;
    • Clean the end with a file.

    Further, depending on the selected installation method, work.

    Mounting begins with the installation of ball valve cranes. To do this, ball valves are selected, working at a pressure of up to 60 atmospheres and at 150 degrees.

    Instruments

    1. Scissors.
    2. Cutters.
    3. Trubores and pipe bending. Installation of metalplastic pipes
    4. Crimp pincers.
    5. Calibrator.
    6. Fatheck.

    A set of necessary tools depends on the selection method. Often for work with your own hands (for example, the fastening of heating pipes from the boiler) only the cutter, crimping pliers and calibrator, will be required.

    Compression compression fittings

    The feature of the application of the compression compound fittings is simple installation without the use of tools that are rented.

    Fitting is a detail of a different shape, size connecting pipes of different and / or single diameter. The components are the fitting, carved ring and nut. Compression fitting guarantees connection strength using a wrench.

    Connection process by compression fittings:

    1. The product is aligned so that the smooth period of the cut and after was at least 10 cm.
    2. On the markup, the pipe is cut off at right angles.
    3. Cleans the end to the scan, and the caliber takes off the incoming chamfer.
    4. Wear a cape nut.
    5. Dress on a precipitated nut split ring.
    6. Moisturize the fitting.
    7. The pipe is installed on the fitting so that its end completely lightened to the edge of the fitting.
    8. The cape nut manually screws up to the stop.
    9. The nut is reached by the nut until the moment when one or a pair of threads is visible, but hacking nuts are also unacceptable.

    Installation of metalplastic pipesAdditionally carry insulation so that the condensate does not settle down. For this, wearing polyethylene corrugated hoses, cut along and strengthen them.

    The marking is different in the external diameter and by the type of fitting thread: Nipple with a thread 16 × ½ (internal) is the definition of an attachment of a metal-plastic pipe with a diameter of 16 mm, and on the other hand, pipe fittings with a thread ½ inches are mounted.

    Press connection

    For the connection, press fittings will require experience in firing. Choosing press fittings, take into account:

    1. Weight - made of brass are harder, better.
    2. Quality - Cheap components will not provide a uniform connection.
    3. Marking - clear, deep and without missed signs.

    The advantages of the method:

    1. Reliability. Press fittings guarantee a uniform and dense pipe connection, and the finished wire is allowed to lay under concrete into the warm floors.
    2. Simple installation for newbies.
    3. Small material costs, since the method does not require the use of expensive tools, work is carried out independently.

    Installation of metalplastic pipesMethod disadvantages:

    1. The need to apply a press tick.
    2. A single use of press fittings does not allow repair work if you need to replace the connection, disassembly them together with the pipe.

    Connection of metal-plastic pipes with their own hands in stages:

    1. It is measured and cut off the desired length of the segment of the product with special scissors.
    2. Removed by a facecreaker internal chamfer.
    3. Removed in the same way external chamfer.
    4. Calibrator diameters are checked.
    5. The sleeve is removed from the fitting, the ring and gaskets are checked.
    6. The sleeve is inserted back into the fitting.
    7. The pipe is mounted. At the same time, if everything is done true, the pipe is visible in the hole of the sleeve.
    8. The sleeve is inserted into the fitting, it is connected to a safe handle.

    Push Fit Connection

    Installation of metalplastic pipesPush Fit is plastic elements made from polyphenylsulfone - "PPSU". It has high strength, frost resistance and long service life. Some firms use distinctive production materials. For example, Henco Vision from Henco from the company from Belgium is based on a polyvinylidenefluoride or PVDF.

    Push fittings are used for:

    • gaskets of metalplastic / polyethylene water pipes;
    • Installation of warm floors;
    • Installation of heating pipes.

    Push Fit installation with your own hands:

    1. Cut by pipe scissors on the markup of the required length.
    2. Calibrate pipe ends.
    3. Dress up on the push fittings pipe to the control opening on the fitting housing.
    4. Another component of the system from the other end of the fitting is inserted.
    5. Pipe is fixed.

    Fastening to walls

    Installation of metalplastic pipesThe vulnerable place of metal-plastic products is low resistance to mechanical damage due to the fact that the aluminum layer is thin.

    With a large radius of bend or constant pressures, the pipe is deformed. In this case, it is recommended to fix the pipeline on the solid base - wall, ceiling or under the plinth. To do this, fastening the wall of the fixing element:

    The fastening process and fixation occurs simply by the method:

    • Fixed support in the wall is fixed in a fixed position;
    • A tube is inserted into a clips with a slot mechanism. If the clip is deaf, the pipe is inserted initially, and then the whole design is attached to the wall.

    When attaching, be sure to use soft gaskets between the fastening element and the pipe.

    Installation of metalplastic pipesThe bends and turns during the installation of the water pipeline or gas are practically in any room. However, you need to know how to correctly generate a metal-plastic product.

    With a valid bend, the inner part of aluminum is deformed, which leads to an unsuitability of the entire system.

    Several fold methods:

    1. Manually . If the pipe diameter is less than 20 mm, you can manually bend the product, not exceeding the bend radius more than 30%.
    2. Springs . Used for medium hard pipes. For work, a tight spring is selected without a perspective breakage. A wire is mounted to one end, then it is dyed inside the pipe to the place of bending. Spring and bending centers must match. The product smoothly grows with the use of the knee stop. After flexing the spring is removed.
    3. Cut wire . The internal laying of segments of solid, but bending the wire is performed. In this case, the length of each segment is no more than a third of the entire length of the pipe itself. The pipe bending is performed, then the segments of the wire are removed.
    4. Sand . If there were no spring or the necessary wire, the heating and falling asleep method is used. To do this, you need to sleep the pipe with sand, close the ends on both sides, so that when the sand is bent, it is not poured. Fill the pipe with sand, fix in vice in the right place of bend, heat this place with a hairdryer and slowly bend.
    5. Machine Volnov . It consists of handle, roller and roller-template, brackets and curved pipes. The pipe is inserted into the machine, and bends to the desired level of inclination.

    Installation of metalplastic pipesIn situations where for some reason, the pipe bending occurred where it is not necessary, many owners are interested in how to lift the pipes. To do this, it is worth considering features:

    1. The angle of irregularity. If you need to align the pipe after purchase when it was in the coupling, then for this you do not need special tools, when installing it is aligned. If the angle of inclination is more than 30 degrees, then in this case, the alignment is impossible.
    2. The thickness of the aluminum layer. With a thickness of 0.2-0.3 mm deformation when aligning cannot be avoided. With a thickness, more than 0.3 mm apply heating and gradual alignment.

    If it is necessary to align the pipe from metal plastic, it is better to use the use of fittings. The alignment of the shader handle does not apply on a problem area, because a crack will appear in the bend, the pipe will flow.

    When using old fittings, the seals are replaced.

    Extension

    Installation of metalplastic pipesIn situations where it is necessary to lengthen the pipeline, adapters or so-called fittings are applied.

    The use of such devices allows you to lengthen the total length of the pipeline to the required distance. Depending on the needs and tasks, such types of fittings are used:

    • Adapter of the Tsang-Nut, Canga-Fitting or Cangu-Tsang;
    • Corn Tsang-nut, Tsang-Nutrition or Tsang-Tsang;
    • Tee Tsang-Naka / Fitzer / Tsang;
    • Tee three collet;
    • Cross;
    • Tsang-nut pressure / two collet nuts.

    Connection methods

    Methods for connecting pipes with increasing similar to the specified options. Apply both fittings and compression connecting elements.

    Non-standard connection

    Installation of metalplastic pipesNon-standard types of compound include variants of lengthening of pipelines made of metal-plastic pipes using the RUSH FIT system. The scheme also differs if the extension or extension in the wall is required.

    For example, the plumber incorrectly calculated the distance of the pipe in the wall to the watering can be in a shower, and it is located below from the required level by 20-40 cm. Since the wall is already closed, and I don't want to repair again, you need to look for options, how to lengthen the pipe without drilling the wall .

    In this case, the connection is applied by pressing. In-block connection in this case is the best option, since when the temperatures drops, the clamps will diverge, and over time, to deform, and the pipe is planted. If we take into account the fact that the wall find a leak is much more complicated, then crimping when laying pipes under the tie - mandatory procedure.

    Example Water supply system

    The layout scheme is conditionally divided into two options - tee or consistent and collector.

    Sequential (tee) scheme

    Installation of metalplastic pipesThe scheme consists of a central pipe that connects consumers of cold tap water. In parallel, hot water flow is mounted in the same method.

    The main pipe has the largest diameter, because it performs the function of the collector. The connection is made by tees therefore the name is tee.

    The principle is simple, ensures the organization of water supply in apartments. The advantage is a slight amount of pipes used. Disadvantages - a system suitable for small apartments, since the longer the system, the smaller the water pressure will be at the end or at the top of the pipeline. Problems with a tee system occur in the case when the crane or a tank breaks, because at the time of replacing plumbing overlap the water completely across the apartment.

    Connection locations in the tee system are hidden under decorative trim without access to the system. If the leakage occurs, it will be difficult to determine its place. Often, the repairs dismant over the rearmen, break the panels.

    Collective scheme

    Installation of metalplastic pipesThis scheme is the best option for large modern apartments with lots of plumbing. The feature of the option is the presence of a collector, in which water from the central riser is fed to the collector, and then to the consumer. Consumer connection is carried out separately.

    Benefits:

    1. Uniformly distribution of water, in which the number of connected devices does not reduce the pressure in the pipe, and the length does not affect the operation of the plumbing.
    2. The possibility when breakdown a plumbing device, turn off only it, and not all together.
    3. Personalization of the characteristics of the plumbing system for a specific device. To do this, install filters, gearboxes.
    4. The flow of water is adjustable if necessary to a larger or smaller side.

    Installation of metalplastic pipesDisadvantages:

    1. Material costs in the installation phase.
    2. The number of water pipes.
    3. The complexity of the system: before connecting the collector, you need to coordinate the project.
    4. Separate instrument is needed if the hot water supply in the apartment is determined centrally.

    Between the collector and the central riser put water pipes with a locking crane. This is necessary for overlapping water supply if necessary. Depending on the tasks, a coarse cleaning filters are installed on the segment of the water supply system, an emergency protection unit. On large spaces, a combination of collector and teete-laying is used.

    After installing the collector, pipes are supplied to the plumbing device individually: to hot or cold water. Additionally put filters, gearboxes, and a shut-off valve for overlapping the water of a separate object between the collector and the plumbing point.

    Repair or partial replacement of metal-plastic pipes with their own hands is a simple task when complying with the requirements of installation and fastening of such a material. The arranged pipeline is easy to dismantle, do not need to be painted. Pipes are light and plastic, do not be corrosion, durable. It is only worth deciding on a safe installation option.
