Soldering polypropylene pipes without a soldering iron. Methods for connecting plastic water pipes, depending on the material of manufacture How to connect polypropylene pipes yourself without soldering

The ability to assemble pipelines on your own is a definite plus of polypropylene products. Using convenient and lightweight material, you can build a sewer with your own hands, repair and modernize the water supply.

The main thing is to understand the specifics of connecting prefabricated elements to each other. Agree, this is an important part of the work, responsible for the tightness of the line and its trouble-free operation.

We offer you detailed information on how polypropylene pipes are soldered, what equipment is used in the work, and also list the most common mistakes novice welders make.

The information we offer will help to build trouble-free communications. For visual perception, the article is supplemented with graphic applications and a video guide.

The soldering process is carried out due to the pronounced thermoplastic properties of the material. Polypropylene softens when heated - it acquires a state similar to plasticine.

This is what a soldering iron ("iron") for polypropylene pipes looks like. uncomplicated electrical device, semi-automatic, thanks to which plastic soldering is done

For butt welding, the designs of soldering irons are characterized by increased complexity. Usually, such equipment includes not only a heating element, but also a system for centering the parts to be welded.

As a rule, direct welding equipment, like the technology itself, is rarely used in the domestic sector. The priority of use is industry.

A more complex device, which is used to accurately center the parts to be welded with further process heating and soldering. Used with direct welding technology

In addition to soldering irons, the master will also need:

scissors - ;
roulette construction;
locksmith's square;
shaver for pipes with reinforcement;
marker or pencil;
surface degreaser.

Since the work is carried out on high-temperature equipment, be sure to wear thick work gloves.

Polypropylene Welding Procedure

Important warning! Welding work polymer materials should be carried out in a well ventilated area. When heated and melted, polymers are released toxic substances, which in a certain concentration have a serious impact on human health.

The procedure for welding polypropylene is simple, but requires accuracy and accuracy in work. Common mistakes should also be avoided, such as insufficient or excessive heating.

First of all, you need to prepare for work:

Install blanks of the required diameter on the heater plateau.
Set the regulator to 260ºС.
Prepare mating parts - mark, chamfer, degrease.
Turn on the soldering station.
Wait for a set operating temperature– turning on the green indicator.

Mating parts (pipe - coupling) should be simultaneously put on blanks soldering station. In this case, the polypropylene pipe is mounted in the inner region of one blank, and the coupling (or socket of the fitting) on the outer surface of the other blank.

Usually, the ends of the pipe are inserted along the border of the previously marked line, and the coupling is pushed all the way. withstanding polypropylene parts on heated discs, you should remember about important nuance technology - exposure time.

Conclusions and useful video on the topic

Professionals always have something to learn. How to work with polypropylene can be seen in the following video:

Mounting pipelines made of polymers by soldering them “hot” is a convenient and popular technique. It is successfully used in the conditions of installation of communications, including at the household level.

People without experience can use this welding method. The main thing is to correctly understand the technology and ensure its exact execution. A technological equipment can be bought or rented.

Do you have experience in soldering polypropylene pipes? Please share information with our readers. You can leave comments and ask questions on the topic in the form below.

Metal pipes, which were standard in the past, are now increasingly being replaced by plastic ones, or rather, polypropylene (and also PVC). And if a welding machine is usually used to mount the former, then polymer analogues are mounted using a special soldering iron. However, the latter may not be at hand at the moment when it will be necessary to solder one of these pipes. Is there a way out of this situation? Actually - yes. In addition, here we will consider the soldering of wires.

Installation of water supply, sanitation and heating systems;
Repair work on heating and water supply systems;
The need to connect two wires;
Repairing the awning - sealing holes.

Is there an alternative to a professional soldering iron for polypropylene pipes?

Before dismantling the soldering of wires and awnings, let's dwell on the pipes. The apparatus for their welding costs several thousand rubles. Mostly professionals buy it for themselves, but for an ordinary person this device simply will not pay off. In this regard, it is necessary to look for an alternative option, which can become much more common in ordinary houses gas-burner.

Such a burner perfectly shows itself both in repair and in installation. At the same time, it can be soldered as pipes of small diameter, as well as rather large analogues. It is used not only for connecting pipes, but also as a means of installing plastic taps to control the flow of water into the pipeline.

Tips for connecting polypropylene pipes without a soldering iron

The quality of the connection largely depends on the cleanliness and absence of grease on the pipes themselves. Therefore, before work, it is recommended to degrease and clean them from dirt;
All pipes, as well as fittings and other parts must be from the same manufacturer. So you will be sure that the same temperature effect must be applied to connect them. In addition, you should not save on quality. Its absence can manifest itself both during the soldering process and during subsequent operation;
Do not solder in cold conditions. If, for some reason, the temperature in the room has dropped by less than +5 degrees, the connection may be fragile;
It is recommended to practice on unnecessary pipe sections.

Alternative - PVC pipes

Exists plastic pipes, which do not need soldering, since they can be glued together. In addition, they have all-plastic pipe threads located on the inner and outer sides.

In addition, for PVC and CPVC pipes, there is a special solvent-based cement. After treatment with such cement, the surface becomes soft and can be quickly glued.

The procedure for soldering polypropylene pipes

Drafting detailed diagram, marking the places of turns, the location of cranes, corners and other elements of the system;
Pipe cutting. It is best to take with a margin of 25 millimeters, which will be fused onto the fitting;
The pipe and fitting are heated with a burner. The temperature at the same time is approximately 280 degrees Celsius;
The fused elements are held together until they cool.

A universal way to solder an awning

With the advent of the warm season, the need for tents increases. By putting on your local area or taking a small tent for a picnic, you can find an unpleasant surprise- a hole. Is it worth it to buy a new awning after that or can I somehow fix the situation?

For soldering, we need a building hair dryer, which will have a special crevice nozzle, as well as a patch with a roller. After preliminary cleaning of the place of damage and patching of dust and grease, it is necessary to lay the awning on a flat surface. Having attached a patch to it, we begin to heat up both surfaces with the help of a crevice nozzle, simultaneously fastening it with a roller. The better you heat the surfaces, the better they stick to each other. But here it is extremely important not to overdo it and not burn a hole.

Soldering wires without a soldering iron using a soldering tape

Though regular soldering iron found in our homes much more often than its analogue for plastic pipes, it still may not be at hand in right moment when you need to connect two wires. Of course, you can try to twist them and wrap them with “blue electrical tape”, but this option is only temporary. At the same time, you can connect the wires “forever” without a soldering iron.

A special soldering tape will help us with this, which allows you to create a strong polymer layer around the wire, providing a complete connection and insulation. problem area. The steps for working with this tape are as follows:

Stripping the wires that we will connect and their subsequent twisting;
Removing the protective layer from the tape and wrapping around the place of twisting;
Heating the tape with an open flame until it melts and evenly covers the problem area. For this, ordinary matches are suitable;
After the tape has cooled, remove the excess flux. The wire is fully connected and ready for further use.

Welding wires with a special paste

Paste is used to connect various metals such as steel, nickel, copper and others. The reason for this versatility is that this material is produced on the basis of silver. In general, the paste contains flux, solder and binders ground to a state of powder. In the vast majority of cases, this method is used for soldering small wires. So, if your favorite headphones are out of order, and there is no soldering iron at hand, then ideal solution it will be pasta. The way to use it is very simple:

We clean the wires and twist them together;
We apply the paste to the place of twisting as evenly as possible;
With help ordinary lighter the paste is heated until it melts and turns into a full-fledged soldering;
After this place it is necessary to isolate all bare parts of the wire. The ideal remedy for this is a heat shrink sleeve. We put it on the place of soldering, after which we warm it up and get reliable insulation.

Installation polypropylene pipeline so simple that you can easily do it even in between watching your favorite TV shows or series. The main thing is to stick to some general rules and understand the basic principles of joining plastic pipes. I will tell you all this from my own experience.

Installation work

Starting to work with polypropylene pipes, I first of all remembered their main qualities:

The low price allowed me without any abuse of the family budget purchase all necessary plastic products, including connection fittings, with some margin. After all, even having the appropriate experience, no one is immune from making mistakes, and it is better if unsuccessful operation have replacement parts at hand, and not run after them to the store, leaving an unfinished pipeline and an unfinished series;

A simple connection instruction including "hot" and "cold" methods. But simplicity does not preclude the need for the presence of a special tool for each of the options. Next, I will describe in detail both of them, since I used both soldering and compression fittings in different areas. It is better for you to make a choice in advance in order to take care of the availability of appropriate equipment. You can do it right after reading the article;
No corrosive processes. The plastic surface is not subject to either internal corrosion, which can be provoked by the transported liquid, or external, which usually appears after the pipeline is laid in the ground. Thus, when laying an underground water supply, I knew that it would last for decades, but only taking into account the quality and absolute connections.

If you are planning to use polypropylene pipes for the installation of a heating system, I recommend purchasing reinforced samples that can withstand high temperatures, which will eliminate the risk of an emergency.

Based on the foregoing, I purchased materials with a margin, took out the right tools and prepared to make quality connections that can be left unattended for years to come.

hot method

Where I planned to lower the water supply line underground, I had no doubts about the choice of the connection method: only soldering. The melting point of propylene is only 260 degrees Celsius, and after solidification are formed fully sealed seams. In addition, the process itself is quite fast. The impossibility of dismantling me in this case did not bother me at all.

When laying pipelines indoors, welding is also excellent. The only exceptions can be those areas where disassembly of pipes is required, or a situation in which it is not at all possible to get a pipe soldering iron.

If you have a one-time installation planned, then it is not necessary to purchase an expensive welding machine for plastic pipes, it would be more rational to rent it.

Before connecting polypropylene pipes using the “hot” method, in addition to the “iron”, I also prepared the following tools:

Now I will describe to you in detail how polypropylene pipes are connected, you really will have time to install small sections during the period of scrolling commercials on TV:

If this is your first time trying to solder plastic pipes, then I recommend that you first practice on a couple of products that will not be included in the system being installed.
So you "fill your hand" and can avoid typical mistakes when performing "clean" work.

Training:

I AM took out a soldering iron from a suitcase where he was, and placed it on a level and stable oak table. You can put the device on the floor or on the asphalt, the main thing is that it has a reliable position, because you have to deal with high temperatures;

Then inserted nozzles corresponding to the diameters of the elements to be soldered. At the same time, a product is installed under the pipe in the form of a kind of “bowl”, which wraps around its edge with outside, and under the tubular element that enters it and performs melting from the inside;

Turned on the device. If your device has a power regulator, then set it to 260-270 degrees Celsius. If this is not the case, then the unit will automatically heat up to the specified temperature;

Markup. Here I have already moved on to work with the pipes themselves. With a tape measure and a pencil marked out the necessary segments for the formation of the pipeline. In addition, I measured the depth of the heating elements and, adding a couple of millimeters, applied it to the soldering points. This can be done after cutting products. This technique will help you control the immersion of the edge of the cut into the nozzle, since excessive melting can lead to the formation of a bulge in the seam that prevents the passage of liquid;

Cutting. The main thing here is to observe a right angle. Thanks to some experience, I have no problems with this, that is, evenly brought the scissors to the line and made a clear cut with one smooth strong movement. Try also, without excitement, with the necessary efforts to complete the cutting. Otherwise, if you make oblique cuts, you will have to level them with a hacksaw or knife. It is also worth noting that when using reinforced pipes, you must first remove the upper layer plastic and foil laid under it;

Heat. At this stage I I put the prepared coupling on the mandrel, and inserted the pipe section with some delay into the nozzle-sleeve. Why belatedly? Because the walls of the connecting element are thicker, and, accordingly, they will melt longer, that is, the head start will not interfere with them. Keep the products in this position should be guided by the following table:

Docking. After the above time has passed, I removed both fragments with melted edges from the welder and connected, again, strictly at a right angle, after which he held the time indicated in the following table:

Cross section, cm	Connection time, s	Cooling time, s
2	4	2
2,5	4	2
3,2	6	4
4	6	4
5	6	4
6,3	8	6
7,5	10	8
9	11	8
11	12	8

In no case do not turn the connected products at the time of solidification, as this may provoke a violation of the tightness of the seam.

Control. I let water through the finished pipeline and checked all joints for leaks. If you suddenly find one in yourself, then cut out the problem area and weld a new segment in its place.

cold method

Compression fittings allow you to connect polypropylene pipes without soldering. All you need besides the connectors themselves is crimp key, which, as a rule, is sold with them.

The very process of connecting pipes in a “cold” way, I performed as follows, when I didn’t have an “iron” at hand, and it was necessary to restore the damaged section of the water supply urgently:

Measured and cut off the desired pipe fragment;

Calibrated hole. It is very important that its cross section ideally matches the diameter of the fitting tail;

Put on the edge of the pipe ferrule;

Then I inserted the fitting itself inside;

Crimped the clutch with a special key, securely fixing it on the pipe;

I checked the coupling for the presence of characteristic recesses, indicating a quality connection.

The described method also solves well the problem of how to connect metal pipe with polypropylene. To do this, simply select the appropriate compression fitting, in which one of the ends is equipped with a metal thread of the desired pitch and diameter.

If you have a question: "How to connect a HDPE pipe with polypropylene?" Then again, you can turn to compression fittings, since welding here, most likely, will not cope due to the significant difference in the melting temperatures of these materials. At least I wouldn't risk it.

And a bit of fly in the ointment: despite some versatility of the “cold” connection method, it takes much more time to implement. So, if you have to install a long pipeline, then during the time of advertising on TV you may not have time to cope with the task.

Conclusion

A little practice and following the above recommendations will allow you to lay water supply lines from polypropylene pipes, practically without looking up from watching your favorite TV shows and TV programs. The main thing is to be careful and accurate, since a mistake made will take much more time to correct it than timely control of the work being done.

Polypropylene pipes are used in the installation of plumbing, irrigation systems and heating. The popularity of the material and various areas of use are due to its characteristics: strength, durability, ease of connection. An important argument in favor of polypropylene pipes was their price, which is significantly lower than that of metal-plastic or metal counterparts.

Service life of plastic pipeline cold water is 50 years, such an impressive figure makes it necessary to replace obsolete lines with just this type of highways. Joint tightness - the most important factor for any pipeline, therefore, the viability of the system depends on the quality of installation. In the article we will talk about how to connect polypropylene pipes with metal, polyethylene, steel, and also consider various options welding.

Materials and tools

If you decide to save on installation services and do it yourself, then you need to buy or rent a special soldering iron with nozzles. In addition to it, you will need:

tape measure and marker for marking;
scissors for cutting plastic pipes;
pipe cleaning.

There are several types of polypropylene pipes, which differ in the area of \u200b\u200buse:

PN 10, 16 - used for laying cold water pipes;
PN 20 - universal pipes with thick walls, they are able to withstand hot water up to 80ºC, therefore they are suitable for heating installation;
PN 25 is a composite pipe with a metal or nylon layer, which is peeled off during soldering. It is used for heating systems, the final heating temperature is 95 ° C.

A distinctive characteristic of the connection of polypropylene pipes is the absence of joints directly between the pipes. If their diameter is less than 50 mm, all parts can be connected with fittings for various purposes:

couplings - connect sections of the same diameter;
crosses - used to create branches;
plugs - seal the end of the pipe;
adapters - serve to connect pipes of different diameters;
nipple fittings - connect with flexible hoses.

How to operate the welding machine

The principle of connecting the pipeline is to heat the elements and quickly connect them. Household pipe welding machines have a power of up to 1 kW. It is enough to quickly and efficiently heat up the material, but for industrial purposes, more powerful and expensive devices are used. Included with the soldering iron are nozzles corresponding to the diameter of various pipes. The pipe is heated from the outside, and the fitting from the inside.

The work of the soldering iron begins with the inclusion in the network and setting the desired heating temperature, depending on the diameter of the plastic pipes being welded. The average value is 250–270°C. Such heat requires caution, touching a hot part will cause a burn, for safety reasons it is worth wearing gloves.

soldering process

To cut the pipes, a hacksaw or sharp scissors are used that do not deform the plastic. The incision is made at a right angle. If burrs appear on the end, they are carefully cleaned. After cutting, the depth of soldering is marked. You need to measure the section of the pipe that will enter the tee or coupling, and draw a line with a marker. The value of this section depends on the diameter of the pipes, the larger it is, the greater the immersion in the connecting element.

If you have to work with reinforced pipes, the algorithm of actions changes. Before soldering, it is necessary to clean the top layer of the pipe, consisting of aluminum foil, basalt or nylon fiber. Special tool designed to remove the desired amount of layer.

Careful removal of the foil is very important, a small amount of material on the pipe will spoil the tightness of the soldering.

A soldering iron with nozzles selected according to the diameter of the pipes is installed on a flat and solid surface. From both sides, a pipe and a fitting are simultaneously put on the heated nozzle, deepening to the intended line. The heating time of the plastic depends on the size of the pipes: for 20 mm, 6 seconds is enough, and for 32 mm, 8 seconds are required. After maintaining the set period of time, the elements are removed and firmly fixed into each other, while it is impossible to make rotary movements. For a strong adhesion of the joint, it will take from 4 to 10 seconds, during which time the polypropylene will harden and form an integral connection.

Failure to comply with the recommended heating time leads to the formation of leaks - with insufficient heating or sealing of the internal space - with excessive overheating. The resulting flow should not be immediately removed, the molten plastic is more deformed. It is necessary to wait until it cools and cut off the excess.

Without experience, in order to understand how to solder pipes correctly, you can make several training connections. It is convenient to work with short connections by placing the welding machine on the table, in this position you can perform all possible job, and joining a partially laid highway is more difficult. The nozzle of the soldering iron is put on a fixed polypropylene pipe, and a tee is inserted into the second part, while the device is kept on weight. When executing the trunk, you need to monitor the order of the connections being made. Try to avoid docking in hard-to-reach places where it will be difficult to use a soldering iron.

It is important to keep the material clean and dry, because dirt and moisture reduce the quality of the pipe connection. Even a small amount of moisture deforms the material when heated. Chemical composition pipes from different manufacturers may not match, this will lead to leaky docking. It is necessary to buy all the material - pipes and fittings - from one manufacturer.

The temperature in the room where polypropylene is being installed must not fall below +5°C.

Crimp connection method

Docking of the pipeline by soldering is reliable and durable, it is impossible to disassemble it, and sometimes this is what is required for repair. In addition, it is not always possible to purchase or borrow a welding machine; in such cases, they use the method of connecting polypropylene pipes without soldering. For this, fittings with threads and a clamping ring are used. They are called collet or crimp, such a connection is able to withstand a pressure of sixteen atmospheres.

For a mechanical connection, it is necessary to purchase several additional parts: elbows designed for joining various diameters, a tee, solder and combined couplings, having an external and internal thread, plugs, adapters with external thread, elbows and tees with a union nut, ball valves, various fittings with a factory thread.

To ensure tightness, the joints and seals are liberally lubricated with silicone.

To work, you will need a crimp wrench, which can be bought at the same time as the fittings. cutting off desired part pipe, firmly insert it into the fitting, wrap the thread of the element with a thread for sealing and tighten the ferrule and nut, fully tightening is done with a wrench. This connection method takes much more time than welding, but it is convenient for them to connect polypropylene pipes to radiators.

Docking of a steel pipe with polypropylene

When installing heating or plumbing, there are areas where metal and plastic joining is required. The connection of a polypropylene pipe and a metal one occurs when using special adapters. This fitting has a smooth plastic hole on one side and a threaded metal insert on the other. The polypropylene pipe is connected by welding, and the metal pipe is screwed with a key. The resulting joint does not have welded strength, but will serve for a long time.

After complete installation system, it is necessary to conduct a test run of water to check the tightness of all connection points of pipes and other elements. If threaded connections are leaking, they must be tightened.

Self-installation of plumbing or heating from polypropylene pipes is quite a feasible task. For its implementation, it is necessary to strictly follow the instructions for using the welding machine for plastic and the installation technology. To better understand all the nuances of the process, you should watch a video in which experienced installers share their experience.

To connect such pipes, you need to use special fittings. Such a connection is necessary in cases where water was introduced into the house with HDPE pipes, and further water distribution inside the house is carried out with polypropylene pipes. So, there are 2 types of connections:

In the first case, attach a threaded coupling to the HDPE pipe, where on one side there will be a clamp connection, and on a polypropylene, respectively, similar coupling. That's just on one side there will be a solder joint, and on the other - a threaded one. In both cases, FUM tape or tow is used for threading to seal the joint and avoid leaks.
Otherwise, a flange connection is used. Installed between flanges rubber compressor. The flanges are bolted together.

With polypropylene, it is important to know that High Quality when carrying out such work, it can be achieved only when the wall thickness of the products is taken into account. Modern technologies allow you to create quite durable and reliable communications from such pipes. They are not subject to corrosion processes, so they found such wide use. Such manipulations can be carried out in one of several ways, however, work can be classified into two categories:

soldering method;
fittings.

Connection methods

If you decide to find out how to connect a polypropylene pipe to a polypropylene pipe, you need to figure out the methods. For example, thin-walled pipes can be threaded. If you need to equip the supply system cold water, the temperature of the environment in which does not exceed +20 ° C, then products with the marking PN 10 should be used. The same applies to laying underfloor heating, in which the temperature does not exceed +45 ° C.

If it is necessary to arrange a cold water supply system that will be transported when high blood pressure, pipes marked PN 16 should be used. This recommendation is relevant for pipelines with reduced pressure. Most quality option connection is welding, it can be used for PN 20 pipes, which are able to withstand temperatures up to +80 °C. They have thicker walls compared to the previous ones.

The same connection method is also suitable for PN 25 - pipes reinforced with aluminum foil, which are intended for systems central heating and hot water. Pipes with this marking will be able to withstand temperatures up to +95 ° C. Connections may be permanent when welding is used; as well as detachable, in this case a thread is used.

Threaded connection

Before connecting a polypropylene pipe to a polypropylene pipe, you need to figure out which method is best to use. For example, for a threaded connection, you need to prepare threaded fittings, because you need to cut the thread into polypropylene products it is forbidden. The connection is carried out using a special tape, which will make the joint strong and reliable.

Used fittings

If you decide to use threaded connection then you will need:

solder couplings;
triple square;
crosses combined;
couplings;
90° elbows;
combined squares;
ball valves;
soldering squares at 45 °;
plugs;
adapter with external thread;
water outlet;
fittings made of polypropylene with factory thread.

Welded connection

If you are thinking about how to connect a polypropylene pipe with a polypropylene one, then you can use the welded method. However, it is important to consider that the connection will be one-piece. When melting, the molecules of one part move to another, diffusion occurs. From heating by an electric welding machine, the parts are organically interconnected, because they have the same chemical composition.

To carry out work, prepare:

soldering iron;
apparatus for welding;
polypropylene fittings and pipes;

In addition to the listed tools and materials, you should prepare a hacksaw or scissors for metal, a tape measure, couplings like taps, corners and pipes. It is important to stock up on fum tape. As for the apparatus for welding, it will consist of heating element and welding nozzles, the diameter of which varies from 16 to 40 mm.

As soon as the indicator goes out, you can start working, because this will be a signal that the desired temperature of 260 ° C has been reached. This will take approximately 15 minutes. If the temperature is below zero environment, then welding work must be abandoned. If it is necessary to weld pipes with a diameter of 60 mm, use the method socket welding. For a more impressive diameter, butt welding is suitable, which does not involve the use of additional parts.

For pipes whose diameter varies from 16 to 50 millimeters, a hand soldering iron should be used. More impressive diameters will be connected mechanically welding machine. The ends of the pipes should be well heated with removable sleeves, then it remains only to press the elements together, applying little effort. This effect should last a few seconds.

Electrofusion welding acts as a more good option compared to the previous method, because the process is controlled by the program. The quality of the joint will be higher, and the need for fixation will disappear. Devices with electrodes are used to supply voltage to the heater inside the sleeve.

Before connecting two polypropylene pipes using the socket method, it is necessary to cut the products at a right angle.

Next, the master should put a mark on the depth of the socket, to which 2 mm should be added. The connection of products begins with heating with a special device. After the parts are connected to each other. And if polypropylene has an aluminum layer, then the connection can be made through perforated holes. This allows you to significantly increase the strength of the pipe marked PN 25.

Use of butt welding

Before connecting polypropylene pipes to each other, you should think about which method is best to use. Butt welding may be suitable, which will allow you to connect pipes together for outdoor sewerage. This approach is relevant if the pipe wall thickness exceeds 4 mm.

At the first stage, the welding spots should be trimmed to parallelism. After that, it is necessary to carry out heating and ensure accuracy with a centering device. Welding should be accompanied by ventilation of the room, because polypropylene emits carbon dioxide and water vapor, as well as smokes.

Connection without soldering

Quite often, novice home craftsmen are wondering how to connect polypropylene pipes without soldering. For this, fittings made of the same material as the pipes are usually used. If the heating system contains fiberglass reinforced highways, then other types of products will not work.

You should stock up on polypropylene fittings that are reinforced with fiberglass. An exception is the case when there is a need to combine polypropylene with another material. In this case, threaded elements are used, for example, "American". Before connecting polypropylene pipes without a soldering iron, you should ask what fittings can be found on sale for arranging water supply and heating systems, among them:

Y-shaped;
straight;
T-shaped.

It is necessary to use these elements, taking into account the method of application and position. According to the type of connection, several types of shaped products are distinguished, namely:

compression (crimp);
welded.

Compression fittings made of polypropylene are supplied in ready-made, there is no need to collect them additionally. Compression fittings have advantages over welded fittings. They consist in:

ease and simplicity of installation;
no need to use welding equipment;
installation possibilities polypropylene fittings under any weather conditions, because they are not afraid of negative temperatures;
no need for the master to have special skills in installing compression fittings.

If you are thinking about the question of how to connect polypropylene pipes at home using fittings, then you should familiarize yourself with the technology. At the first stage, construction tools are prepared, namely:

gas and adjustable wrenches;
screwdrivers;
open-end wrenches;
sealant;
special scissors;
pipe cutter;
beveler;
caliber.

You can think about the location of the pipes, which can be in the wall or on top of it. The diagram should not have hard corners. Product flexibility is achieved through building hair dryer. If you decide to use polypropylene pipes for heating, you should know how to connect them.

The connection point must be sealed in any way convenient for you. You can do this with fum tape. Then the system is assembled according to the principle of the designer, at the corners and in the places where the flow is distributed into several parts, special elements such as corners and tees should be used.

Conclusion

Now you know how to connect polypropylene pipes with fittings. However, as practice shows, the welded method is more reliable, because diffusion occurs in the process, which ensures the reliability and strength of the system.
