Soldering plastic pipes - devices and tools for connection. Step-by-step instructions: how to solder plastic pipes at home how to assemble a soldering iron for plastic pipes

Imagine the situation: it is necessary to urgently solder two plastic pipes. Water runs straight out of it, and you need to urgently save the situation! But how to solder plastic pipes? Especially if you do not have practice. The article describes a detailed process how to solder correctly.

The most effective and "painless" option: Call Masters-Plumbing to the house. The option may also be the most reliable, but seriously hitting the owner of the housing, and for the pride of the "peasant in the house" too.

So this option will notice and learn to solder correctly - then the wallet is full of crispy bills, and the man in the house itself was repaired!

Preparation for the process. What instrument need to be needed

We cover the water and go to the plumbing shop (if you have no needed everything you need to repair the water supply)!

So, our task: you need to solder two plastic pipes for water supply.

What instruments and materials need? How to solder plastic pipes?

1. Device to solder plastic pipes. Explain to the seller in the store, for which you need a welding machine, and he will gladly pick you up the desired option.

Moreover, buying an instrument for soldering will be at times cheaper of the plumbing call home, and this is how we remember - one of the fundamental options to select an independent solution to the problem of pipe connection!

Such an instrument for soldering will allow you to make the right repair of communications in the house!

1. A sharp knife or pipeline. It will take you to cut pipes and cutting the edge so that the surface of the connected ends is perfectly smooth. It is possible to use a special device - pipe cut.
2. Slim File, Fillet, Perhaps fine-grained sandpaper. It will be needed to stripping the ends that we will solder, to the perfectly smooth surface.
3. The fitting / coupling is a small tube that you wear on both ends of the pipes that we will solder (also purchased in the plumbing store).
4. Roulette.
5. Fatheck.

So, everything is ready for installation - proceed! Just do everything right!

The first step and, perhaps, the most important thing - prepare the necessary elements for soldering.

Preparation of soldered elements

At first, gently cut the snap-knife tube to the length you need. You can use special pipe cutters if it is in your home arsenal or suddenly found in the workshop.

Then cut the burrs at the ends. Burzes - a thin shavings of plastic, jar on the ends of the tubes. Since the combined surface should be perfectly smooth, it is gently with a knife with a knife remove.

After that, the ends of the plastic tubes are cleaned. To do this, we use a thin file, a feet, even the rifel can be (in this species of the appliance, the working surface is specially curved, which allows you to clean the surfaces inside the tubes, etc.).

You can also try to make sweeping by fine-grained emery paper. Do not forget the important rule - the surface after stripping should be smooth, not rough, so do not spare your strength and clean the ends of the plastic tubes are good, bringing them to the ideal!

Now we perform the same cycle of events and for fitting, if it is homemade and is just a piece of the tube that you will use for soldering.

If the fitting or coupling is purchased in the store, their surface inside (which is needed to us for the connection) should already be smooth and necessary size.

So, the pipes are ready, the fitting is ready.

Getting to spawn

Now let's start directly to the spike surfaces. This requires a device for soldering plastic pipes and, directly, the billets themselves. The most important thing here is to follow the heat heating temperature for soldering so that it is optimal for your billets.

Temperature modes for pipes of various diameters are presented in a special table, and it is necessary to follow it. By the way, the soldering device usually warms up the nozzle to the required temperature.

True, on old, early versions of instruments for soldering such a function, there is no, so you have to adjust the temperature manually.

Be sure to handle the workpiece before the connection itself. Be sure to clean the surface from contamination, degrease with alcohol.

You also need to take chamfers from blanks. To do this, you need to use the halter and alcohol. This operation is necessary only for those pipes that were previously reinforced by aluminum or other composition.

Modern devices for soldering plastic pipes have a variety of designs, and some of them are able to significantly reduce your time required to perform an operation.

For example, on some solders it is possible to install multiple nozzles - up to 4 pieces.

In other words, you can warm up two pipes and two fittings at the same time, and after bringing to the required temperature for a short time to create a rather large design.

The compound itself must be carried out as quickly as possible to prevent the system's tightness reduction. As soon as you see that the elements of the workpiece are warming up to the required temperature, then immediately remove the blanks from the nozzles and proceed to the connection.

The correct compound must be made very dense, in the future in the system of heating or water supply, leaks did not happen.

Check joint connection after spike

As a result, two plastic tubes for water supply tightly connected! Did we do everything right? You can judge this only after a while, when let the water on the "new" water supply.

After soldering pipes with the fitting, do not hurry to open the valve tap: after the entire procedure of your own repair, there should be at least an hour.

If, for some reason, you still conducted a cold room procedure, where the temperature was lower than the room, then it is worth waiting for at least two or three hours before the trial start of water. Here the main thing is not to rush, and everything is done correctly, so that your works do not go to the pump.

In the end stage of the installation, you must make sure that the place of the soldering is quite reliable. To do this, it is best to carry out a test start of water. Open the crane. After starting the water, carefully inspect the entire fixed by you, the renovated water supply unit.

If there are still a divorce on the designs or on fitting / clutch, the water wakes up, dripping or even shoves the jet from under the new connection, then your operation to save the home water pipeline, is not correct!

It should be either anew to carry out the entire repairs procedure, or after all, to upset and call the Masters-Plumbing Master. If everything went fine, and water runs only from the crane, as it should be, we congratulate you with success!

The mission is fulfilled, the family is pleased, plastic tubes for water pipes are securely and tightly connected! As can be seen now, this operation is not impracticable, and if you follow the usual registration truths, you can achieve the desired result!

Now you can safely challenge a new repair, as you already have enough knowledge, and you know how to solder plastic pipes correctly!

How to solder plastic pipes for water supply right?
How to solder plastic pipes properly - what a tool, preparation, spike process, checking the connection places, which device for soldering to choose what ...

Modern repairs with the replacement of the water supply system and the heating system are unthinkable without the use of plastic pipes. Rapidly broken into the building materials at the end of the twentieth century, polypropylene plastic pipes made a coup in the history of water supply and firmly occupied their leading position.

About how to solder plastic pipes from polypropylene and replace them with their own hands, we will tell in this article.

Pipeline heating from polypropylene pipes

In modern life, plastic pipes are used absolutely in all areas, increasingly becoming indispensable in the construction and repair of any scope due to their significant advantages over other materials:

• do not corrosion,
• have high chemical resistance
• sustainable microorganisms,
• have low heat and sound conductivity,
• light weight and convenience during transportation,
• eco-friendly
• easy to install
• suitable for external and hidden gaskets,
• durable - warranty period of use of 50 years, subject to the correct mode of use.

Proper mode: Plastic Polypropylene Pipes withstand the operating pressure to 15 bar at a temperature of from 0 to 10 degrees and 2 bar at high temperatures (95 degrees).

Arsenal of fittings and corners of polypropylene

Due to its environmental friendliness, this type of pipes is successfully used in hot and cold water supply and home heating. And the diversity of fittings with brass and chrome inserts makes it easy to combine with existing reinforcement from steel and any subjects of plumbing.

Necessary equipment

For a pipeline device for water supply or heating, pipes are used with an outer diameter of 16 to 63 mm, for the connection of which the flarified (coupped) welding is used.

For high-quality installation, small:

1. Soldering iron with nozzles of various diameters.

How to choose a soldering iron for plastic pipes so that the installation was fast and high-quality? The assortment of soldering iron is great and diverse as the pricing policy.

Soldering iron with a set of teflon nozzles

• The power of the soldering iron is of great importance. For applications in household conditions and diameters of pipes 16-63 mm, power will be sufficient up to 1200 W.
  With the power of 1800 and more WT, the performance of the soldering iron allows you to apply it in professional activities. But the newcomer is not needed with a small speed of work.
• Nozzles are heating elements and consist of a sleeve that pays the outer surface of the end of the pipe and Dorn, which melts the inner surface of the terminal part.
  Nozzles must have a non-stick teflon coating. Usually, complete with a soldering iron goes 6 nozzles of different diameters.
• It is more convenient to use a soldering iron with the possibility of installing not one, but three nozzles. This will save considerable time when replacing the nozzles from one diameter to another, because To replace them, you need to cool the soldering iron, and then warm it up.
• The soldering iron of the professional series is equipped with electronic adjustment of temperature controlling the heating of the nozzle with an accuracy of 1-5 degrees. You can do without temperatures without adjusting the temperature, acquiring a thermometer to measure the temperature on the nozzle.

It is important not to exceed the nozzle temperature of 260 degrees, in which the spike of polypropylene occurs, and at 270 degrees plastic loses its stability and begins to superfluous, the pipe will not enter the fitting.

In case of insufficient heating, the part may not reach the necessary viscous plasticity and the diffusion of the material will not happen. As a consequence, the unreliability of the connection.

1. The second necessary tool for installation are special plastic scissors.

1. In addition, you will need a roulette, a pencil, a tarp rod, as well as the pipes and fittings of the required size.

Operation of the soldering iron

There are several rules how to use a soldering iron for plastic pipes.

The soldering iron is installed on a flat surface and the nozzles of all necessary diameters are fixed on it with special keys. Closer to the edge put the nozzle needed for soldering directly on the wall.

Mounting process

Phased instructions, how to solder plastic pipes will help you produce high-quality and fast installation.

1. Cut scissors cut off the pipe perpendicular to its axis.
2. We select the fitting of the desired size.

Note! Not preheated fitting should have an inner diameter of a little smaller external diameter of the pipe.

1. We clean the fitting socket and the end of the pipe from dust, degrease the soapy water or alcohol and dried.
2. We establish the connected parts to the appropriate soldering iron nozzle: the pipe is inserted into the sleeve to the full depth of welding, the fitting fever is put on Dorn.

Combine pipes using a soldering iron is quite easy

To everyone who plans to independently perform the installation of sewage, water supply or heating systems, it is worth dealing with how to solder PVC pipes, PPE, as well as copper products. The creation of all-in-block connections allows to achieve maximum tightness, while having mastered the technology, it is possible to work quite quickly.

Since I had to master the method of soldering a variety of products, practical information and observations in this industry at one time, I had accumulated enough. All the advice that I will give in this article will be based on them.

Pros and cons of soldering as a way of mounting

When designing pipelines for heating systems, water supply and sewage systems, different methods of connecting parts are used, ranging from simple docking using sealing elastic rings and ending with welding pipes.

The soldering technology is approximately in the middle between these extremes - both in complexity and in terms of the reliability of the resulting compound.

Having mastered the technique, you can create enough complex systems

The benefits of soldering as a way of installation, from my point of view, are:

1. Technology allows you to create a deline connection with a high level of tightness.
2. At the junction of two pipes, the strength of the walls is reduced slightly, which is very important when designing and creating pressure pipelines.
3. The method of soldering most materials does not require the use of complex expensive equipment: Of course, without a soldering iron / gas burner, but still work with them much easier than with gas or electric welding.
4. Also, an obvious advantage is saving on fittings: Coroluses, tees, Signs and other parts intended for soldering have an extremely simple design, because they are relatively inexpensive. The benefit becomes obvious if we compare the cost with the cost of press fittings for metal-plastic pipes.

Plastic fitting for in-block connection

The sake of justice should be told about the minuses:

1. The compounds, as I specified above, are absolutely obtained. This means that to access the lumen of the pipe, we will have to cut it, and then - restore integrity. And since at the same time the detail length will inevitably decrease, then the instruction is usually recommended to completely replace the damaged area.
2. To perform work, special devices are still required, as well as (if we solder copper) fluxes and solders. Rent / buying equipment and purchase of consumables can seriously affect the budget of the entire project.

Copper fittings are quite expensive

However, even with these shortcomings, the technique remains quite universal, especially since, in contrast to welding, it is quite possible to cope with their own hands. Of course, the skill is needed, but it may well be replaced by a thoughtful study of the recommendations that I will give below, as well as a small practice.

Plastic soldering

Equipment for work

When we make contours for water supply or drainage, understand how to solder propylene tubes, you need first. Polypropylene is the perfect material for such a compound, since it is perfectly melted when heated, forming a practically monolithic structure: that is why PPE pipes are often used to assemble pressure networks.

You can solder plastic pipes: metal-plastic products are not intended for such an installation, so they need to be connected in expensive fittings using a special tool.

Soldering iron for pipes with a set of nozzles

For connecting parts, a special tool is used - soldering iron. Dozens of different models can be found on the market, but almost all of them have an identical design scheme:

1. The base of the soldering iron is a housing inside which the heating element is placed.
2. The heating system connects to the network via the power cable and is controlled using a special regulator (there is not all models, while in cheap species can issue a difference with the real operating temperature at 10-200, which is sometimes critical).
3. To the heating element to connect nozzles for pipes and fittings. As a rule, a soldering iron is equipped with several sets of nozzles, which allows working with pipes of the most undercut diameters.

When choosing a soldering iron to connect pipes from polypropylene and similar materials, it is necessary first of all to pay attention to power. Professional models have a capacity of 1.5 - 2 kW.

But it seems to me that there is such a productivity for domestic use. When choosing power, it is best to navigate the maximum diameter of the pipes with which you will work:

Many people make a decision to make a water pipeline by their own hands.

Practice shows that for this purpose, PVC-based structures are best suited. And to do everything , soldering skills will be required..

It is not worth worrying if you experience the use of the soldering iron is minimal or absent at all. Soldering pipe PVC - The process is not too heavy, and it is not necessary to prepare special tools for it in large quantities.

Materials for work

To spend competently welding work, you need to prepare such set of tools:

• marker;
• construction level;
• roulette;
• welding device for plastic pipes;
• scissors for cutting materials from PVC.

Almost all of the above can be found at home or purchase in the store at a modest price with the exception of the welding machine. If he is missing, and the need for it is only one-time, then you can rent it or ask you for a time.

Soldering device

Before finding out how to solder plastic pipes, you need to study well how the soldering iron is arranged for their cutting, and what kind of principle it works. This the welding machine is designed to connect the plumbing structures From plastic, and equipped with a special sole, which has heating elements.

To make it easier to work, such a sole most often includes holes with different diameters, which attach special nozzles to solder pipes. Due to the thermostator, the temperature indicators of the device are adjusted. Such a thermostat is on the body of the soldering iron, and the power supply is turned on or off with additional switches equipped with light indication. It is still equipped with a handle comfortable for work, as well as a stand so that the device can be placed on a flat surface with stationary use.

Rules and techniques of PVC pipe soldering

Soldering of plastic or polypropylene water pipes It should be carried out strictly in a certain sequence. It looks like this:

Pipes should be soldered with many indicators, give them below:

So, the soldering technique looks like this:

• take the special scissors on plastic and with their help cut the pipe of the desired size;
• with the use of alcohol composition, clean the place of connection of pipes from fat and dirt;
• retractor and piping put in the nozzle and warmth during the time that corresponds to the parameters of the material;
• after heating, the part is connected to each other, the pipeline insert into the socket;
• at the end of the work, see the weld to be high quality. Plastic rings should appear in the joints of the joints.

So, we have already found out, as properly with the use of the soldering iron, discharge plastic water pipes. But remember that the installed water supply can work for a long time and without problems, it is recommended to comply with some recommendations.

First of all, during operation, be sure to note that the device on the device has a Teflon coating, which does not allow the appearance of Nagara. After each use of the device (after welding) be sure to remove the wooden blade. It is forbidden to remove them after cooling the nozzles, as this may deform the coating, as well as cause a breakdown of the device.

It is possible to carry out the primary welding in five minutes after the welding soldering service will warm up, and if it comes to connecting reinforced pipes, you need to remove the shader two external design layers:

• aluminum;
• polypropylene.

And only then the elements can be connected according to the technique.

All types of welding work should be carried out exclusively at the positive ambient temperature.

And last - all work needs to be performed confidently, all elements need to be placed on one axis. If the connection is made poorly, it will be necessary to cut off the node and weld it again.

Special attention should be paid to the installation of such fixed elements as:

• taps;
• fitting;
• valves;
• tees;
• adapters.

Quality of welded connections It may be bad if you do not comply with the rules of elementary security when working with welding equipment. Take into account all the above rules and recommendations so that your plumbing is set efficiently and quickly, and then could serve for many years.

For those who know how to solder plastic pipes, the arrangement of the heating system, hot or cold water supply and other domestic pipelines will not be too complicated. The assembly of such systems requires primarily a reliable connection of pipes, which determines the quality of all the work done.

Photo 1. Soldering tip design for plastic pipes.

Weld them from various types of plastic is not so difficult as it may seem. Polypropylene, polyethylene and other polymeric materials are quite compatible in operation, do not require too complex equipment, the melting point is much lower than that of iron, weight is relatively small, as well as rigidity. But knowledge of the specifics of each material, about what and in what sequence is necessary.

Required tools and materials

Welding of polypropylene pipes with their own hands requires a certain set of tools and materials. It makes sense to briefly list them at the beginning and figure out what and for what is intended. So, to weld pipes efficiently, it is necessary:

• special soldering iron or household soldering iron;
• set of nozzles for such a soldering iron;
• a secateur (scissors) designed to smooth pipe cutting;
• plastic pipes;
• connecting couplings (fittings) of various types;
• adapters for threaded compounds;
• shaiver;
• carrier;
• means for degreasing plastic pipes.

How to solder polypropylene pipes? This question is asked beginner masters. In photo 1, it can be seen that the design of the soldering iron is quite unusual. It is intended to heat plastic, if more precisely, the pipes of a certain diameter. After all, the installation of plastic pipelines is basically welding the components. Such a soldering iron is an analogue of the welding machine used to connect steel products.

The soldering iron nozzles are designed to work with pipes and fittings of a small or large diameter. Usually they are sold in the form of a set.

Instead of scissors for cutting plastic pipes, it is quite possible to apply the usual hacksaw for metal. But then to get a smooth slice at right angles will be quite difficult and the process of cutting itself will take too much time. The secret of even a person without special skills will cut the tube smoothly.

Plastic pipes are welded by almost the same technology, but there are some differences. PVC, polypropylene, polyethylene, for example, different melting point. There are also reinforced pipes that need to be cleaned from the reinforcing material before welding.

Couplings, or fittings, connecting elements of various purposes. For example, fittings for connecting threaded compounds, called American women, tees, corners with different bend angle, conventional connecting clutches, etc. As you can guess, the inner diameter of the connecting elements is approximately equal to the outer diameter of plastic pipes.

Sheer is a tool designed to clean the reinforcing layer, which is located on top. If this reinforcing layer is internal, a carrier is already needed for cleaning it.

In order for the connection to be more durable, the soldering place must be preventing it. For this, the compositions dissolving fat, ethyl alcohol or others are used.

In addition to the instruments described, the construction level, special markers, etc., may be needed. But they will be needed when the real assembly is carried out, for example, heating systems.

Step by step description of the welding of polypropylene elements

As an example, it is worth describing the process of compounding polypropylene pipes. They are most common, used in a reinforced and unarmitted form for the arrangement of almost any home pipeline systems.

The technology of welding polypropylene pipes, as already noted above, is based on a relatively small melting point of the source material. Actually, this is the basic property of polypropylene or other plastic, which determines the relatively low cost of mounting pipelines.

When soldering pipes, the source material for the manufacture of which is polypropylene, it is necessary to do the following steps:

1. Cut pipes with the required length using special scissors. The quality of the cut and its angle in relation to the axial line of the pipe must be carefully checked.
2. Pick up fittings, taking into account their purpose and diameter.
3. Degrease the pipes and fittings that will be welded. The pipe should be deguted from above, fitting - inside.
4. Turn on the soldering iron, equip it with nozzles of such a diameter that is needed for pipe soldering. It should be borne in mind that the soldering iron heats up long enough, so you can include it in advance. Its operating temperature is in a specific range, there is a regulator to configure to configure to set the position to the desired type.
5. If welding of reinforced pipes is carried out, it is necessary to pre-clean the connection location from the reinforcing layer. To do this, a carrier or shaver is used to be prepared in advance.
6. Insert the pipe into a soldering iron cooked for her. Fitting on the nozzle to wear, as it will warm his inner side. The heating time depends on the parameters of pipes and fittings, which will be discussed below.
7. After the heating is completed, insert the pipe into the fitting, making it up to the stop. You need to carefully control the angle of inserts so that the connection does not work uneven. On each pipe and on each fitting there is a special strip in the form of a convex profile, which indicates the direction of welding. If such strips of soldering one opposite the other, even a rather complex system from the pipes will be in the same plane.
8. The time of welding polypropylene pipes is a few minutes, so they must be postponed until complete hardening, after which it is already possible to start mounting on the wall.

As you can see, spend the welding process is not so difficult. But in fact, it is necessary before the real use of knowledge acquired from the material setlined slightly practice. Training will not cost too expensive, as unarmed pipes and fittings are cheap enough. A mistake in real work will lead to the need to start all over first, spending time and materials.

How to solder polypropylene pipes is already clear, the turn came to figure out with some process parameters.

Parameters that need to be considered when welding pipes

Types of plastic pipes: 1 - polyethylene, 2 - polypropylene, 3 - metal-plastic.

Each plastic melts at a certain temperature, and this must be considered when conducting welding. In addition, there are also such concepts as the recommended operating temperature and softening temperature.

For example, polypropylene melts if it is heated to 175 ° C. But if the temperature is 30 ° C less, the material begins to soften, which leads to an irreversible deformation. With such parameters, manufacturers of polypropylene pipes recommend operating temperature not exceeding 95 °. For pipelines, which moves, for example, boiling water, these pipes are not suitable. But if they are reinforced aluminum or other metal, they can be used for hot environments.

Welding at which polypropylene pipes are guaranteed to be securely connected, can be made only with specific environmental parameters. At least in the room where it is carried out should be warm. No manufacturer recommends this kind of work at a minus temperature. Yes, and the accuracy of human work in the cold - the concept is quite relative.

Conclusion on the topic

An important point is the time of heating pipes and fittings by a soldering iron.

For example, if the thermometers are fixed 20 ° C in the workplace, then for a pipe with a diameter of 20 mm with a width of the welded belt to 16 mm, it is necessary to spend 6 ° C for heating, 4 s to connect and 2 min to ensure that this connection is fully solid.

The table of diameter ratios, the length of the welding and time space spent on the basic operations should be a guide to action for those who are going to weld plastic pipes for various types of pipelines.

Recently, traditional cast iron and steel pipelines are intensively replaced by more modern products of the chemical industry - polyvinyl chloride and polypropylene and pipes. But new materials require other technology connecting pipes, and the most effective in this case is a soldering.

Note! The soldering temperature affecting the quality of the connection depends on the size of the products - this can be seen in the table below.

Step 1. Selecting one or another source material directly depends on future destination. The main criterion of division is the maximum permissible temperature of the working environment. In this regard, it is distinguished by pipes for hot, cold, as well as mixed water supply.

To determine the exact number of necessary pipes and fittings, the room is measured and its approximate plan is drawn up. The latter is indicated by the size of the future highway and all its elements.

After buying all components, you can proceed to the next step.

Stage 2. Required equipment

The principle of the soldering is to heat the ends of the connected pipes to the desired temperature and the subsequent fixation. To do this, you will need a special device - a welding machine.

It can be three types:

In addition to the apparatus itself, it will take:

On the choice of nozzles

Heating nozzles must correspond to the cross section of the connected pipes. To do this, pay attention to certain parameters:

• strength;
• preservation of shape at temperature differences;
• thermal conductivity.

Most welding machines are compatible immediately with several different nozzles, which is extremely convenient when equipping complex highways.

In each nozzle, there are two ends at once - one is intended for heating the outer surface of the products, the other for the inner. All nozzles are covered with teflon spraying, which prevents the molten spraying. The sizes of nozzle fluctuate between 2 cm and 6 cm, which completely coincides with the common and cross-sections of the pipes.

When the plan is drawn up, and all components are purchased, it remains only to carefully remove the room. Particular attention should be paid to dust, because even the smallest particles, settled on the seams, can easily disrupt hermeticity.

Initially, the nozzle is inserted into the socket, after which the device is turned on. Further actions depend on the chosen method of soldering, so consider them (techniques) in more detail.

Method number 1. Diffusion solder

When using this welding techno, the material of the parts connected mutually penetrates each other, and after cooling it forms a monolithic element. One of the most common processing methods, which is nevertheless acceptable only for homogeneous materials.

Note! In this case, the soldering temperature reaches 265ᵒС. It is at such a temperature that polypropylene melts.

Video - Diffusion Soldering PP Pipes

Method number 2. Popper

When welding, welding machines with different cross sections of nozzles are used. The procedure itself looks quite simple.

Step 1. Initially, cuts of pipes of the required length are cut. It is important that the pruning takes place exclusively at right angles.

Step 2. Product ends are cleaned with shader (if reinforced pipes are used).

Step 3. The ends are inserted into the nozzle of the appropriate section, warm up to the melting point and are connected.

Note! It is imperative that when cooled pipes did not change their position.

Method number 3. Shock soldering

This method is advisable when connecting pipes of large diameter. As in the previous versions, the pipes are cut into the sections of the required length, and the ends are carefully cleaned.

Method number 3. Coupling

With a coupling method of welding between the connected elements, an additional part is introduced - the coupling. Heating occurs the same manner, that's just not the parts of the highway, but only the elements of the connection.

Method number 4. Polyfusion soldering

A variety of diffuse technology, characterized in that only one of the two elements connected is melted.

Method number 5. "Cold" soldering PP pipes

This welding method provides for applying a special adhesive composition on the connected pipes. It is characteristic that the use of "cold" welding is permissible only in those highways in which the pressure of the working fluid is slightly.

When overheating or connecting pipes of a small diameter, the risk of influxing on the inner surface occurs. These influx will prevent the free movement of the working fluid during operation.

To avoid this, it is necessary to check the connection for such defective sites. The connection site must be thought out, and if the air is free to pass, then the welding unequivocally came out very high quality.

Note! After that, it is necessary to check the tightness of the connection - for this, a small amount of water is passed through the paved elements.

Important rules for soldering polypropylene

For a high-quality and sealed connection, you must follow certain rules.

Soldering PP pipes in difficult areas

When asked, what is the main problem when arranging a plastic pipeline, any specialist will answer: soldering in hard-to-reach places. To perform this procedure, the design is divided into several sections.

First of all, an uncomfortable large plot is mounted. It is advisable to form it separately, and then install it in a stationary place.

After fixing the problem area, smaller and, accordingly, simple elements are installed in the installation. This event needs to be held at least two.

RESULTS

Skills in soldering PP pipes will come with time. There is nothing complicated here, although at first a few couplings and one or two dozen meters of pipes will be spoiled. And it is not scary, because they are not so expensive; At least autonomy from plumbing costs more.

Polypropylene is a popular material that is widely used in many construction and assembly areas. And the water supply is no exception. Polypropylene highways are distinguished by corrosion resistance, long service life, good thermal conductivity and tightness. The last criterion depends entirely on how correctly the soldering of plastic pipes is carried out. And you did not hear. Polypropylene, in contrast to polyvinyl chloride, it is necessary and you can simply solder into a single design using a special welding machine for polymers.

About how to use the iron (so in the circles of craftsmen they call a soldering iron for plastic) and how to fasten the water supply system correctly, in our material below with a detailed video instruction.

Important: Before making a decision on the installation of water pipes from polypropylene pipes, it is worth find out that this material under the influence of high temperatures is inclined to stretching. That is, if using polypropylene pipes for a highway of the DHW, then such communication can simply be supplied over time. Therefore, for hot water, it is necessary to use only aluminum polypropylene tubes.

In order to follow the instructions, to solder the entire system of the water supply system with long-term operation, it is advisable to understand what kind of pipes the master works. After all, polypropylene is divided into four categories, each of which is intended for use under certain conditions. Failure to comply with the instructions on the operation, there is no effort of the master, and the plumbing will eventually fail.

So, polypropylene pipes are four types:

• Tubes with marking PN 10 . The thin-walled small diameter material designed for use at temperatures up to 45 degrees. Can be used in a hard floor system or warm floor.
• Tubes with marking PN 16 . It is worth being extremely attentive. Polypropylene such a category can be used either under conditions of high pressure in communication, but for cold water, or at low pressure in the network with hot water.
• Marking PN 20 allows you to use plastic pipes for a device of any highway operating at a temperature not higher than +80 degrees.
• PN 25 Tubes are the most reinforced aluminum or fiberglass tubes suitable for mounting hot water system. Here, the material can be operated under the temperature of the temperature regime to 95 degrees Celsius.

In addition, it is worth understanding that all polypropylene pipes of any category may have a different color. The kel does not play any difference except black. This color of pipes indicates that PP tuba is strongly protected from UV radiation.

Important: All polypropylene pipes will be generally used only if the ranges in the operating pressure and temperature in the network are observed. The higher the water temperature in the water supply system, the lower the pressure should be, and vice versa.

Pipe soldering machine

Plastic pipes can be soldered only with the help of a special tool - soldering iron. The household unit in shape resembles a kind of iron on the stand. Its heating sole (mirror) is able to warm up to temperatures above 260 degrees, which allows to melting (soldering) the polymer for its qualitative connection.

On the heating sole, there are places for attaching nozzles. As a rule, in the household apparatus, 2-3 nozzles can be attached to the sole. Their diameter depends on the configuration, which was originally acquired tool. But most often it is nozzles with a diameter of 16-32 mm.

IMPORTANT: Only pipes, the diameter of which does not exceed 63 mm can be soldered at home. At the same time, they are connected exclusively using couplings and fittings. Larger diameter pipes soldered on professional equipment and most often online.

You can solder plastic pipes with your own hands both with the help of a sword-shaped apparatus and with cylindrical. The quality of the soldering will be unchanged and equally good if you follow the instructions.

Important: work soldering iron with your own hands should be carried out only in heated to the positive room temperatures. At the same time, it is important to know what the cooler will be in the room, the greater the time of heating plastic and metalplastic (in the case of a reinforced pipe).

Preparatory stage

• First of all, it is necessary to prepare the pipeline, marker and roulette. With such tools such tools will be marked with tube and its cuts on individual elements.
• After all the metal-plastic and PVC parts of the future system are cut, it is necessary to thoroughly clean all the places of alleged compounds, including couplings and fittings.

Important: Aluminum reinforced pipe cuts using Shawra. At the same time, before soldering, first it is worth removing the top layer of polypropylene and aluminum. This will improve the quality of the connection. Fiberglass reinforced tubes are soldered as well as standard polypropylene.

For those who do not know how to solder plastic pipes (metal-plastic / PVC) at home with their own hands, it is necessary to adhere to the following recommendations when performing work:

• The process of soldering starts no earlier than 5-10 minutes after turning on the soldering iron. It should warm up to a given temperature.
• Polypropylene tubes with a diameter of up to 40 mm can be successfully soldered on a sword-shaped apparatus. For a larger diameter tube, it is better to use a more professional centering unit.
• After heating the polymer (PVC or metal) on the teflon coating of the nozzles will remain pieces of soft plastic. They are desirable to immediately clean the wooden spatula. It is impossible to read the residues of the polymer on the cooled nozzle or using metal devices. There is a risk of damaging Teflon coating and as a result, spoil the item.

Important: Timely stripping of the nozzle from the residues of the polymer allows you to get a guaranteed even and smooth connection.

Process soldering

So, polypropylene (PVC) elements of the water supply system do it yourself in several stages:

• A soldering iron is installed on the platform and secure it reliably. The device set the desired temperature. For polypropylene it is equal to 260 degrees, for polyethylene - 220.
• On the platform before turning on the soldering iron, the nozzles of the desired diameter are put on.
• As soon as the device warms up, you can take a cut tube and fitting under it and put on the nozzle. Withstand parts in accordance with the diameter of the elements (see Recommendations below).
• As soon as all parts of the pipeline are carefully proper, it is worth firmly and slowly docile items to a dense fit. We leave the intercom from complete cooling. All parts of communication should be cleaned.

Important: After the pipe is inserted into the fitting, it is forbidden to move it and in any way to turn. The polymer (PVC) in the lumen of the pipe can be shrivened and the connection will occur.

After the pipes are fed and cold, you can skip the water or air through them to check the tightness of the connection.

• For a tub, with a cross section of 16 mm - withstand 5 s;
• For a tube with a diameter of 20 mm - heating is 6 seconds;
• Pipes 25 mm - Gray 7 seconds;
• Elements 32 mm - soldering 8 seconds;
• Pipes with a diameter of 40 mm - heating for 12 seconds;
• Tube diameter 50 mm - 24 seconds;
• Pipe 63 mm - 40 sec.

Important Tip: If the wizard for the first time will open pipes from polypropylene (PVC) with their own hands, then it is possible to pre-stretch on unnecessary segments of polypropylene elements. In addition, if in the process of the soldering, flaws were made in the connection, you can simply cut this section of the pipeline and solder a new one.

Tip: Buying a soldering iron for one-time execution of work with your own hands is inexpedient from the point of view of finance. In this case, it is better to take the apparatus for PVC pipes for rent in a specialized construction store.
