DIY plastic heating repair

In detail: do-it-yourself plastic heating repair from a real master for the site my.housecope.com.

Unfortunately, the equipment and communications of water supply, heating and sewerage can be damaged during operation. Plastic pipes are no exception. This happens as a result of a violation of installation rules or the use of poor quality products due to the desire of the homeowner to save money. Repair of plastic pipes, like other work, requires knowledge and skills, which will be discussed in the article.

Why does these products get damaged? It depends on the following factors:

Improper use of plastic pipes, for example, if a product that is intended for indoor installation is mounted outdoors or underground.
The technical characteristics of the material are not taken into account - a product for cold water is used as a heating pipe.
The use of low-quality products and connection elements, fasteners.
Freezing of water in pipelines due to violations of insulation and location above the freezing point of the soil.
Rigid pipe fastening without taking into account the coefficient of linear expansion at high water temperatures.
Plumbing in places of high mechanical stress without additional protection - under highways, etc.

Regardless of the type of damage, plastic pipes cannot be repaired with old ones

in a proven way that is used in steel products - the temporary installation of the bandage using pieces of rubber on small holes. In this case, it will be necessary to replace the pipe section by installing additional connections and fittings.

It is also unacceptable to heat the plastic material on an open fire such as a gas burner. Despite the fact that all types of plastics - polyethylene or polyvinyl chloride - melt at temperatures above +140 degrees, joining or sealing a small gust in such an artisanal way will not bring results.

The nature of the repair of a plastic pipe depends on the type of damage:

complete rupture or partial damage to the product;
the occurrence of small-sized water leaks;
squeezing due to heavy load;
breakage or leakage at the joints and connections to plumbing devices.

The technology for repairing plastic pipes consists in replacing damaged elements. Before proceeding with the repair, it is necessary to carefully inspect the entire pipeline and determine the place in which the emergency situation has arisen. On close inspection, defects can often be found in other parts of the structure.

The emergency section of the plastic product must be cut out or the pipe must be completely removed if the connection is made using couplings.

A new product should be installed in place of the damaged pipe.

Repair of plastic heating and water supply pipes must be done with the system turned off, since water will not allow quality repairs to be carried out.

The connection of parts of the pipeline can be done in two ways:

using welding;
using additional couplings and fittings.

To connect products made of polypropylene and polyethylene by welding, it is necessary to cut the pipes evenly and clean the cuts from burrs and irregularities. If the products are of the same diameter, then the butt method can be used. In this case, it is necessary to withstand a certain time, which is determined in the table of the instructions for the welding device, and cool the seam. If it is even and uniform, you should go to the connection of the second part.

It is important that no water, sediment and sand remain inside the pipe, which can make a poor-quality joint. Therefore, before welding, the sections of the products must be thoroughly cleaned, and, if necessary, degreased.

After repairs, the operability of the pipeline should be checked by short-term water connection and again inspected for leaks. Then you can safely enjoy the benefits of civilization.

Repair of plastic water pipes can be done using electrofusion welding. To do this, the sections of the products must also be cleaned of water and dirt, and beveled with a sharp knife.

The products to be connected must be inserted into the sleeve, inside which there is a spiral. When the electric current is turned on, it will heat up and melt the material of the fitting and pipes. After the connection cools down, check the product for operability and the absence of other damage.

When performing this operation, it is very important that no moisture remains inside the products, since when heated it is converted into steam, which will disrupt the quality and reliability of welding.

If the hole in the pipe is small, then you can not change the section of the product, but make repairs using a special reinforcing plastic lining, which must be wrapped around the damage and melt it with a welding machine. The thermal reaction will seal the hole.

Then it is necessary to test the pipeline with water supply and observe the restored section for 5-10 minutes. If there is no leak, then the pipeline must be connected to the water supply system.

If a leak occurs at the point of connection with the fittings or at the point of connection to plumbing fixtures, then it is necessary to carefully inspect the pipe and, if a malfunction is found, disassemble the fitting and tighten the connection again. If the clutch is defective, it should be replaced with a new element. If plastic pipes are damaged, repairs must be done by building them up or installing a connecting fitting of a longer length.

A similar situation may arise at the point where the polyethylene pipe is connected, which is connected to the pumping station. If this unit is not installed correctly, strong vibration will occur, which may damage the coupling or pipe. Therefore, the station must be installed on shock absorbers or a rubber cushion, which will damp the mechanical vibrations of this heavy device.

The main thing when repairing plastic pipes is not to repeat the mistakes that led to the creation of an emergency on the pipeline.

The repair of plastic pipes may often be required if consumables of insufficient quality were used during the installation of the pipeline, or if the installation of the network was carried out unprofessionally.

In any case, it will take some effort to restore the pipeline to work. We will show you with our advice and recommendations how to avoid the same mistakes.

Damaged plastic pipe

Repair must begin with an external examination and diagnosis of the damaged area. The quality, speed and cost of future repairs will directly depend on the type of defect.

There are several main types of damage to plastic pipes:

Full or partial pipe rupture.
Local damage.
Crumpled plastic pipe.
Occurrence of leaks in various pipeline reins.

Consider the features and methods of eliminating each of these types of damage.

Although plastic for the most part surpasses cast iron and steel pipes in technical and operational characteristics, it is still far from the most resistant material in terms of strength to external shock effects.

Like leaks in pipeline nodes, this type of damage occurs most often, while it has the following features:

The occurrence of ruptures is usually associated with careless work carried out near the location of the pipeline route.
For example, the outer pipe can be accidentally caught by an excavator while digging a trench nearby, a domestic-type plastic pipe can be damaged by a heavy object falling on it, etc.
The predisposition of pipes to accidents of this type is explained by the lack of measures that would provide for the protection of pipes from external influences.

Repair of plastic pipes in this case includes the following:

The emergency section must be replaced with a section of a whole pipe, the working pressure of which is comparable to the working pressure in the pipeline.
When repairing the pipeline, the section is arranged by means of two electrically welded couplings.
Mechanical fastening couplings can also be used. They are usually used in highly complex installations such as underwater installations.

Plastic pipe repair technology

The use of electro-welded type couplings, as a rule, is cheaper, while the quality and reliability of such a connection is almost always higher.

Local damage is understood as a defective hole in the pipe, the diameter of which does not exceed 50 mm.

Eliminate local damage in the following way:

Prepare the pipe and the place of damage for repair - dehydrate the pipe and clean it.
An electrowelded plug (reinforcing plate) of the appropriate size is prepared, which will be cheaper in comparison with replacing a section of a plastic pipeline or using two electrowelded couplings.
The lining is welded over the damage.

When a plastic pipe collapses, often no special measures are required to eliminate it. Deformation of a pipe is not always an indication of a violation of the integrity of the pipeline.

This is often caused by local mechanical factors, eliminating which and returning the pipe to operation, the plastic pipe will eventually level out under the influence of internal pressure and its own rigidity.

If the collapse is not eliminated on its own and at the same time interferes with the normal flow of the working fluid, the collapsed section of the pipeline will need to be replaced.

Remember that the presence of scratches or cracks on the pipe surface, the depth of which is more than 10% of the total wall thickness, indicates the need to replace the section of the plastic pipe.

Plastic pipes: repair by applying electrofusion to the damaged area

Causes of leaks:

Most often, at the joints of pipes and pipeline nodes made of plastic, it occurs not due to damage to pipes and nodes, but due to violations of the technology for making welded joints.
Typically, a leak is the result of an unsuccessful repair and appears almost immediately during testing (trial commissioning of the pipeline).
The reason for this may be, for example, the water supply not completely shut off in the pipe during the welding of electrofusion couplings.
A leak at the junction of the plastic pipe connection indicates that gross mistakes were made during the butt welding process.
In addition, leaks can occur if inappropriate materials were used during the construction of the pipeline, both in quality and in technical characteristics.
For example, when inspecting an outdoor pipeline requiring repair, one or more compression fittings may be found buried in the ground, while plastic pipe fittings of this type are designed exclusively for outdoor use.

The method of eliminating a leak in a pipe is to repeat the repair, only in accordance with all the rules and technology.

Welded connection of elements of a household plastic pipeline

A clean and dry pipe is the key to successful welding (soldering) of plastic pipes.Only with mechanical methods of connecting pipes, water can not be an obstacle. If it penetrates into the welding zone during heating, then steam is generated, which creates excessive pressure, which, in turn, can lead to a violation of the fusion of the plastic, which will make the connection of insufficient quality and unsuitable for use.If it is not possible to completely shut off the water flow, simply loosen the bolts at the flange connection of the pipe with the valve. In this case, water will flow into the well, and not into the pipe cavity.To make the need to repair plastic pipes as rare as possible, it is necessary to initially correctly perform pipe connections and pipe laying. In addition, the materials used must fully comply with the operating conditions of the line.Modern, reliable and practical plastic pipes are an excellent solution for arranging a plumbing system in the country or in a private house. Their advantage is quick installation and low weight of the pipeline system, convenience of modernizing the system and repairing pipes. The disadvantage of plastic pipes is that a poorly welded joint inevitably loses its tightness, and the pipes themselves (with the exception of reinforced ones) are weakly resistant to mechanical damage.

Any type of plastic pipe can leak

Wet pipes, the appearance of water droplets similar to dew in the area of the fittings, or a sharp drop in pressure in the system directly warn the owner that it is time to pay attention to the plumbing system and fix the problem with his own hands. If the leak is not eliminated in time, then even a small trickle of water can cause a lot of harm, falling on electrical appliances, power lines or new repairs of neighbors living one floor (or even several floors) below.

To repair a plumbing or heating system made of plastic pipes, you need minimal practical skills and a set of special tools. A simple repair of a plastic pipe with your own hands is quite within the power of an amateur, and for a professional it will not be difficult at all to repair a leak that suddenly appeared.

Important! The main task of the installer-repairer is to choose the most optimal way to eliminate the malfunction, and eliminate the leak as quickly as possible.

The appearance of moisture on the pipes may indicate a depressurization of the system.

The first action to be taken by an installer engaged in the repair of the water main is to turn off, if possible, the water supply to the system, or to the area to be restored. After localizing the leakage area or stopping the water supply, you can start restoration work. Next, the best option is chosen, how to eliminate the leak in plastic pipes. Mandatory conditions - the leak must be eliminated in the shortest possible time, and the detected pipe crack or hole must be repaired as efficiently as possible.

Important! It is imperative to shut off the water supply in front of the area where the leak is detected. In a multi-circuit system, in order to eliminate the leak, it is enough to turn off the water supply directly to the circuit being repaired, and also shut off the diverter valve of the local section of the water supply system.

The most common problem with plastic water pipes is the loss of tightness at the joints of the pipes. Leaks occur for various reasons, depending on the pipe installation option, the type of fittings used and the skill level of the installer, for example:

The most reliable way to repair a damaged line is to replace the damaged section with a new plastic pipe that is securely soldered through fittings to the main system. But it is not always possible to implement the method of high-temperature connections, and then other methods are used to repair the pipeline.

With the help of a clamp, you can quickly eliminate water leakage

Clamping clamp. As a temporary method to stop the leakage, clamping straps are used. By supplementing the clamp with screw clamps with a layer of waterproof plastic material, it is possible to almost completely eliminate the leakage. The good thing about the method is that the water will flow freely through the plumbing system. It is faster and safer than just sealing or sealing a leaky pipe. This repair method does not require shutting off the water supply, the only drawback is the inevitable weakening of the clamp attachment points over time and the loss of the tightness of the connection.

Cold welding. Before covering up the leak in plastic pipes, it is necessary to prepare the required amount of the component for work: thoroughly knead the required amount of the substance in your hands, or mix in the proper proportions. Apply to the damaged area, carefully seal the crack on the pipe and wait until the composition has completely solidified.

Adhesive bandage. A pair of clamping clamps in conjunction with a material impregnated with an adhesive (two-component adhesive + rubber for polypropylene pipes or bandage + cement for sewer pipes) will help you quickly eliminate the leak with your own hands. Advantages: the water supply does not need to be shut off. The disadvantage of this method is that it is forbidden to use an adhesive bandage for systems with high pressure.

Adhesive (sealing) tape. Not a bad option for a quick repair if there is no way to cover a small hole with a sealant. The tape is applied to the damaged area in several layers.

Adhesive pipe tape can be used as a temporary but fairly reliable measure.

Special sealant. This is another quick method for fixing leaks at the junction of a plastic pipe. But this is rather a temporary solution than a quality repair.

Important! Any of the selected methods of restoring the tightness of a section of the water supply system or pipe joints requires preliminary preparation of the pipe itself. The pipe is degreased, cleaned, if necessary, the joint of the future joint of the pipe and fittings is processed.

There are three types of sealing compounds:

neutral type of sealant, suitable for all types of pipes, applied with a mounting gun;
acidic sealant, but it is not used on fragile pipes and on pipelines transporting acids;
silicone sealant is a universal composition, used to seal the socket joint at the junction of sewer pipes.

In the case of heating systems, which can also be assembled from polypropylene pipes, it is somewhat more difficult to eliminate the leak. As a rule, part of the system is laid using the flush-mounted method, and before gluing plastic pipes that were accidentally damaged during construction work or failed naturally, it is necessary to determine exactly where the pipe is flowing in the mounted system. And for this you need to dismantle the decorative panels or, in the worst case, open the wall covering.

Heating is different. It makes sense to describe a number of properties. Not a complete list: on solid briquettes, gas, autonomous electric, economical and wasteful, geothermal, infrared, alternative, water,. It is unrealistic to imagine a comfortable life in a mansion without heating. How to understand what kind of heating is needed for our home? Heating is firmly embedded in the lifestyle of residents as the exclusive cause of thermal energy in winter.

Polypropylene pipes have become popular for a long time as an element of the heating system. And it is not surprising, because polypropylene perfectly withstands both the high temperature of the coolant and the pressure present in the system. But, nevertheless, when installing the heating system, you should take into account the type of polypropylene pipes that you want to use and the availability of the necessary connecting elements on the market. Prices for heating from polypropylene are moderate, but you can make plastic heating yourself.

Installation of a heating system with polypropylene pipes is very common. The reason is quite simple - these pipes have excellent characteristics, they are quite affordable and, importantly, they are absolutely safe for humans.

That is, it is fashionable to use polypropylene pipes not only in heating systems, they are perfect for a centralized water supply system.

Moreover, they can be used equally effectively to supply both cold and hot water. Of course, before using this or that type of pipes for the installation of a particular system, you should first familiarize yourself with their characteristics. What must be considered when installing plastic heating:

specific gravity - the indicator must be at least 0.9 g / cm 3;
limit of fluidity (when stretched) - 25-26 MPa;
the maximum increase in the yield point - 15%;
elasticity at the bend - 850-900 n / mm 2;
impact strength - 22 kJ;
thermal conductivity - 0.24 W / ms;
linear thermal expansion - 0.12 mm / ms.

Basic physical and mechanical properties of polypropylene pipes

Without them, a full-fledged heating scheme from polypropylene pipes is impossible. There are several basic, most commonly used types of fittings (connections):

coupling - connects straight pipe sections;
angle - used to connect segments at an angle of 45 or 90 degrees;
tee - for branching the system.

Connecting elements can be of two types - welded or threaded. The use of this or that directly depends on the use of this element of the system in the future. That is, to connect the meter, it is most expedient to use threaded fittings. But the installation of a polypropylene heating system for the usual joining of two pipe sections can use a welded fitting (soldering plastic heating pipes).

Before proceeding with the direct installation of polypropylene pipes, you should pay attention to whether all requirements are met. In particular, the installation of heating from polypropylene pipes requires:

all parts must be clean, free of chips, cracks and other defects;
the room temperature must be at least 5 degrees.

An important feature is that no threads can be cut on a polypropylene pipe.

Of course, you should prepare in advance not only the materials necessary for installation, but also stock up on the necessary tools. These include a special soldering iron for connecting pipes (electric welding machine for polyfusion welding), scissors for polypropylene pipes, or a jigsaw and a hacksaw.

Soldering iron for plastic pipes

How to make heating from polypropylene with your own hands? Installation steps:

we measure and cut off the required piece of pipe. If a pipe with external stabilization is used, carefully remove the metal layer. This is done to the depth to which the pipe will enter the connecting element;
we clean the pipe cut - it should be perfectly smooth, without burrs;
mark on the pipe the depth of the room in the connecting element. It is important to consider - the pipe should not enter the connection until it stops. It is best to leave a 1mm gap in case narrowing occurs;
before soldering the polypropylene heating, we once again check how smoothly the pipe and the coupling are connected - there should not be the slightest error;
we heat the nozzle of the welding machine to the desired level and at the same time we put the pipe and the connecting element on it. It must be taken into account that all parts must fit tightly onto the heating element. If this is not the case, the selected element should be replaced, since a marriage is quite possible. And this means, and the connection will be fragile.

Heating of polypropylene pipes

after the heating of the elements is completed, they should be removed from the heating element and tightly connected, while the skewing should not be allowed - everything should fully correspond to the marks made earlier. Soldering heating with polypropylene pipes must be of high quality.

According to the same principle, all elements of the heating system should be connected in series.

It is important to remember that if necessary, you can make some corrections in the position of the pipe and the connecting element.

But this should be done extremely quickly, since the time for complete solidification of the seam does not exceed 10-30 seconds (depending on the diameter of the pipe used). That is, if there is an error, it can be corrected - but only very quickly.

Regardless of what type of pipes you use, making the installation of heating with plastic pipes, you should remember that for each type there are certain rules that must be strictly observed.

A video on how to make heating from polypropylene can be seen below.

Now you can ask any questions in our thread on the construction forum.

At the moment, plastic pipes are most often used for the heating system. This is the right choice, since plastic is not subject to corrosion, durable and its installation is much easier than installing steel pipes. But not everyone still knows how to make heating from plastic pipes with their own hands. This is possible if you have a special machine for welding plastic pipes.

You will need:

- welding machine for welding plastic pipes;

- cutter for pipes made of plastic;

Preparatory work

1. Design your heating system and buy everything you need... Draw the system in the form of a diagram, so everything becomes clear, and you can easily buy everything you need. Do not forget to buy shutoff valves or taps that are installed in front of each battery. The diameter of the plastic pipes for heating depends on which system will be used. For a gravitational system, heating pipes will be of a larger diameter. The larger the pipe diameter, the more water or other type of coolant the pipes will be able to pass.

Advice! Do not forget to provide a jumper between the pipes suitable for the batteries - this will allow you to remove the radiators without stopping the circulation in the water system.

2. Mark places for heating radiators... Install them under the window so that the cold, downward air can be heated from the battery. It is best to buy steel or cast iron batteries; also buy reinforced plastic pipes for the heating system. They are reinforced with fiberglass or perforated aluminum for increased strength. The marking of reinforced plastic pipes is PN25.

Heating pipes to radiators

1. Prepare the pipes... Mark them and cut them into the pieces you need with a special pipe cutter. Clean the ends of the pipes from the reinforcing layer.

2. Pipe connection... Soldering of plastic pipes is carried out using a special soldering iron for plastic. It can be bought or rented. Insert the prepared pipe sections into the apparatus, hold them for about one minute, then quickly remove them from the attachments and connect them tightly into each other. In this sequence, weld all elements of the system.

Heating pipes are best installed immediately into the walls. To do this, slit the walls; plastic pipes do not need to be fixed too rigidly.The plastic may play a little when it expands, so leave some free space for the pipes.

3. Connection with metal pipes... It is very common for central heating to connect a plastic system to a metal pipe. There are special fittings for this. They will help to connect the system to the central heating pipe or to the boiler.

Advice! If you do not have forced circulation in the system in, that is, using a circular pump, then mount the pipes at a slope so that the coolant can circulate in them in a natural way.

You can develop and manage the installation of heating system elements made of polypropylene-based pipes on your own. Such heating will be especially interesting for the owners of private houses and all kinds of summer cottages who perform home improvement work on their own.

DIY polypropylene heating

Before proceeding with the installation of polypropylene heating, it is necessary to consider the main advantages of such a solution, choose a heat source, understand the piping schemes, master the basic nuances of installing elements, and then perform the wiring in accordance with the selected scheme.

DIY polypropylene heating

Contents of step-by-step instructions:

High performance of thermal insulation. You can make sure that this statement is correct even without the presence of special devices - just compare by touch the surfaces of pipes made of polypropylene and metal. Polypropylene walls will be barely warm, and metal, other things being equal, may even leave a burn. This confirms that the metal is losing thermal energy.
High resistance to chemical and corrosive influences. This contributes to a significant increase in the service life of polypropylene pipes.

Polypropylene pipes KAN-therm PP Stabi Al reinforced with aluminum

Polypropylene pipes and fittings

Before proceeding with the installation of polypropylene heating on your own, you need to choose a suitable heating source.

If there is a main gas pipeline near the house, you need to buy the appropriate equipment. The best option for arranging a polypropylene heating system is a modern wall-mounted boiler model with protective mechanisms, the necessary pumps and automatic monitoring and control devices.

If you wish, you can abandon the traditional chimney by choosing a boiler model with a closed combustion chamber and a special coaxial tube through which oxygen will be supplied to the unit and exhaust air will be removed from it.

The air exchange pipe can be brought out into the street through the wall of the building, which is a much more profitable measure in financial terms when compared with the arrangement of a standard type chimney.

Electric boiler Proterm

If electricity will be used to heat the house, then it is best to buy an automated heating boiler equipped with a pump, the necessary safety equipment, and an expansion tank.

It is easiest to cope with the installation of such a heating system on your own.

If it is planned to use various kinds of solid fuel for heating, it is necessary to correctly approach the development of a piping scheme for a heating boiler in order to avoid many mistakes. At the outlet of the heating unit, the coolant temperature reaches about 1000 degrees, which imposes a number of additional requirements for the installation of the heating system.

There are also options for arranging heating systems using other energy sources, however, in the case of installing polypropylene pipes, it is better to refrain from using them.

Choose the optimal pipe layout for self-installation of polypropylene heating.In the future, you will receive recommendations on how to connect individual elements and carry out their placement in accordance with the selected plan.

The easiest method for arranging a heating system. In accordance with this wiring method, each battery installed further from the heating unit will be heated to a lower temperature than the previously installed battery.

This method makes it possible to reduce the consumption of materials for the arrangement of the heating system. However, the heating efficiency will be low because the temperature distribution with such a pipe layout is uneven.

In view of this, one should try to refrain from a one-pipe wiring diagram.

More materials will have to be spent on arranging a heating system according to this scheme, however, the main operational properties of such heating will be much higher.

The distribution of heat throughout the premises will be carried out fairly evenly and efficiently.

The most optimal method for arranging a heating system. Pipes are laid in the floor or in the walls of the house around the perimeter. Two-pipe heating is best suited for heating a home. Therefore, experts recommend giving preference to this particular pipe routing option.

In the process of installing a heating system from the pipes in question, you may need to connect plastic elements with metal-plastic pipes. When performing such work, make sure that the diameters of both types of pipes match each other.

Connections of polypropylene and metal pipes to each other

Stick to the following pattern:

for connection to metal-plastic products 20x2 mm, use polypropylene pipes measuring 25x4.2 mm;
to pipes made of metal-plastic with dimensions of 16x2 mm, it is necessary to connect polypropylene pipes with dimensions of 20x3.4 mm;
to metal pipes with dimensions of 26x3 mm, polypropylene pipes with dimensions of 32x5.4 mm are connected.

If the pipes are laid to the batteries in the house from the main pipeline, and the wiring is carried out in accordance with the two-pipe scheme, it is necessary to lay a polypropylene pipe measuring 20x3.4 mm.

The use of pipes with a larger diameter does not make much sense. It also makes no sense to use radiator valves larger than 1.2 inches. Therefore, the statement that with an increase in the diameter of polypropylene pipes and thermostatic valves it becomes warmer in the premises, is not true.

To ensure the required performance of the heating system, it is important that the supply pipe between the boiler and the very last battery is no more than 25 m long. In this case, the boiler output must not exceed 12 kW.

Thus, in order for, for example, a heating system with pipes measuring 20x3.4 to work as efficiently and correctly as possible, it should include a maximum of 6 batteries, 10 sections each.

If it is necessary to connect a larger number of batteries, it will be necessary to increase the length of the pipes for their installation, which will negatively affect the uniformity of heating of the batteries installed at a greater distance from the heating boiler.

Installation of heating from polypropylene pipes and aluminum radiators

However, if you cannot refuse to connect more batteries or increase the length of the pipes, equip the heating system using pipes of a larger cross-section. For example, 32x5.4 mm. Connect 26x3 mm metal-plastic pipes to them.

There is also another option for solving this problem - instead of one heating circuit, you can equip two.

Before proceeding with the work on the arrangement of heating, read the basic recommendations for connecting the elements of the system.

To connect the pipes, as already noted, a special soldering iron is used. It is most convenient to do this work with a partner.

Soldering iron for soldering polypropylene pipes

Instructions for self-soldering polypropylene pipes are extremely simple. It is only important to prevent overheating of the ends of the mating elements and to have time to rigidly fix fittings and polypropylene pipes within ten seconds after their connection.

Previously, it was noted that polypropylene pipes normally tolerate defrosting of the heating system. However, it is important to remember that in addition to pipes, the system also includes expansion tanks and, of course, a boiler, and they can already break when the system is defrosting.

Brazing technology for polypropylene pipes

Prepare a wiring diagram for the system, installing batteries, connecting the boiler in advance. In the future, you will perform all the necessary work in accordance with this scheme.

Directly work on the installation of pipes is carried out in a few simple steps.

Welding time table for polypropylene pipes

Soldering machine for plastic pipes

Calculate the layout of polypropylene pipes.

Calculate the length of the pieces of polypropylene pipes at each section of the heating system. Install the appropriate type of fitting.

Determine the required time to weld the joints. It depends on the diameter of the pipes used and is specified in the relevant reference literature. Bring all the elements of the heating system into the room beforehand and let them warm up to room temperature.

In accordance with the calculated data, mark the cutting points of the pipes using a marker.

Make a cut with special scissors. Cut perpendicular to the surface.

Shears for cutting polypropylene pipes

Wipe the sections with an alcohol solution, remove any dirt with a dry cloth.

Take a nozzle for a soldering machine corresponding to the diameter of the cross-section of the pipes, degrease it, and then install it horizontally and let it heat up to 265 degrees.

Place the pipe and fitting in the holes of the heater, select the required heating time from the table and directly heat the elements to be connected. After that, carefully remove the products, insert the pipe into the fitting and hold for the required time. It is better not to touch the connected elements until they have completely cooled down.

In a similar way, solder all pipes of the heating system, focusing on the drawings you have. Connect the pipes to the heater and radiators according to the drawings.

To prevent the pipes from sagging in the future, ensure their frequent attachment to the surface using clips. For a polypropylene system, the optimal coolant temperature is 60 degrees.

Follow the recommendations received, and your propylene heating will serve flawlessly for many years.
