Unfortunately, communication equipment and water supply, heating and sewage systems may be damaged during operation. Plastic tubes are no exception. This occurs as a result of incorrect installation or use of low-quality products from a desire to save the homeowner. Repair of plastic pipes, as well as other work, requires knowledge and skills, which will be discussed in the article.
Why is the case of products of data corruption? It depends on the following factors:
The use of plastic pipes for other purposes, for example, if the product is intended for indoor installation is mounted on the street or underground.
It does not take into account the technical characteristics of the material – as a heating pipe is used the product for cold water.
The use of low-quality products and connection elements, fasteners.
Freezing water in the pipes due to violations of insulation and the location above the frost line.
Rigid fixation of pipes without consideration linear expansion coefficient at high temperature water.
Laying of water pipeline in places high mechanical loads without additional protection – for highways, etc.
↑ TYPES OF DAMAGES COMMUNICATIONS
Regardless of the type of damage to the plastic pipes can not be repaired the old rubber band for plastic pipes is not podhoditispytannym way, which is used in steel products – setting a temporary bandage using rubber pieces on small holes. In this case, the need to replace the pipe section mounted via additional connections and fittings.
It is also impermissible heating of the plastic material in the open flame of a gas burner type. Despite the fact that all kinds of plastics – polyethylene or polyvinyl chloride melt at a temperature above 140 degrees, or sealing compound in such a small gust of thumb will not result.
The nature of the repair of plastic pipes depends on the type of damage:
complete rupture or partial damage to the product;
appearance of small-sized water leaks;
compression due to a heavy load;
breakage or leakage at the joints and connections to sanitary devices.

Remedy emergency situations when using plastic pipes
Plastic pipe repair technique is to replace the damaged components. Before the repair, you need to carefully examine the entire pipeline and to determine the place in which you create an emergency situation. Upon closer examination, you can often find defects in other parts of the structure.
Emergency portion of plastic products to be cut or completely remove the pipe, if the connection is made by means of couplings.
In place of the damaged pipe should supply a new unit.
Repair of plastic pipe heating and water must be done when the system is off, as the water will not be high-quality repairs.
The connection parts of the pipeline can be done in two ways:
by welding;
with additional couplings and fittings.
To connect products from polypropylene and polyethylene by welding must be precisely cut and to clean the pipe sections from burrs and irregularities. If the product of the same diameter, it is possible to use a method of butt. It is necessary to withstand a certain time, which is defined in the instruction table welder and weld to cool. If it is smooth and homogeneous compound should proceed to the second part.
It is important that the tube does not remain within the water, sediment and sand, which can make low-quality seam. Therefore, before welding it is necessary to thoroughly clean product cuts and degreased, if necessary.
After repair, check the pipeline efficiency by briefly connecting the water and again inspected for leaks. Then you can safely enjoy the benefits of civilization.
Using electrofusion welding repairs
Repair of plastic pipe can be performed using electrofusion svarkiRemont plastic water pipes can be carried out using electrofusion. To do this, slices of products also need to clean the water and dirt, chamfer sharp knife.
The coupled products should be inserted into the sleeve, which is located inside the spiral. When the electric current, it heats up and melts the material of the fitting and the pipe. After cooling, the connection need to check on the performance of the product and the absence of other injuries.
When doing this, it is important that no product remained in water as it is converted when heated into steam, which violates the quality and reliability of the welding.
If the hole in the pipe is small, you can not change the product site, and repair with a special plastic reinforcement plates, which must be wrapped around the injury and welding machine to make it melt. As a result, the thermal reaction the hole is patched.
Then, the test pipe water supply and for 5-10 minutes should be observed for the restoration of the site. If the leak is not present, the pipeline must be connected to the water system.
If leakage occurs at the connection with fittings or at the connection to the sanitary devices, you need to carefully inspect the pipe and when a fault is detected disassemble the fitting and tighten the connection again. If the clutch is defective, it should be replaced with a new element. When damaged plastic pipes – repair should be done by means of their capacity or the installation of a greater length of the connecting fitting.
Such a situation may occur at the connection point of the polyethylene pipe, which is connected to a pumping station. Incorrect installation of the unit there is a strong vibration, resulting in the coupling or pipe could be damaged. Therefore, the station need to be installed on shock absorbers or rubber cushion that will extinguish the mechanical vibrations of the heavy device.
The main thing in the repair of plastic pipes – not to repeat the mistakes that led to the creation of an emergency in the pipeline.
