Recently, communications made of cross-linked polyethylene have gained immense popularity, since this material is relatively inexpensive and has a number of significant advantages: an optimal combination of strength and flexibility, resistance to high temperatures, chemical compounds and destruction. The decisive role in the long period of operation is played by high-quality work on the bonding of all the constituent elements. The assembly of such structures is a fairly simple process, however, it has certain features and important points, the knowledge of which will make it possible to install pipes from cross-linked polyethylene with your own hands without any particular difficulties.
Modern shops present to the customers a huge selection of products intended for equipping communication systems of private houses and apartments. However, Rehau brand pipes occupy a leading position in this market segment. With their vast experience, German suppliers have specialized in the manufacture of high-quality consumables for quite a long time, which allowed them to acquire a solid reputation.
The manufacturer named as the basis for such pipes was chosen the usual thermoplastic polymers with a linear structure of molecules. The only difference from competing products is the optimum elasticity of the elements, which gives the joints the required tightness. However, to perform high-quality installation of Rehau pipes, the use of welding machines operating at extremely high temperatures is required.
Connection of polyethylene pipes is carried out in three ways:
An important point in determining the optimal type of connection is taking into account the pressure of the future communication system, since the first type of fastening can withstand up to 2.5 atm, the second - no more than 6 atm, and the third - almost unlimited .
Before working with pipes made of cross-linked polyethylene, prepare the following set of tools and consumables:
All connection work should be started from the collector outlets. This will thoroughly ensure the complete tightness of the system and easy installation of the elements, since Rehau products bend easily. At the time of purchase fitting fittings pay attention to those types that are designed specifically for the type of pipes. Along with this, it will be useful to protect the future system from condensate or heat loss, depending on the expected temperature of the carrier.
Before installation, it is necessary to fix the pipe made of cross-linked polyethylene with double brackets included in the kit, since high elasticity will prevent the preservation of the specified shape.
Each type of connection has its own characteristics and a slightly different procedure:
Before stretching the fitting connector, never his preliminary analysis and any manipulations to increase the reliability of the contact.

The procedure for connecting pipes made of cross-linked polyethylene on its own is quite simple work, however, high-quality installation requires certain knowledge and some important features are taken into account. In order for the erected communications system to serve for a long time it will be useful to study as much as possible all the information available in the public domain, focusing on the practical advice of professionals.
