This type of pipe now occupies a leading position in USA and abroad. As raw material for PEX plumbing tubing has long been known in recent years have found wide application of propylene copolymers with ethylene: block copolymers (type 2) and statsopolimer (type 3).
The main advantages of pipes copolymers of propylene is a high impact strength and heat resistance. Pressure pipe cross linked polymer may be used for a long time at a temperature (75-80) ° C and a pressure in the network up to 1,0 MPa and a pressure-free mode of block polymers of propylene tubes capable of withstanding prolonged exposure to temperatures 95oS. Pipes made of polymers of propylene with ethylene retain sufficient impact strength and at low temperatures down to minus 20 ° C.
Tests and experience have already obtained, confirm the reliability of pipelines from the polymers of propylene at the operating period not less than 50 years. Use PEX tubes as versatile as metal, but much more promising. They can be constructed in virtually any existing today of engineering networks: to take stock of drinking water to supply coolant to the radiator, for the diversion of sewage and storm water drainage, irrigation, etc. PEX tubing UV resistant, have excellent sound insulation properties , resistance to fire (you can use during fire fighting), etc. In addition, PEX is an environmentally friendly product, transferring their money on products made from it and ensuring the safety of drinking water.
With the ability to weld PEX, greatly facilitated the process of installing manufactured from a pipe, and the reliability of welded joints – the highest as compared with other methods and approaches in terms of strength to the pipe itself. The prices for PEX plumbing tubing and PEX fittings are much lower than Aluminum. All this, according to leading experts, we can call PEX plumbing pipe and PEX fittings are one of the most promising to date types of pipelines universal application.
