Its advantages over PP types 1 or 2 and other thermoplastic pipes in the potable water industries are its high impact strength and resistance to high temperatures. PP-R pipes and fittings are an exceptional alternative for copper pipe, galvanized pipe, UPVC service pipe, PE pipe, PE-X pipe and PE-RT pipe. As it uses random copolymerization technology, which ensures polypropylene intensity and heat resistance, PP-R pipe can be used for transferring 70A C hot water under long-term 1.0 MPa condition with a service life of more than 50 years, making it the ideal plastic pipe for hot and cold water applications. Ever since its invention in the 1980a s, the PP-R pipe has taken a large market share in piping all over the world. It is mainly applied in: Hot and cold water system for buildings, including central heating system; Heating system in buildings, including underfloor, wall panel and radiant heating system; Potable water supply system; Central air-conditioning system;
