PP-R Water Supply

Pp-r pipe appears at the end of last century, is a new type of feed water pipe system, its thermal performance is good, long service life, good corrosion resistance, low thermal conductivity, small pipe resistance, pipe connection is firm, and the advantages of cheap, become the world's most ideal family water supply pipeline, utility ratio of more than 60% in Europe and the United States and other developed countries, utility ratio above 90% in China. At the same time, its performance with excellent health brought health to all users of water. According to authoritative data show that this kind of composite material aging period of more than 50 years, by the national chemical building materials test center testing qualified. Which never scale, never rust, never leakage, green advanced feed material.
