Contacts; Mayaw Tel; 13920571957 landline; 022-29919888 Fax; 022-29915666 Features health, no chemical reaction, reliable health properties, is a green building materials. Corrosion, not scaling. Using homogeneous melt connection, convenience province installation. Light weight, high strength, good toughness, good impact resistance. Products inside and outside the walls of smooth, water resistance, low transmission fluid system power consumption. Thermal insulation, thermal conductivity is only 1/200 of metal pipes for hot water pipe heat loss is minimal. Heat capacity, long-term normal operating temperature of 70 ℃, short-term use of high temperature up to 95 ℃. The normal life of up to 50 years.
