PPR трубы и фитинг

ppr reducing tee Specification: 20mm-160mm. Color:white green gray Very competitive price Good quality, fast delivery, best service UNIENT and Chinese prestigious Tongji University in Shanghai carry out strategic cooperation in the R&D of intercontinental polymer materials. Characteristics of ppr hot waterpipe. 1. Well heat resistance ability The pipes can be used for a long time while the working temperature of water is 158°F(70°c). They can be used for a short time while it reaches 203°F(95°c). The softening temperature is 284°F(140°c). 2. Long life span Under normal conditions of temperature and pressure, pp-r pipes can be used for over 50 years. 3. Little resistance for water flow The inner walls of pp-r pipes increase by over 30% than the metal pipes with the same size. 4. Environmental During the process of production, construction and use, pp-r pipes will not make any pollution to the environment. 5. Healthy The materials of pp-r pipes are formed with just two elements, that is, Carbon and Hydrogen. The sanitation performance of the materials has passed the examination by the government authority. 6. Well corrosion-resistance Except for few oxidants, the pipes can endure the erosion of many kinds of chemical materials. The pipes will not be rusted, get eroded, and breed the growth of bacteria. 7. Solid connection PP-R pipe system adopts the hot-welding way for connection. The pipes and fittings are linked together. The tensile, bending and impact intensity at the interface is bigger than the pipe intensity, avoiding the hidden danger of water leakage. 8. Lightweight, convenient transport and handle, good for labor-saving
