Product Feature 1.Sanitary and innocuous: This product belongs to the green construction materials and can be used in purified water pipe system. 2.Heat resistance:The water temperature in the pipelines can reach 95 degree in the regular long-term continuous work pressure. 3.Erosion resistant and free from deposition: Free from deposition in the pipelines,basins and bathtubs. 4.Heat preservation and energy saving: The coefficient of heat conductivity is only 1/200 less than that of the metal pipes. Our pipes are better to use in heat preservation and energy saving. 5.Light and intensive: 1/8 less than metal pipes and the pressure resistance test can reach over 5MPa(50kg/cm2), with good toughness and being shockproof. 6.Pleasing appearance: With smooth inner and outer coat, small flow resistance, soft color and pleasing appearance. 7.Convenient and stable installation: Thermal welding connection without filaments, completing a joint connection in a few minutes, adopting high quality copper inserting parts to connect metal pipes and water machines, being safe and stable. 8.Service life: Above 50 years in normal operation.
