Characteristic
1. Non-toxic, hygienic. Pp-r raw material molecules is only carbon, hydrogen, no harmful and toxic elements exist, it is not only for hot and cold water pipes, but also for pure drinking water systems.
2. Heat preservation and energy saving. The thermal conductivity of pp-r pipe is 0.21W / mk, which is only 1/200 of steel pipe.
3. Good heat resistance. The Vicat soften point of ppr tube is 131.5 鈩? The maximum working temperature can reach 95 鈩? which can meet the requirements of hot water system in building water supply.
4. The service life of ppr tube can reach more than 50 years under the condition of working temperature 70 鈩?and working pressure PN1.0 Mpa, and it can serve more than 100 years working on normal temperature (20鈩?.
5. PPR has a good welding performance, pipe and pipe fittings can be connected by hot melt and electric fusion, and the strength of the connecting part is greater than the pipe itself.

Application
1. Cold water system for buildings
2. Purified water supply system that can be drank directly
3. Central control air conditioner system
4. Transport or discharge of chemical media etc. Industrial piping systems
