2013 hot sale PPRCT stop valve
Features:
1. Well heat resistance ability
The pipes can be used for a long time while the workingtemperature of water is 70°C. They can be used for a short time while it reaches95°C. The softening temperature is 140°C.
2. Well insulation ability
3. Long life span
Under normal conditions of temperature and pressure, PP-R pipes can be used for over 50 years.
4. Little resistance for water flow
The inner walls of PP-R pipes are smooth and limescale will notbe formed there. The wear resistance factor is only 0.007, considerabally lowerthan the matel pipes. The ability for carrying water for PP-R pipes increases byover 30% than the metal pipes with the same size.
5. Environmental
During the process of production, construction anduse, PP-Rpipes will not make any pollution to the environment.
6. Economical
The price for PP-R pipes is almost the same with the galvanizedpipes. With convenient construction, they are more cheap.
7. Light weight
The density of PP-R pipes is 0.89-0.9g/cm, only 1/8 of thesteel pipes, 1/10 of copper pipes. The light weight will reduce thetransportation cost and the construction intensity.
8. Healthy
The materials of PP-R pipes are formed with just two elements,that is, Carbon and Hydrogen. The sanitation performance of the materials haspassed the examination by the government authority.
9. Well corrosion-resistance
Except for few oxidents, the pipes can endure the erosion ofmany kinds of chemical materials. The pipes will not be rusted, get eroded,breed the growth of bacteria.
10. Little expansion force
The flexible moludus of PP-R materials is small. So theexpansion force formed with the change of temperature is little. They are suitedfor the installation of inside walls and concealed foor construction.
11. Complete accessories
PP-R pipe system have a full set of accessories and can meetthe requirements of general project.
12. Solid connection
PP-R pipe system adopts the hot-welding way for connection. Thepipes and fittings are linked together The tensile, bending and impact intensityat the interface is bigger than the pipe intensity, avoiding the hidden dangerof water leakage.
