PPR din valve

ppr din valve(AS):

Application:

1. Cold and hot water systems  of  residence and  commercial  buildings.

2. Transportation of industrial water supply  and chemical  materials.

3. Pure water pipe system.

4. Piping networks for rainwater utilization  systems.

5. Irrigation systems  for gardens.

6. Transportation system  of  drinking  water production.

7. Piping networks for solar plants.

8. Other pipes in industry and agriculture.

Features:

1. Well heat resistance ability

   The pipes can be used for a long time while the working temperature of  water is 70°C. They can be used for a short time while it reaches 95°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 not be formed there. The  wear resistance factor is only 0.007, considerabally lower than the matel pipes. The ability for carrying water for PP-R pipes increases by over 30% than the metal pipes with the same size.

5. Environmental

   During the process of production, construction and use, PP-R pipes will not make any pollution to the environment.

6. Economical

   The price for PP-R pipes is almost the same with the galvanized pipes. 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 the steel pipes, 1/10 of copper pipes. The light weight will reduce the transportation 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 has passed the examination by the government  authority.

9. Well corrosion-resistance

   Except for few oxidents, the  pipes can endure the erosion of many 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 the expansion force formed with the change of temperature is little. They are suited for the installation of inside walls and concealed foor construction.

11. Complete accessories

   PP-R pipe system have a full set of accessories and can meet the requirements of general project.

12. 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.
