PPR Fittings Type II
PPR is a type of polypropylene plastic pipe that has some advantages over other plastic pipe used in residential and commercial plumbing. The main advantages are stability, durability and leak resistance.
1 | High temperature resistance-Vicat softening point is 30-40℃ higher than that of PVC and can be used in cold and hot water systems. |
2 | Compressive strength-the wall thickness of the pipe under the same pressure can be thinner than that of PVC. |
3 | Corrosion resistance-enhances the corrosion of fluids such as acids, alkalis, salts, oxidants, etc., and can be used in industries such as steel, metallurgy, petroleum, chemical, fertilizer, dyes, pharmaceuticals, electric power, environmental protection, and sewage treatment |
4 | Good heat insulation performance-has extremely low thermal conductivity, therefore, the pipe made of CPVC has light weight, good heat insulation performance, and does not need heat preservation |
5 | High flame retardant-can be used in fire piping system |
