- Commodity name: PP-R pipe for hot and cold water
We use high-quality materials to solve your building water supply problems. PP-R hot and cold water polypropylene pipes are made of high-quality PP-R raw materials such as North European Chemical RA130E-8427, Korea Oil RP2400 or Yanshan Petrochemical C4220, as well as PP-RCT raw materials from Nordic Chemical, according to your requirements for raw materials, while meeting the scale of project use. Production is carried out with extrusion and servo injection molding lines.

1. For high-rise and super high-rise buildings with working pressure higher than 0.6MPa, PP-RCT pipes within the allowable working pressure range should be selected.
2. High-rise and super high-rise buildings in low areas or multi-storey buildings (not more than seven floors), the working pressure is not greater than 0.6MPa, it is appropriate to choose the corresponding allowable working pressure range of PP-R pipe.
3. When dn25mm and the following specifications need to be embedded in the wall or buried and other dark coating construction, you can choose PE-RTII pipe with excellent flexibility and not easy to "rebound" to form stress concentration within the corresponding allowable working pressure range.
4. In cold weather construction, PE-RTII pipe or PE100 pipe can be selected within the corresponding allowable working pressure range -
◆ Good heat resistance
Under the standard design pressure, the long-term use temperature of PP-R tube can reach 70°C, and the service life can reach more than 50 years.
◆ Safe connection of pipeline system
Mainly using hot melt or electric melt, the tensile, bending and impact strength of the interface are higher than the pipe body.
◆ Environmental protection, non-toxic
PP-R is a polyolefin material, health, non-toxic, no rust, no pollution to the water quality, in the construction and use of the process of no pollution to the environment, is a healthy environmental protection type of green building materials, health performance in full compliance with GB/T 17219-1998 provisions.
◆ Good corrosion resistance
In addition to the water number of strong oxidant and copper, it can resist the erosion of a variety of chemical media.
◆ Low water resistance
The pipe wall is smooth without fouling, and the pipe fittings with special structure design ensure that the effective diameter of the socket welding is large and the flow is not reduced. Its friction coefficient is only about 0.007, much lower than the metal pipe, water capacity than the same specifications of the metal pipe increased by about 30%.
◆ Small expansion force
Because the amount of elastic film is small, the expansion force generated by temperature change is small, and it is suitable for the construction of direct embedding in the wall and the floor layer. Light weight, convenient handling, greatly reducing the handling, transportation costs and installation of the construction intensity.
