1. Three layer structure: inner layer of thermoplastic polyethylene, middle layer of high-strength steel wire skeleton, outer layer of thermoplastic polyethylene.
2.The three layers are completely integrated together with a special adhesive resin. The steel wire is spiraled and formed a mesh skeleton of the reinforced polyethylene pipe.
3.The inner wall is smooth and the flow resistance is small, no scaling. It is sanitary & non-toxic, has good flexibility, high pressure resistance, chemical corrosion resistance.
4.Good impact resistance and stress cracking resistance at low temperature, light weight, easy to install, and life period is up to 50 years.
