uv protection pex pipe .
uv protection pex pipe advantages
1.Domestic innovative pex composite pipe has double layers,white lining,has passed the drinking water hygiene standards.The outer layer containing carbon black anti-ultraviolet radiation. The service life is 25 yr if pipes being exposed to the outdoor and 50yr used inside.This pipe filled the blank of outdoor UV resistant and heat-resistant pipe.
2.Advanced formulation technology and reactive extrusion process ensures the high quality of the production process as well as the products.
3.Supporting tube technology: advanced expanding-type pipe fitting ensures the reliability of technical connected.
