PE给水.jpg












Pressure grade:0.4MPa1.6MPa

Specification:dn20mmdn1200mm

Standard: GB/T13663.2-2018GB/T13663.2-2018 PE Pipes for Water Supply.

Performance features:

Low density, light weight, easy to handle and install;

Corrosion resistance to various chemical medium;

Excellent hydraulic performance: the wear resistance coefficient is only 0.009;

Long service life: up to 50 years;

Reliable connection;




PE is a kind of inert material. It can resist the corrosion of various chemical medium and microorganisms except for a few strong oxidants. The corrosion resistance of HDPE materials to common chemical medium under different temperature and medium concentration is shown in the table below :




Note: Please contact the technical department of our company if consulting the anti-corrosion performance of the pipes against other chemical medium.
