   PE water supply pipe has the following characteristics:

  1. PE water supply pipe has corrosion resistance, good sanitary performance and long service life.

  2. PE water supply pipe has good flexibility and excellent scratch resistance.

  3. PE water supply pipe can withstand low temperature.

   4. PE water supply pipe has good rapid crack growth fracture toughness.

   PE water supply pipe material is polymerized from monomer ethylene. Due to different polymerization conditions such as pressure and temperature, resins with different densities can be obtained during polymerization. Therefore, it can be divided into high-density polyethylene, medium density polyethylene and low-density polyethylene.
