  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.
