1. Reliable sanitation performance.

2. Good impact strength under low temperature.

3. Good resistance to crack under stress.

4. Good anti-friction performance, high corrosion and aging resistance, with long lifetime.

5.  Good flexibility.

6.  Small flowing resistance.

7.  Easy for carrying and loading, and fixed joint.

8.  New construction method: Besides traditional digging method, other new un-digging methods like pushing-out,oriented drilling and lining are also available, which is the solo choice for the no digging-permission conditions, so PE pipes for water supply are applied more widely.
