1.      High corrosion and aging resistance, so over 50 years of long lifetime.

2.      High impact strength and mechanical strengh, with high inner pressure and tension strength.

3.      No jam-up and sediment, smooth internal wall, so samll friction and little damage to the water power.

4.      No smell and poison, mo rust, so without re-pollution to the water and pureness.

5.      1/5 Lighter than cast iron pipes, easy for carrying, loading & unloading and installation, so 40-60% more efficient than cast iron pipes with low cost of construction.

6.      Good sealing performance.

7.      Special additives which make products free from stange smell mice and bugs like, so avoiding been bitten by them.
