   Advantages:

1.Corrosion resistance, impregnable for corrosion soil and various kinds of water for life, high performance to inorganic acid, alkali, salt in corrosion resistance, suitable for excellent industrial sewage discharge and transportation.

2.Ageing resistance and long service life, and the normal service life is about 30-50 years. It is the building drainage, sewage ideal materials.

3.Shock resistance is strong, high mechanical strength.

4.Not easy to clog, no fouling, smooth inside, small fluid resistance, roughness coefficient is 0.009, unhindered stream, little maintenance.

5. Not out of the rust water, ensuring external do not rust, resist the oxygen index is high, with self-extinguishment.

6. Light weight, for iron 1/10, handling and installation are convenient, comparing to cast iron pipe improve efficacy 40-60%, obviously reduce project cost.

7. Pipeline swell factor is small, thermal conductivity and elastic modulus is small, and it has excellent drain freezing resistance performance compared with iron pipe.

8.Using unique auxiliary, avoid termites, pet biting damage.

9.Great variety of goods, can cooperate with various design and installaion standarsd.
