1. Lightweight and high-strength: The specific gravity of sanitary grade pipelines is 1.65-2.0. For the weight per unit length of the same pipe diameter, it is only 1/3 of carbon steel, 1/5 of Cast iron pipe and 1/10 of prestressed concrete pipe, which reduces the hoisting cost and improves the installation speed during construction.

2. Good hydraulics characteristics: this characteristic is particularly prominent in the field of water supply and drainage, and its hydraulic characteristics are good.

3. Good water and corrosion resistance: Sanitary grade pipelines have excellent corrosion resistance, reducing anti-corrosion costs and extending service life; At the same time, due to its non rusting properties, the water quality of the transmission system is not subject to secondary pollution. It can also be used to transport media such as sewage, mud, seawater, etc.

4. Pressure resistance: Design and manufacture pipes and fittings according to the pressure required by the process, and conduct a water pressure test at 1.5 times the pressure required by the process.

5. The interface has good sealing performance, no leakage, no rupture, and increases the safety and reliability of water supply.

6. Non toxic, can be used to transport drinking water.
