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

2. Good hydraulic characteristics: This characteristic is particularly prominent in the field of water supply and drainage, with good hydraulic characteristics.

3. 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.

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

5. Non toxic, can be used to transport drinking water. thirty-four
