1. Long service life: normal service life can reach more than 50 years;

2. Excellent corrosion resistance: except for very few strong oxidants, it can resist the erosion of various chemical media and has good leakage resistance;

3. Excellent wear resistance: compared with the wear resistance of steel pipes, the wear resistance is more than 4 times that of steel pipes;

4. Good low temperature resistance and impact resistance: good toughness, high impact resistance; low brittle temperature, use range of minus 60 degrees to 40 degrees Celsius;

5. Good construction performance: the pipeline is light and easy to construct, the connection is reliable, and the comprehensive cost of the project is low;

6. Good flexibility: the pipeline is flexible, can be bent moderately, and has good anti-uneven settlement effect;

7. Low water flow resistance: the inner surface of the pipe is smooth, the fluid resistance is small, and the pressure loss and water transmission energy consumption of the pipeline can be reduced.
