1. Long service life: Normal service life can be more than 50 years.

2. Excellent corrosion resistance performance: With excellent anti-leakage resistance, it can be resistant to the erosion of a variety of chemical media apart from very few strong oxidants.

3. Excellent wear resistance: Four times higher compared with steel pipes.

4. Satisfactory low temperature and impact resistance: With good toughness, high impact resistance intensity and low brittle temperature, the pipe can be used between -60℃ and -40℃.

5. Good workability: Light weight, convenient to use during construction, safety connecting, low integrated project costs.

6. High reliability: Because of its high flexibility and differential settlement resistance, the pipe can be bended reasonably.

7. Low water flow resistance: Smooth inner surface, low liquid flow resistance, pressure loss of the pipeline and energy consumption for water transmission can be reduced.
