1. Unique structure, high strength, compression and impact resistance.
2. The inner wall is smooth, frictional, and the over-flow is large.
3. Convenient connection, well sealed joint, no leakage.
4. Light weight, fast construction and reduced costs.
5. The service life of buried ground is more than 50 years.
6, polyethylene is a hydrocarbon polymer, the molecule is non-polar, resistant to acid and alkali corrosion.
7. The raw materials are environmentally friendly materials, non-toxic, non-corrosive, non-scaling, and can be recycled and reused.
8. The applicable temperature range is wide, the pipeline does not break in the environment of -60 ℃, and the maximum temperature of the conveying medium is 60 ℃.
9. The comprehensive engineering cost is basically the same as that of concrete, and the operating cost is low.
10. No foundation is required if the soil is good.
