Faithful hdpe double-wall corrugated pipe shall be strictly implemented CECS 223:2007, technical specification for embedded polyethylene pipe drainage pipe engineering CECS164:2004, GB 50268-97 code for construction and acceptance of water supply and drainage pipe engineering
1. Unique structure, high external compressive strength, impact resistance, flexible ring, small frictional resistance on the inner wall and large flow of pipes with the same internal diameter; Socket interface, flexible connection, convenient connection, high reliability, not easy to leak.
2. Light weight, quick construction and low cost.
3. The service life of buried ground reaches over 50 years.
4. Polyethylene is a hydrocarbon polymer with non-polar molecules and is resistant to acid and alkali corrosion.
5. The raw materials are green and environment-friendly, non-toxic, non-corroding and non-tarnish, which can be recycled and reused.
6, suitable temperature range wide, pipeline rupture, 60 ℃ environment medium maximum temperature of 60 ℃.
7. The cost of comprehensive engineering is basically the same as that of concrete, and the operating cost is low.
8. No foundation is needed if the soil is of good quality
