In municipal engineering, what are the core advantages of HDPE double-wall corrugated pipes compared to concrete pipes?

Question

Accepted Answer

In municipal drainage projects, HDPE double-wall corrugated pipes offer revolutionary advantages.

First, they are only 1/10th the weight of concrete pipes, eliminating the need for large lifting equipment and increasing construction efficiency by over 50%.

Second, the use of electrofusion socket or butt fusion joints achieves zero leakage, preventing groundwater contamination.
Third, the unique corrugated structure provides high ring stiffness (up to SN16), effectively withstanding backfill loads and traffic pressure.

Fourth, the smooth inner wall has a low friction coefficient, offering a flow capacity up to 30% higher than concrete pipes of the same diameter.

Fifth, they are resistant to acid and alkali corrosion, with a service life exceeding 50 years, resulting in lower lifecycle costs.

Jianlong's HDPE drainage pipes have passed SGS testing, and we provide complete engineering design solutions, making them an ideal upgrade replacement for traditional concrete pipes.
