HDPE DWC Pipe Project | Shaanxi Shifajie Industrial

Project Overview

Our HDPE DWC Pipe project sets a new benchmark for municipal drainage solutions.We completed this HDPE DWC pipe project for a municipal client in 2025.
We installed 10,000 meters of high-performance HDPE double wall corrugated pipes.
For exampie ,the project upgraded the city’s drainage system and prevents flooding during heavy rain.
It has been running stably for 8 months and won high praise from the local government.

Product Core Advantages

Excellent Corrosion Resistance

Our HDPE DWC pipes are made of premium virgin polyethylene materials.
They resist chemical erosion from sewage, acid and alkali substances.
This feature extends the service life of the pipes in harsh environments.

50+ Years Service Life

The pipes adopt a double-wall corrugated structure for enhanced pressure resistance.
They can withstand long-term underground pressure and soil deformation.
Our products have a service life of over 50 years, reducing maintenance costs.

Environmentally Friendly & Recyclable

All our HDPE DWC pipes are non-toxic and pollution-free.
in addition,they can be fully recycled after the end of their service life.
This meets the international environmental protection standards for infrastructure projects.

Construction Process Highlights

1. We conducted on-site geological surveys before construction.

2. We customized the pipe diameter and length according to project needs.

3. Also,our professional team completed the installation in 45 days with zero errors.

4. We carried out strict pressure tests to ensure no leakage after installation.
