1.Excellent corrosion resistance 2.Excellent abrasion resistance, 3.Easy operation 4.Recyclable, 5.Good impact resistanc

HDPE corrugated pipe with double wallsProduct advantages:

1. High density, good compression resistance and good impact resistance;

2. Good resistance of asymmetrical bedding, available being buried in the mollisol and quicksand;

3. Rubber ring connection, easy but no leakage in the joit;

4. Smooth interior wall and low friction, high flow capacity;

5. Good corrosion resistance and no environment pollution;

6. Light weight, easily transport and install, low construction cost;

7. Application: municipal sewage; rainwater discharge; floodwaters drainage; irrigation; ventilation for mine and buildings; industrial waste discharge.
