HDPE DWC Pipe
HDPE DWC pipe, also known as double wall corrugated pipe, features a corrugated outer wall and a smooth inner wall. It is designed for non-pressure underground drainage, sewer, stormwater, agricultural drainage and cable protection projects requiring high ring stiffness, corrosion resistance and efficient flow performance.
- Diameter: DN110-1200mm.
- Ring Stiffness: SN4, SN8
- Material: High-Density Polyethylene
- Length: 6m.
- Structure: Corrugated outer wall and smooth inner wall
- Connection: Socket with rubber sealing ring
- Main Application: Underground drainage and sewer systems
- Delivery: 7-10 days depending on the total quantity.
Double Wall Corrugated Pipe Feature
- 1. DWC pipes are produced from the highest quality HDPE raw materials and have a long service life of 50 to 70 years.
- 2. The HDPE DWC pipe has a double-wall design, with a corrugated outer wall for high strength and a smooth inner wall for easy flow.
- 3. The DWC pipe has high ring stiffness and excellent ability to resist external loads and soil pressure.
- 4. Double wall corrugated pipes are resistant to corrosion, rust, scale, wear, and UV rays, and can adapt to various extreme environments.
- 5. HDPE corrugated pipes are usually connected with rubber gaskets or couplers to create a watertight seal and the joints are leak-proof and strong.
DWC Pipe Application
- 1. HDPE double wall corrugated pipes can be used in municipal drainage, urban drain piping system.
- 2. DWC sewer pipe can be used in apartments, residential district underground buried sewage drainage.
- 3. Double-wall corrugated pipe are suitable for highway embedded pipeline, golf course underground water seepage pipe network.
