DWC Pipe (Double Wall Corrugated)

The Strongest & Most Efficient Underground Piping Solution

Double Wall Corrugated (DWC) pipes have become the backbone of underground drainage, sewage, and cable protection systems across India. At Genix Polymers Pvt. Ltd., we manufacture SN-8 grade DWC pipes designed for maximum strength, durability, and long-term reliability. We offer DWC pipes in 150 mm, 200 mm, 250 mm, and 300 mm, suitable for heavy-duty municipal and industrial applications.

1. Unique Dual-Layer Design for Maximum Strength

DWC pipes have a corrugated outer layer that provides structural strength and a smooth inner surface ensuring high flow efficiency. This double-layer design allows the pipe to withstand: 

• Heavy soil loads

 • Traffic pressure Harsh environmental conditions 

• Ground movement

2. SN-8 Stiffness Rating – Built for Heavy Loads

Genix DWC pipes are manufactured with an SN-8 stiffness class, ensuring exceptional load-bearing capability. This rating makes them suitable for:

  •  High-traffic roads 
  • Industrial zones 
  • Municipal drainage 
  • Railway and highway installations 

SN-8 ensures long-term reliability even under extreme pressure.

3. Ideal for Underground Drainage and Sewage

DWC pipes offer outstanding flow characteristics and are widely used for: 

  • Underground drainage lines 
  • Stormwater management 
  • Sewage networks
  • Municipal water outflow systems 

Their smooth inner surface prevents clogging and reduces maintenance.

4. Best for Cable & Utility Ducting

DWC pipes provide excellent mechanical protection for: 

  • Electrical cables 
  • Optical fiber cables 
  • Telecom networks 
  • Utility ducting systems 

Their high impact resistance ensures cable safety during installation and operation.

5. Lightweight & Easy to Install

Compared to RCC or metal pipes, DWC pipes are much lighter, enabling: 

  • Faster installation 
  • Reduced labor effort 
  • Lower transportation cost 
  • Easier handling at project sites

      6. Resistant to Corrosion & Chemicals

      Made from high-grade HDPE, DWC pipes are resistant to: 

      • Corrosive soils 
      • Industrial waste chemicals 
      • Moisture exposure 
      • Abrasion and sediment buildup

       This ensures long service life and trouble-free operation.

      7. Strict Quality Testing at Every Stage

      Every DWC pipe manufactured at Genix undergoes: 

      • Stiffness testing 
      • Impact resistance testing 
      • Dimensional accuracy checks 

      • Leakage and load-bearing tests 

      Quality consistency is ensured through advanced equipment and expert supervision.

      8. Conclusion

      Genix DWC pipes deliver superior reliability, strength, and cost-efficiency, making them the top choice for underground drainage, sewage, and cable protection projects. Designed for heavy-duty environments, our SN-8 pipes guarantee long-lasting performance, safe installations, and smooth flow ideal for modern infrastructure and municipal development.
