DWC Pipes

Double Wall Corrugated (DWC) Pipes
for Drainage & Ducting Systems

Edoburg’s DWC (Double Wall Corrugated) pipes are built to meet the demanding requirements of underground drainage, non-pressure sewerage, and telecommunication cable protection. With a smooth inner bore and high-rigidity corrugated outer shell, DWC pipes offer superior mechanical strength while maintaining excellent hydraulic efficiency.

 

Manufactured from high-grade polyethylene (HDPE/PP), Edoburg DWC pipes are supplied in coil and cut lengths and conform to international dimensional and performance standards. These pipes are suitable for global applications in infrastructure, utility management, telecom, and highway construction.

Standards

International Specifications

Edoburg DWC pipes are produced under strict quality control to conform to international specifications for utility infrastructure:

  • IS 16098 (Part 2) – Structured wall pipes for non-pressure drainage and sewerage applications

  • EN 13476 – European specification for structured-wall piping systems made of thermoplastics

  • ISO 21138 – International standard for buried piping systems for non-pressure drainage

 

Available in:

  • Sizes: DN 100 mm to DN 1000 mm (ID/OD-based)

  • Lengths: Standard 6m lengths, or coiled options for telecom ducts

  • Load Class: SN 4, SN 8, SN 10 (based on site loading)

 

Each batch is tested for stiffness, impact resistance, elongation, and dimensional accuracy.

Types of DWC Pipes Edoburg offers

Engineered for Longevity, Load

Resistance & Installation Efficiency

DWC pipes are widely adopted in infrastructure and urban development projects due to their strength, versatility, and ease of deployment.

​

  • Dual-wall design: smooth inner wall ensures low flow resistance, outer corrugated wall ensures high strength

  • High ring stiffness and crush resistance under soil load

  • Lightweight for quick handling, trench laying, and jointing

  • UV-resistant and chemically inert for long-term buried use

  • Suitable for both gravity drainage and protective ducting

  • Minimal silt accumulation due to smooth bore

Reliable for Drainage, Sewerage

& Protective Ducting Systems

Edoburg’s DWC pipes are recommended for the following global use cases:

​

  • Underground Drainage Systems – Non-pressure drainage for municipal and urban projects

  • Stormwater & Rainwater Management – In residential layouts, commercial estates, and road shoulders

  • Cable Protection – Telecom and power cable conduits in highways, airports, industrial parks

  • Sewerage Networks – Gravity-fed non-pressure pipelines in residential and commercial zones

  • Industrial Effluent Channels – Low-pressure discharge piping in factories and processing zones
