Double Wall Corrugated Pipe (DWC Pipe)
RDSO / Spec No.
N/A (Standard Commercial / Industrial Specification)
Application
Indian Railways (S&T / Electrical Sector) - Underground Cable Protection & Signal Ducting
Product Specifications & Details
Double Wall Corrugated (DWC) HDPE Pipes are engineered to provide maximum strength, flexibility, and protection for underground cable installations. Featuring a corrugated outer surface for superior load-bearing capacity and a smooth inner wall for effortless cable pulling, these high-density polyethylene pipes deliver robust defense against moisture, chemical corrosion, and mechanical stress. Ideal for railway signaling protection, telecom ducting, and low-tension electrical underground cable networks, DWC pipes ensure long service life and rapid site installation.
Key Advantages & Features
- Structural Integrity: Excellent impact and compression strength; retains circular cross-section even when bent.
- Watertight Protection: Moisture-proof and watertight sealing ensures complete environmental cable shielding.
- Durability & Inertness: Chemically inert, environmentally friendly, with exceptional weathering resistance.
- Railway Signaling Protection: Ideal for protecting underground LT power cables, S&T signaling lines, and tendon monitoring.
- Efficient Installation: Lightweight design with fewer required joints allows speedy installation and easy coupling.
- High Flexibility: Combines high ring stiffness with structural flexibility and strong concrete bonding capability.
