Double Wall Corrugated (DWC) HDPE Pipes engineered to deliver superior strength, durability, and hydraulic performance for underground infrastructure applications. Featuring a corrugated outer wall for enhanced ring stiffness and a smooth inner surface for reduced friction losses, these pipes ensure efficient flow characteristics and facilitate easy cable installation. Manufactured from high-density polyethylene, DWC pipes offer excellent resistance to corrosion, chemicals, abrasion, and biological attack, making them a dependable alternative to conventional RCC, GI, and PVC piping systems.
Designed for long-term service and ease of installation, our double wall corrugated HDPE pipes are widely used for electrical and telecom cable ducting, stormwater drainage, sewerage networks, and utility infrastructure projects. Their lightweight construction, flexibility, and leak-tight jointing systems help reduce transportation, handling, and installation costs while ensuring reliable performance under varying soil and loading conditions. Available in a range of diameters and configurations, these pipes provide a cost-effective and sustainable solution for modern civil and utility engineering applications.
The twin-layer conduit is available from diameter 40 mm to diameter 200 mm in coils and bars.
Our HDPE Pipes are compliant with the following standards:- CEI EN 61386-1
- CEI EN 61386-24
- European LV Directive 2014/35/EU
Characteristics of HDPE Duct Pipes
- Thanks to its flexibility the pipe can be installed in any ground and slope. The flexibility helps to avoid all kind of obstacles with no need for bends.
- Elasticity helps to absorb all stresses caused by the ground settlements. It can be installed in any ground, in underground shafts, as well as in moist, wet and aggressive environments.
- Its lightness makes storing, transport and installation very easy.
- Cables available in different colors for easier identification. Multiple die saddles for the construction of multi-pipe systems.
- It is supplied in 50 m coils (25 meters for DN 200 mm), all provided with 1 coupler.
Applications
Our Duct Pipes are used for the passage and underground protection of LV electrical cables, telephone wires and telecommunication systems.
