Product Profile

Polyethylene (PE) Spiral Structured Wall Pipe (Type A), also marketed as Hollow Wall Spiral Winding Pipe, is a high-performance structured-wall conduit system manufactured from high-density polyethylene (HDPE) through a precision hot-state spiral winding process. Purpose-designed for underground utility infrastructure, it provides reliable, long-life protective ducting for high-voltage power cables, fiber optic telecommunications networks, and critical utility corridor installations.

This conduit system is designed for permanent underground installation at ambient ground temperatures below 45°C. It is extensively deployed in urban utility tunnel cable duct banks, high-voltage transmission cable protection, telecommunications fiber optic trunk routes, airport and seaport lighting cable conduits, railway signaling and communications ducting, renewable energy farm cable networks, and smart city infrastructure corridor installations.

Utility Ducting Advantages
Feature Performance & Benefit
Multi-Cable Large Diameter Capacity Capable of producing internal diameters from DN300mm to over DN3000mm, accommodating multiple high-voltage cable bundles, fiber optic trunk lines, and utility service pipes within a single protective conduit structure.
High Ring Stiffness for Utility Corridors Easily achieves SN4, SN8, or higher stiffness ratings, providing robust protection for sensitive cables and fiber optics under urban roadway traffic loading, deep utility corridor burial, and construction activity above.
Excellent Ground Movement Compliance As a flexible conduit, it accommodates differential ground settlement, seismic displacement, and thermal expansion of adjacent structures without the cracking and cable exposure risks of rigid concrete duct banks.
Superior Cable Pulling Efficiency The ultra-smooth interior surface (n ≈ 0.009) dramatically reduces cable pulling tension, enabling longer continuous cable pulls, reducing the number of pulling pits, and protecting cable sheaths from installation abrasion damage.
Permanent Underground Corrosion Immunity Completely inert to groundwater chemistry, soil acids, stray electrical currents, and electrolytic corrosion. Provides a verified 50-70 year protective service life for critical power and telecom cable infrastructure.
Ducting Product Features
  • Cable Protection Ring Stiffness: The hollow-wall structural design provides substantially higher ring stiffness than standard cable conduit, ensuring permanent cable protection under heavy traffic, deep burial, and post-installation construction activity in urban utility corridors.
  • Low-Friction Cable Installation: The mirror-smooth interior bore significantly reduces cable pulling friction coefficients, enabling ultra-long cable pulls that minimize the number of access chambers, pulling pits, and joint bays in urban infrastructure projects.
  • Watertight Environmental Sealing: Electrofusion tape welding and butt fusion jointing produce fully sealed connections that prevent groundwater ingress into cable ducts and eliminate the risk of cable insulation degradation from prolonged water immersion.
  • 50+ Year Infrastructure Protection: Constructed from chemically inert HDPE with complete resistance to soil chemistry, groundwater, and stray current corrosion. Guarantees continuous cable protection for over 50 years matching the operational life of power and telecom assets.
  • Lightweight Handling in Urban Sites: The lightweight structure simplifies transportation and handling in congested urban utility corridor construction sites, reducing crane requirements, traffic disruption, and construction duration compared with concrete duct banks.
  • On-Site Manufacturing Capability: The compact spiral winding equipment can be positioned at project staging areas for localized production, eliminating long-distance transportation costs for large-diameter duct and enabling responsive supply to fast-track utility projects.
  • Exceptional Resilience to Abnormal Loads: The structural flexibility safely absorbs and dissipates unexpected loads from construction activity, ground settlement, and seismic events through elastic deformation, maintaining continuous cable protection without structural failure.
HDPE Hollow Wall Spiral Winding Pipe is the definitive underground utility protection solution when your power or telecom infrastructure demands large-diameter multi-cable duct banks (over 1 meter), deep urban burial ratings, and 50+ years of uninterrupted cable protection in critical infrastructure corridors.
