Product Description

HDPE Structured Wall Pipe Engineered For Building Stormwater Networks Municipal Drainage And Sports Fields Civic Plazas Drainage

Product Profile

Polyethylene (PE) Spiral Structured Wall Pipe (Type A), also known as Hollow Wall Spiral Winding Pipe, is a structured-wall piping system manufactured from high-density polyethylene (HDPE) using an advanced hot-state spiral winding process.

This pipeline system is designed for gravity-flow fluid transmission at media temperatures below 45°C. It is widely specified for municipal drainage, building stormwater networks, buried agricultural irrigation and drainage, industrial effluent disposal, highway and road drainage, sewage treatment plant piping, sports fields and civic plazas drainage, as well as electrical and telecommunications ducting engineering.

Advantages

Feature	Performance & Benefit
Large Diameter Capacity	Capable of reaching massive dimensions, typically ranging from DN300mm to over DN3000mm, which standard DWC pipes cannot achieve.
Superior Ring Stiffness	Easily achieves high stiffness classes such as SN4, SN8, or higher, making it ideal for deep burial and high overburden pressure applications.
Excellent Axial Flexibility	As a flexible conduit, it deflects elastically to redistribute soil loads, offering excellent resistance to uneven ground settlement and seismic activity without cracking.
High Hydraulic Efficiency	The ultra-smooth inner wall (n ≈ 0.009) ensures maximum flow capacity, reduces pumping costs, and prevents slime or scale buildup.
100% Corrosion Resistant	Completely inert to acids, alkalis, salts, and domestic or industrial chemical wastewater, with a verified service life of 50-70 years.

Product Features

Reliable Ring Stiffness: Compared with pure plastic conduits, the steel-reinforced pipe design delivers a significantly more reliable and robust ring stiffness.
Smooth Interior & Low Friction: The ultra-smooth inner wall boasts a minimal friction coefficient, maximizing hydraulic flow efficiency and effectively preventing sludge accumulation or scaling.
Flexible, Leak-Free Jointing: The system supports flexible and leak-free connection methods—such as electrofusion tape welding and butt fusion—ensuring superior environmental sealing and preventing groundwater contamination.
Corrosion Resistance & 50+ Year Lifespan: Constructed from chemically inert HDPE, the pipe is highly resistant to chemical and environmental corrosion, guaranteeing a dependable service life exceeding 50 years.
Lightweight with Fewer Joints: Its lightweight structure eliminates the need for heavy lifting cranes during handling. The longer pipe sections reduce the number of joints, streamlining field installation.
On-Site Production Capabilities: The mobile pipe winding equipment is remarkably simple and compact. It can be transported directly to or near the project site for localized fabrication, drastically slashing logistical and freight costs for clients.
Superior Resistance to Abnormal Sudden Loads: Benefiting from excellent structural elasticity, the pipe safely dissipates unexpected external or sudden stresses through flexible deformation, preventing catastrophic failure or joint leaks.

HDPE Hollow Wall Spiral Winding Pipe is the ultimate heavy-duty solution when your project demands large diameters (over 1 meter), deeper burial depths, and absolute structural integrity.
