Our production line is capable of producing large plastic pipes ranging from 200mm to 3000mm in diameter. These HDPE spiral pipes are connected using specialized fittings (electric fusion sleeves, heat shrink sleeves), ensuring convenient and economical construction.

High Ring Stiffness: Ensures excellent resistance to external pressure and soil deformation.

High Impact Strength & Low Weight: Combines outstanding impact performance with lighter self-weight, simplifying transportation and installation.

Good Creep Deformation Resistance: Maintains shape under long-term pressure, guaranteeing stable and durable pipeline systems.

Excellent Outer Pressure Resistance: Capable of withstanding high external loads and soil pressure.

Strong Erosion Resistance: Offers superb resistance to various chemical media, including acids, alkalis, and salts.

Ultra-Long Service Life: Designed for an approximate 50-year lifespan, significantly reducing maintenance costs.

Given its superior performance, HDPE structured wall pipe is widely used in various critical areas:

Storm Water Management: Including storm water attenuation, runoff control, and drainage pipelines.

Sewerage Pipelines: For urban and industrial wastewater discharge systems.

Drainage Pipelines: For various drainage projects.

Culverts: Used for passages under roads and railways.

Pipe Rehabilitations: For relining existing aging pipelines.

Landfill Drainage/Leachate Collection: Ensuring environmental compliance.

Mine Drainage: Designed for complex mining environments.

HDPE Manholes/Manhole Drops: Providing complete solutions.

Floats: For applications in water engineering.

Irrigation: Agricultural and landscape irrigation systems.
