Description

• Hot-Wound Structural Integrity The HDPE and PP profiles are fused in a molten state to eliminate internal stress. This prevents wall delamination under long-term soil pressure, ensuring a 50-100 year service life and significantly reducing system rehabilitation costs.
• Integrated Electro-fusion Jointing Built-in heating elements in the socket create a molecular-level bond during welding. This forms a homogeneous, 100% leak-proof connection that eliminates groundwater infiltration and environmental contamination risks for the entire piping system.
• High Ring Stiffness (SN8-SN16) The spiral-reinforced design provides exceptional radial load capacity (up to SN16) without excessive weight. It safely withstands deep burial and heavy traffic loads, ensuring long-term road stability for airports and highways.
• Optimized Hydraulic Flow Efficiency A smooth inner wall with a Manning’s coefficient of 0.009 minimizes fluid friction. This prevents silt accumulation and maintains high flow capacity, allowing engineers to specify smaller, more cost-effective pipe diameters for urban drainage.
• Superior Corrosion & Abrasion Resistance The PE100 material resists H₂S, acids, and abrasive particles found in industrial waste. It prevents wall thinning and premature failure, providing high durability in aggressive sewage, mining, and coastal soil environments.
• Flexible Seismic & Subsidence Adaptation High elongation at break allows the pipe to flex without brittle fracture or joint failure. This characteristic accommodates uneven ground subsidence and seismic activity, providing essential "safety insurance" for infrastructure in soft soil zones.
• Logistical & Installation Economy The lightweight structure supports "nested loading" to maximize container space and reduces the need for heavy on-site cranes. This dramatically lowers shipping costs and shortens installation timelines for large-scale international projects.

Scope of application

• Municipal Sewage and Stormwater Systems As a primary collector for urban wastewater, this HDPE winding structure wall reinforced pipe handles domestic sewage and storm runoff. Its SN8-SN16 ring stiffness and zero-leakage electro-fusion joints prevent groundwater infiltration and road subsidence, ensuring long-term structural safety in high-density urban infrastructure.
• Industrial Effluent and Waste Management This system is deployed in chemical and pharmaceutical plants for discharging corrosive wastewater. The PE100 material resists a wide pH range of acids and alkalis. Its inert chemical properties ensure secure conveyance between processing units and treatment plants without the risk of pipe wall degradation.
• Heavy-Duty Infrastructure Drainage Engineers specify this pipe for drainage beneath airport runways, railway embankments, and highway culverts. These environments subject the pipe to intense dynamic loads. The flexible structural wall design effectively distributes external stresses, maintaining the stability of the transport infrastructure above without brittle fracture or joint failure.
• Mining Tailings and Mine Water Transport Used for gravity-fed transport of abrasive tailings and acidic mine water, this pipe leverages its high abrasion resistance. It effectively manages internal wear from suspended solids while maintaining structural performance in the harsh, corrosive geotechnical conditions typically found in international mining operations.
• Coastal Outfalls and Marine Intake Lines In marine engineering, the Krah Pipe is ideal for sea outfalls and saltwater intake. The material is inherently resistant to saltwater corrosion and biological growth. Its flexibility allows the pipeline to conform to natural seabed contours and accommodate tidal movements without compromising integrated electro-fusion connections.
• Landfill Leachate Collection Systems Required for collecting chemically complex fluids under extreme burial depths, this pipe ensures the drainage path remains open under massive waste loads. The smooth internal bore prevents chemical precipitate accumulation, while the reinforced structural wall provides the radial strength necessary for long-term landfill leachate management.
• Agricultural Irrigation and Land Drainage Large-scale projects utilize this pipe for long-distance water transportation and saline-alkali land drainage. Its low Manning’s coefficient (n=0.009) ensures high flow efficiency. Resistance to soil salinity and easy installation make it a cost-effective solution for improving soil quality and water distribution in rural regions.
