Description

• PE100 Grade Material Integrity The use of high-density polyethylene (PE100) provides high chemical stability and resistance to environmental stress cracking. In underground drainage applications, this material prevents degradation from acidic or alkaline soil conditions and corrosive industrial waste, ensuring a consistent service life exceeding 50 years without the structural decay common in concrete or metal alternatives.
• Hollow Corrugated Profile Structure The external wall features a hollow corrugated rib design that provides high ring stiffness (SN4 to SN16) with minimal material weight. This structural configuration enables the pipe to withstand vertical soil loads and external pressure from heavy vehicle traffic, maintaining cross-sectional stability in deep-burial infrastructure projects.
• Optimized Hydraulic Flow Efficiency The smooth internal surface minimizes the Manning’s roughness coefficient (n ≈ 0.009), which reduces fluid friction and prevents the accumulation of silt and debris. For project engineers, this allows for higher flow velocities or the potential to use smaller pipe diameters at lower gradients, significantly reducing total excavation and material costs.
• Dual-Wall Co-Extrusion Bonding Manufactured using advanced German processing technology, the inner and outer layers are co-extruded and fused into a single unit, eliminating the risk of delamination. This thermal bonding ensures that the pipe maintains its flexible structural properties under seismic activity or ground settlement, preventing joint failure and groundwater infiltration.
• Lightweight Low-Inertia Design With a significantly lower density than traditional materials, these pipes can be handled and positioned without heavy-duty lifting machinery for smaller diameters. This reduces on-site labor requirements and logistics costs, particularly in remote agricultural irrigation or mine drainage projects where site accessibility is limited.
• Thermal and Environmental Adaptability The HDPE material properties remain stable across a wide temperature range, preventing brittleness in alpine regions and maintaining stiffness in tropical climates. This thermal resilience ensures consistent performance in diverse geographical markets, from Southeast Asian storm drainage to high-altitude infrastructure in Central Asia.
• Secure Bell and Spigot Jointing The standardized engagement lengths (Amin 54mm–118mm) and precision-engineered sockets allow for rapid, leak-proof connections using elastomeric sealing rings. This simplified jointing system ensures hydraulic sealing integrity under low-pressure conditions, protecting the surrounding soil environment from contamination.
• Non-Toxic and Chemically Inert Composition As a non-polar thermoplastic, the pipe is resistant to biological growth and does not leach harmful substances into the transported fluid. This makes the system suitable for environmentally sensitive subsurface drainage and the safe conveyance of agricultural water supplies without risk of soil or water table pollution.

Scope of application

• Municipal Sewage and Wastewater Collection This system is primary utilized for underground sewer pipe networks in urban infrastructure. It facilitates the conveyance of domestic wastewater and industrial effluents containing weak acids or alkalis (pH 2–12) at ambient temperatures. The smooth internal bore prevents solid deposition and biological scaling, ensuring consistent flow capacity in long-term municipal service.
• Stormwater Management and Flood Control In highway culvert installations and residential storm drainage systems, these pipes efficiently channel high volumes of rainwater to prevent localized flooding. The corrugated exterior profile allows the pipe to dissipate external soil stress and traffic loads, making it an ideal culvert pipe for installation under embankments, roadways, and airport aprons.
• Agricultural Irrigation and Farmland Drainage Engineered for low-pressure water supply and subsurface drainage, these pipes control water table levels in large-scale agricultural projects. They are used to transport irrigation water or drain excess groundwater containing fertilizers and soil minerals, where the lightweight nature of the PE material allows for rapid deployment across expansive rural terrains.
• Industrial Fluid and Mine Tailings Transport The chemical resistance of PE100 material enables these pipes to serve as reliable conduits for gravity-fed industrial fluids and mine drainage. They are specifically applied in mining operations to transport corrosive water or treated tailings, where the pipe's impact resistance ensures durability against the abrasive nature of suspended solids.
• Railway and Expressway Sub-base Drainage These pipes are integrated into the subsurface drainage systems of railway tracks and expressways to remove infiltrated water from the roadbed. By maintaining a dry sub-base, the pipes prevent frost heaving and soil softening, thereby preserving the structural stability of the transport infrastructure under continuous heavy-duty vibration.
• Underground Cable Protection and Ducting Beyond fluid transport, the high-density polyethylene structure provides a secure sheath for high-voltage power lines and telecommunications cables. Acting as a protective conduit, it shields internal cables from mechanical damage, soil moisture, and chemical erosion, facilitating safe cable routing under highways and within industrial complexes.
