Description

• PE100 & PE100RC Stress Resistance Utilizing high-grade PE100 and PE100RC (Resistance to Crack) raw materials significantly increases the pipe's resistance to slow crack growth (SCG) and point loading. For the engineer, this allows for installation in challenging terrains or via trenchless technologies such as Horizontal Directional Drilling (HDD), effectively reducing project costs by minimizing the need for imported sand bedding and specialized backfill.
• Standardized Pressure Ratings (PN5 to PN25) Manufactured to ISO 4427, EN 12201, and AS/NZS 4130 standards, these pipes offer precise SDR ratings (SDR33 to SDR7.4) to match specific hydraulic requirements. This engineering precision ensures the pipeline can withstand calculated water hammer effects and internal pressure fluctuations, providing the procurement team with a high-safety-factor solution that prevents premature pipe bursting.
• Monolithic Leak-Proof Jointing The thermoplastic properties of PE100 enable butt fusion and electrofusion welding, creating a joint that is physically stronger than the pipe itself. In field operations, this eliminates the vulnerability of mechanical joints or gaskets, resulting in a zero-leakage system that significantly reduces Non-Revenue Water (NRW) losses and prevents local soil erosion at connection points.
• Hydraulic Efficiency via Smooth Bore The smooth internal wall of the HDPE water supply pipe results in a low friction coefficient (Hazen-Williams C factor of approximately 150) and prevents the accumulation of scale or biological growth. This sustained hydraulic capacity reduces the energy required for pumping over the 50-year design life, delivering a measurable reduction in the project's long-term operational expenditure (OPEX).
• Electrochemical Corrosion Immunity As a non-conductive polymer, HDPE is immune to galvanic and electrochemical corrosion, requiring no cathodic protection or external coatings. This material stability prevents the "tuberculation" and rust common in ductile iron or steel pipes, ensuring consistent water quality and eliminating the need for expensive chemical cleaning or premature pipe relining.
• UV Stabilization and Environmental Adaptability The inclusion of carbon black in the black-with-blue-stripes formulation provides resistance to ultraviolet degradation during outdoor storage and installation. This material stability allows the pipe to maintain its mechanical properties in high-temperature or high-UV regions like Southeast Asia and Africa, preventing premature embrittlement before the pipe is buried.

Scope of application

• Municipal Potable Water Mainlines and Distribution In municipal infrastructure projects, these ISO 4427 compliant PE100 pipes serve as the primary conduits for high-pressure potable water transmission. The system is engineered for trunk lines and urban distribution networks, handling treated drinking water at ambient temperatures. Its certified non-toxic composition (NSF/WRAS approved) ensures that water quality is maintained from the treatment plant through to residential service connections, effectively eliminating non-revenue water (NRW) losses caused by joint leakages.
• Agricultural Irrigation and Rural Water Schemes Designed to withstand the hydraulic surges common in large-scale agricultural irrigation systems, these pipes are used for long-distance water transport in rural areas. They are suitable for pumping stations and gravity-fed systems delivering raw water or filtered irrigation water to farmland. The UV-stabilized material allows for surface-laid or shallow-buried installations in varied terrains, maintaining structural integrity under high-intensity sunlight and fluctuating outdoor temperatures.
• Industrial Process Water and Chemical Fluid Transport Within the chemical, petroleum, and metallurgical sectors, HDPE water supply pipelines are utilized for the transportation of process water, cooling water, and mild acidic or alkaline solutions. The material's chemical inertness makes it suitable for industrial environments where metal pipes would suffer from rapid electrochemical corrosion. It is frequently employed in factory utility systems to handle fluids with pH values ranging across the standard industrial spectrum at consistent operational pressures.
• Mining Operations and Tailings Management In demanding mining environments, these heavy-duty pipes are used for mine dewatering and the transportation of abrasive slurries or process fluids. The high fracture toughness of the PE100 material allows the pipeline to adapt to shifting ground conditions and the high-impact stresses found in mineral processing facilities. Whether used for permanent underground installations or temporary surface lines, the system ensures reliable fluid management in high-load industrial working conditions.
• Trenchless Infrastructure and HDD Projects Leveraging the high stress-crack resistance of PE100RC (Resistance to Crack) materials, these pipes are specifically suitable for Horizontal Directional Drilling (HDD) and pipe bursting applications. This non-excavation method is used for river crossings or installing water mains under existing roadways without disturbing the surface. The pipe's ability to resist point loading and scratches during the pulling process ensures a safe, high-pressure-rated installation even in challenging soil conditions containing gravel or debris.
• Fire-Fighting Water Supply Networks These high-pressure HDPE pipes are utilized in dedicated fire-fighting loops for industrial parks and commercial complexes. Rated up to PN25, the system provides the necessary pressure capacity (SDR 11 or SDR 7.4) required for fire hydrant systems and sprinkler supply lines. The corrosion-free nature of the pipe ensures that the internal diameter remains constant over decades, guaranteeing that critical flow rates are available during emergency discharge scenarios.
