PVC-UH is an enhanced variant of PVC-U, available in multiple colors to suit specific applications such as water mains, water supply, recycled water, irrigation, and pressure sewerage. These pipes are produced in standard 6m lengths with spigot and socket ends, designed for rubber ring jointing (RRJ) to ensure a seamless and secure connection.
Introducing our revolutionary pressure sewage drainage pipe, engineered with an innovative online built-in integrated forming steel skeleton sealing connection structure. This cutting-edge design ensures quick and effortless installation, guaranteeing optimal installation quality and leak-tight connections. By fundamentally addressing joint leakage issues, our product ensures zero leakage during pipe network operations, combined with unmatched strength.
The high-performance PVC-UH water supply pipe is crafted with an integrally formed steel skeleton sealing connection structure. This advanced design guarantees exceptional connection reliability and tightness, significantly enhancing the pipe's mechanical properties. Our pipes offer high strength, superior pressure tolerance, and remarkable ring stiffness, making them ideal for outdoor buried installations and pipe gallery setups.
Exceptional Environmental Adaptability: Our pipelines feature enhanced toughness, allowing them to effectively withstand point loads and uneven foundation settlements. This makes them suitable for non-standard constructions and challenging working conditions.
Outstanding Chemical Corrosion Resistance: Our pipes are resistant to corrosion from a wide range of media, ensuring that soil substances do not degrade the pipeline. With a lifespan of ≥50 years, our pipes provide long-term reliability and durability.
Superior Hydraulic Performance: Engineered to absorb impact energy from water pressure fluctuations, our pipes enhance resistance to water hammer, reduce operational risks, improve water supply efficiency, and lower operating costs.
