PVC-UH is a premium evolution of PVC-U, available in multiple colors for various uses. Ideal for Watermains, Water supply, Recycled water, Irrigation, and Pressure sewerage. These pipes come in standard 6m lengths with spigot and socket ends for quick and secure rubber ring jointing (RRJ).
Introducing an innovative pressure sewage drainage pipe featuring an online built-in steel skeleton sealing connection structure. This design guarantees fast and convenient installation, ensuring superior installation quality and connection tightness. It addresses pipeline joint leakage issues, providing a zero-leakage operation with high strength.
Our high-performance PVC-UH water supply pipe incorporates a seamlessly formed steel skeleton within its connection structure, ensuring unmatched reliability and tightness. This design significantly enhances the pipe's mechanical properties, offering high strength, high pressure resistance, and exceptional ring stiffness, making it ideal for outdoor buried installations and pipe gallery applications.
Exceptional Environmental Adaptability: Our pipelines boast significant toughness, effectively resisting point loads and accommodating uneven foundation settlement. They are designed to handle non-standard construction and demanding working conditions.
Superior Chemical Corrosion Resistance: These pipes can withstand corrosion from a wide range of media, ensuring that soil substances will not degrade the pipeline. They are engineered for a lifespan of 50 years or more.
Outstanding Hydraulic Performance: Our pipes proficiently absorb the impact energy from water pressure fluctuations, enhancing their resistance to water hammer. This results in reduced operating risks, improved water supply efficiency, and lower operating costs.
