PVC-UH represents a significant upgrade over traditional PVC-U. Available in various colors for specific applications, these pipes are ideal for Watermains, Water supply, Recycled water, Irrigation, and Pressure sewerage. Each pipe comes in standard 6-meter effective lengths, featuring spigot and socket ends designed for rubber ring jointing (RRJ).
Introducing our groundbreaking pressure sewage drainage pipes, which feature an online built-in integrated forming steel skeleton sealing connection. This design ensures quick and easy installation, guaranteeing connection tightness and eliminating joint leakage for zero-leakage pipeline operation. These products boast exceptional strength.
Our high-performance PVC-UH water supply pipes incorporate an integrally formed steel skeleton for enhanced connection reliability and tightness. The advanced product design significantly boosts the pipe's mechanical properties, offering high strength, high pressure, and superior ring stiffness. These pipes are perfect for outdoor buried installations and pipe gallery applications.
Unmatched environmental adaptability: Our pipes' enhanced toughness effectively resists point loads and uneven foundation settlement, making them ideal for non-standard constructions and challenging work conditions.
Superior chemical corrosion resistance: Our pipes can withstand various corrosive media, ensuring that soil substances do not degrade the pipeline. With a lifespan of over 50 years, they are a long-term investment in reliability.
Exceptional hydraulic performance: Our pipes effectively absorb impact energy from water pressure fluctuations, enhancing water hammer resistance, reducing operational risks, increasing water supply efficiency, and lowering operating costs.
