Our PVC-UH pipes represent a significant leap forward from traditional PVC-U. Available in an array of vibrant colors tailored for specific applications, these pipes are perfect for watermains, water supply, recycled water systems, irrigation, and pressure sewerage solutions. Each pipe is supplied in standard 6-meter lengths, featuring spigot and socket ends for efficient rubber ring jointing (RRJ), ensuring seamless connectivity and superior performance.
Introducing our groundbreaking pressure sewage drainage pipe, meticulously designed with an innovative built-in steel skeleton sealing connection structure. This ensures quick and easy installation, superior installation quality, and tight connections, effectively eliminating joint leakage and guaranteeing a zero-leakage operation. These pipes boast unparalleled strength and reliability.
Our high-performance PVC-UH water supply pipes feature a robust integrally formed steel skeleton, guaranteeing superior connection reliability and tightness. The advanced design significantly enhances the mechanical properties, providing exceptional strength, high pressure handling, and superior ring stiffness. These pipes are ideally suited for outdoor buried ground installations and pipe galleries, ensuring long-lasting durability.
Unmatched Environmental Adaptability: Our pipes exhibit remarkable toughness, effectively countering point loads and uneven foundation settlements. They are perfectly suited for non-standard construction projects and the most demanding working conditions.
Outstanding Chemical Corrosion Resistance: Our pipes are adept at resisting a wide range of media corrosion, ensuring that substances in the soil do not degrade the pipeline. Designed for longevity, our pipes boast a lifespan of over 50 years, providing reliable performance for decades.
Superior Hydraulic Performance: Our pipes adeptly absorb the impact energy from water pressure fluctuations, significantly enhancing their ability to withstand water hammer. This results in improved operational safety, increased water supply efficiency, and reduced operating costs.
