Our advanced PVC pressure systems are extensively utilized for drinking water, recycled water, sewage management, and gas distribution. These systems ensure safe and reliable transportation, making them indispensable across a diverse range of applications.
At DHPI, we take immense pride in manufacturing a comprehensive range of superior-quality PVC pressure pipes and fittings. By leveraging the finest raw materials and industry-leading best practices, we deliver products that consistently set the standard for excellence.
PVC-UH, an enhanced version of PVC-U, is available in a variety of colors tailored for specific applications such as water mains, water supply, recycled water, irrigation, and pressure sewerage. These pipes come in standard 6m lengths featuring spigot and socket ends designed for rubber ring jointing (RRJ), ensuring a seamless and secure connection.
Introducing our groundbreaking pressure sewage drainage pipe, engineered with a revolutionary online built-in integrated forming steel skeleton sealing connection structure. This innovation ensures quick and effortless installation, guaranteeing optimal installation quality and leak-tight connections. By fundamentally addressing joint leakage issues, our product ensures zero leakage in pipe network operations and unmatched strength.
The high-performance PVC-UH water supply pipe is crafted with an integrally formed steel skeleton sealing connection structure. This design guarantees exceptional connection reliability and tightness, significantly enhancing the pipe's mechanical properties. Our pipes boast high strength, superior pressure tolerance, and remarkable ring stiffness, making them ideal for outdoor buried installations and pipe gallery setups.
Exceptional Environmental Adaptability: The enhanced toughness of our pipelines enables them to effectively withstand point loads and uneven foundation settlements, making them suitable for non-standard constructions and challenging working conditions.
Outstanding Chemical Corrosion Resistance: Our pipes resist corrosion from a vast range of media, ensuring that soil substances do not degrade the pipeline. With a lifespan of ≥50 years, our pipes promise long-term reliability.
Superior Hydraulic Performance: Designed 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.
