Our PVC pressure systems are the epitome of versatility, extensively utilized for drinking water, recycled water, sewage, and gas distribution, ensuring reliable performance across diverse applications.
At DHPI, we take immense pride in manufacturing a broad spectrum of superior-quality PVC pressure pipes and fittings. Employing only the finest raw materials and industry-leading best practices, we ensure unparalleled reliability and durability.
PVC-UH represents an advanced evolution of PVC-U, available in a variety of colors tailored to specific applications. This versatile product primarily serves Watermains, Water supply, Recycled water, Irrigation, and Pressure sewerage systems. Our pipes come in standard 6m lengths, featuring spigot and socket ends for seamless rubber ring jointing (RRJ).
Our innovative pressure sewage drainage pipe boasts an integrated steel skeleton sealing connection structure, facilitating swift and straightforward installation. This ensures impeccable installation quality and connection tightness, effectively eliminating pipeline joint leakage and achieving zero-leakage operations. The product also offers exceptional strength and durability.
The high-performance PVC-UH water supply pipe is designed with an integrally formed steel skeleton that guarantees connection reliability and tightness. Enhanced mechanical properties such as high strength, high pressure, and superior ring stiffness make this pipe ideal for outdoor buried installations and pipe gallery paving.
With outstanding environmental adaptability, our pipeline's enhanced toughness effectively resists point loads and uneven foundation settlement. It adapts to non-standard construction conditions and challenging working environments with ease.
Exemplary chemical corrosion resistance allows our pipeline to withstand various corrosive media. The substances in the soil do not degrade the pipeline, ensuring a lifespan of ≥50 years.
Our pipes exhibit superior hydraulic performance by absorbing impact energy from water pressure fluctuations, enhancing resistance to water hammer, minimizing operational risks, improving water supply efficiency, and cutting down operational costs.
