PVC pressure systems are indispensable for modern infrastructure, serving crucial roles in the distribution of drinking water, recycled water, sewage, and gas. Their versatility and reliability make them a preferred choice across various sectors.
At DHPI, we take immense pride in crafting an extensive and high-quality array of PVC pressure pipes and fittings. Our commitment to excellence ensures we employ only premium raw materials and adhere to best industry practices, guaranteeing superior performance and durability.
PVC-UH represents a significant advancement over traditional PVC-U, offering a variety of colors tailored for specific applications, including Watermains, Water supply, Recycled water, Irrigation, and Pressure sewerage. These pipes come in standard 6m lengths with spigot and socket ends designed for secure rubber ring jointing (RRJ).
Introducing a cutting-edge pressure sewage drainage pipe featuring an innovative built-in steel skeleton sealing connection structure. This design facilitates fast and convenient installation while ensuring superior connection quality and tightness. It effectively resolves pipeline joint leakage issues, achieving zero leakage and high operational strength for the pipe network.
Our high-performance PVC-UH water supply pipe incorporates an integrally formed steel skeleton that enhances connection reliability and tightness. This design significantly boosts the mechanical properties of the pipe, offering advantages such as high strength, high pressure tolerance, and excellent ring stiffness. Ideal for outdoor buried installations and pipe gallery applications.
Exceptional environmental adaptability: The improved toughness of our pipeline allows it to effectively resist point loads and uneven foundation settlements. It is designed to adapt to non-standard construction scenarios and more demanding operational conditions.
Outstanding chemical corrosion resistance: Our pipelines can withstand corrosion from various media, ensuring that soil substances will not degrade them. With a lifespan of 50 years or more, these pipelines promise longevity and reliability.
Superior hydraulic performance: Our pipes efficiently absorb impact energy from water pressure fluctuations, enhancing their ability to resist water hammer. This improves water supply efficiency, reduces operational risks, and lowers overall operating costs.
