PVC pressure systems are widely used for drinking water, recycled water, sewage and gas distribution.
DHPI prides itself on manufacturing a comprehensive range of quality PVC pressure pipes and fittings, using only the finest raw materials and best practices within the industry.
PVC-UH is an upgraded product of PVC-U. A range of colors for different applications is available. The main use applications are water mains, water supply, recycled water, irrigation, and pressure sewerage. Pipes are supplied in standard 6m effective lengths with spigot and socket ends for rubber ring jointing (RRJ).
Introducing our innovative pressure sewage drainage pipe, featuring an online built-in integrated forming steel skeleton sealing connection structure for fast and convenient installation. This design ensures superior installation quality and connection tightness, effectively solving the problem of pipeline joint leakage to achieve zero leakage pipe network operation. The product boasts high strength.
Our high-performance PVC-UH water supply pipe utilizes an integrally formed steel skeleton to seal the connection structure, ensuring reliable and tight connections. The design greatly enhances the mechanical properties of the pipe, offering advantages such as high strength, high pressure, and high ring stiffness. It is ideal for outdoor buried ground applications and installation in pipe galleries.
Strong environmental adaptability: The pipeline's improved toughness effectively resists point loads and uneven foundation settlements, making it suitable for non-standard construction and demanding working conditions.
Excellent chemical corrosion resistance: The pipeline can withstand corrosion from a variety of media, and substances in the soil will not degrade it. The pipeline's lifespan is ≥50 years.
Superior hydraulic performance: The pipe effectively absorbs impact energy caused by water pressure fluctuations, enhancing its resistance to water hammer, reducing operational risks, improving water supply efficiency, and lowering operating costs.
