PVC pressure systems have become the backbone of modern infrastructure, finding extensive application in drinking water supply, recycled water management, sewage systems, and gas distribution.
At DHPI, we take immense pride in manufacturing a comprehensive range of top-tier PVC pressure pipes and fittings. We employ only the finest raw materials and follow best practices within the industry, ensuring unmatched quality and durability.
PVC-UH, an advanced version of PVC-U, offers a multitude of color options tailored for various applications. Its primary uses include watermains, water supply, recycled water, irrigation, and pressure sewerage. These pipes come in standard 6m lengths with spigot and socket ends designed for rubber ring jointing (RRJ).
Introducing an innovative pressure sewage drainage pipe featuring an online built-in integrated forming steel skeleton sealing connection structure. This ensures quick and convenient installation while guaranteeing joint tightness and eliminating leakage issues, thus achieving zero leakage in pipeline networks. These high-strength products set a new benchmark in the industry.
Our high-performance PVC-UH water supply pipe is engineered with an integrally formed steel skeleton that ensures superior connection reliability and tightness. The pipe's design significantly enhances its mechanical properties, offering high strength, pressure resistance, and ring stiffness. Ideal for outdoor buried applications and pipeline gallery installations.
Boasting exceptional environmental adaptability, our pipeline's enhanced toughness effectively withstands point loads and uneven foundation settlements, making it ideal for non-standard constructions and challenging working conditions.
Exhibiting excellent chemical corrosion resistance, these pipes can withstand a variety of corrosive media. The durable construction ensures that soil substances do not degrade the pipeline, guaranteeing a lifespan of 50 years or more.
Featuring outstanding hydraulic performance, our pipes adeptly absorb impact energy caused by water pressure fluctuations. This capability enhances the pipeline's resistance to water hammer, reduces operational risks, improves water supply efficiency, and lowers operating costs.
