Our versatile PVC pressure systems are extensively employed across various sectors, including drinking water supply, recycled water management, sewage systems, and gas distribution networks.
At DHPI, we take immense pride in crafting an extensive array of premium PVC pressure pipes and fittings. Utilizing only the finest raw materials and adhering to the highest industry standards, we ensure unmatched quality.
PVC-UH, an advanced iteration of PVC-U, comes in a variety of colors tailored for specific applications. Primarily used for water mains, water supply, recycled water, irrigation, and pressure sewerage, these pipes are available in standard 6m lengths with spigot and socket ends, facilitating efficient rubber ring jointing (RRJ).
Introducing our cutting-edge pressure sewage drainage pipe, featuring an innovative online built-in integrated forming steel skeleton sealing connection structure. This design accelerates and simplifies installation, guarantees superior connection quality, and ensures joint tightness, thereby eliminating leakage issues and achieving zero-leakage pipeline operation. This product boasts remarkable strength.
The high-performance PVC-UH water supply pipe is engineered with an integrally formed steel skeleton, enhancing the reliability and tightness of the connections. Its design significantly boosts the pipe's mechanical properties, offering high strength, high pressure tolerance, and exceptional ring stiffness. Ideal for outdoor buried installations and pipe gallery setups.
Remarkable environmental adaptability: The pipeline's enhanced toughness effectively counters point loads and uneven foundation settlement, making it suitable for non-standard construction and challenging working conditions.
Outstanding chemical corrosion resistance: These pipes can withstand a variety of corrosive media, and soil substances won't degrade them. This ensures a pipeline life expectancy of ≥50 years.
Superior hydraulic performance: Our pipes adeptly absorb impact energy from water pressure fluctuations, enhancing the pipeline's resistance to water hammer. This improves operational reliability, boosts water supply efficiency, and reduces operating costs.
