Our PVC pressure systems are extensively utilized for a variety of applications, including potable water, recycled water, sewage, and gas distribution.
At DHPI, we take immense pride in our extensive range of premium PVC pressure pipes and fittings. Crafted from the finest raw materials and adhering to industry-best practices, our products exemplify superior quality and reliability.
PVC-UH represents a significant advancement over traditional PVC-U. Available in a spectrum of colors for various uses, these pipes are predominantly employed in water mains, water supply, recycled water, irrigation, and pressure sewerage. Supplied in standard 6m effective lengths with spigot and socket ends, they ensure seamless and secure rubber ring jointing (RRJ).
Introducing our innovative pressure sewage drainage pipe, which features an online built-in integrated forming steel skeleton sealing connection structure. This design facilitates quick and easy installation, guaranteeing superior installation quality and connection tightness. This solution fundamentally eliminates pipeline joint leakage, ensuring zero leakage during pipe network operation. The product boasts high strength and reliability.
Our high-performance PVC-UH water supply pipe leverages an integrally formed steel skeleton for sealing the connection structure, ensuring unrivaled reliability and tightness. The advanced design significantly enhances the pipe's mechanical properties, offering benefits like high strength, high pressure, and superior ring stiffness. Ideal for outdoor buried installations and pipe gallery applications, it stands out in performance and durability.
Exceptional environmental adaptability: The enhanced toughness of our pipeline allows it to effectively resist point loads and accommodate uneven foundation settlements. It excels in non-standard construction environments and demanding working conditions.
Outstanding chemical corrosion resistance: Our pipes can withstand corrosion from various media, ensuring that soil substances do not degrade the pipeline. With a lifespan of 50 years or more, it offers long-lasting performance.
Superior hydraulic performance: The pipeline efficiently absorbs impact energy from water pressure fluctuations, enhancing its ability to resist water hammer. This reduces operational risks, enhances water supply efficiency, and significantly cuts down operating costs.
