Product Description

 

Our PVC pressure systems are revolutionizing the industry, providing reliable solutions for drinking water, recycled water, sewage, and gas distribution. Discover how our advanced technology ensures superior performance for all your water and gas needs.
At DHPI, we take pride in manufacturing an extensive array of premium PVC pressure pipes and fittings. Our commitment to using only the highest quality raw materials and industry-leading practices guarantees exceptional and enduring results.

Introducing our advanced PVC-UH range, an upgraded solution to traditional PVC-U. Available in various colors to suit different applications, it excels in water mains, water supply, recycled water, irrigation, and pressure sewerage. Each pipe is supplied in standard 6m lengths with spigot and socket ends for efficient rubber ring jointing (RRJ).

Presenting our innovative pressure sewage drainage pipe, featuring an integrated steel skeleton sealing connection. This design ensures fast and easy installation, superior connection tightness, and eliminates joint leakage, delivering a zero-leakage pipe network with unmatched strength.

 

Our high-performance UPVC water supply pipe boasts an integrally formed steel skeleton for superior sealing and connection reliability. The enhanced design significantly boosts the pipe's mechanical properties, offering high strength, pressure, and ring stiffness, ideal for outdoor and gallery installations.

 

Unmatched Environmental Adaptability: Our pipelines exhibit exceptional toughness, effectively resisting point loads and uneven foundation settlement. They adapt seamlessly to non-standard construction and challenging conditions, proving their worth in the toughest environments.
Exceptional Chemical Corrosion Resistance: Our pipes resist a variety of corrosive media, ensuring that soil substances do not degrade the pipeline. With a lifespan of over 50 years, our pipelines promise long-term reliability and durability.
Superior Hydraulic Performance: Our pipes absorb the impact energy from water pressure fluctuations, boosting resistance to water hammer. This enhancement reduces operational risks, improves water supply efficiency, and lowers operating costs, ensuring optimal performance.
