PVC pressure systems are extensively utilized for an array of applications, including drinking water, recycled water, sewage, and gas distribution. Their versatility and reliability make them an essential component in modern infrastructure.
At DHPI, we take immense pride in crafting a wide-ranging assortment of premium PVC pressure pipes and fittings. We employ only the highest-quality raw materials and adhere to industry-best practices, ensuring our products stand out in performance and durability.
PVC-UH, a progressive enhancement of PVC-U, comes in various colors to suit different 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 for reliable rubber ring jointing (RRJ).
Our latest innovative pressure sewage drainage pipes feature an advanced built-in steel skeleton sealing connection design. This ensures quick and easy installation, superior seal integrity, and completely eradicates joint leakage issues, delivering a zero-leakage pipe network with exceptional strength.
The high-performance PVC-UH water supply pipe showcases an integrally formed steel skeleton for robust connection reliability and tightness. The design significantly enhances the pipe's mechanical properties, offering high strength, pressure, and ring stiffness. Perfect for outdoor buried installations and pipe gallery applications.
Unmatched environmental adaptability: The pipeline's enhanced toughness effectively withstands point loads and uneven foundation settlement, adapting seamlessly to non-standard construction and challenging working conditions.
Superior chemical corrosion resistance: Capable of withstanding corrosion from various media, the pipeline remains unaffected by soil substances, ensuring a lifespan of 50 years or more.
Exceptional hydraulic performance: The pipe efficiently absorbs energy from water pressure fluctuations, enhancing its resistance to water hammer, minimizing operational risks, boosting water supply efficiency, and reducing operational costs.
