Introducing our enhanced PVC-UH pipes, an upgraded version of PVC-U. Available in a spectrum of colors for distinct applications, these pipes are primarily used for water mains, water supply, recycled water, irrigation, and pressure sewerage. Each pipe is provided in standard 6-meter lengths with spigot and socket ends for efficient rubber ring jointing (RRJ).
Discover our revolutionary pressure sewage drainage pipe, featuring an innovative built-in steel skeleton sealing connection structure. This design ensures rapid and easy installation, guaranteeing superior connection integrity and zero leakage. Perfectly engineered for robustness and high strength, this pipe elevates the standard of pipeline joint reliability.
Our cutting-edge PVC-UH water supply pipe boasts an integrally formed steel skeleton, ensuring a secure and tight connection. The advanced design significantly enhances the pipe's mechanical properties, offering high strength, pressure resistance, and exceptional ring stiffness, making it ideal for outdoor buried installations and pipe gallery applications.
Exceptional environmental adaptability: Our pipes exhibit remarkable toughness, effectively withstanding point loads and uneven foundation settlement. They are designed to adapt seamlessly to non-standard constructions and the most challenging working conditions.
Superior chemical corrosion resistance: These pipes can endure a variety of corrosive media, ensuring that substances in the soil do not degrade the pipeline. With a lifespan of ≥50 years, our pipelines offer long-term reliability and peace of mind.
Outstanding hydraulic performance: Our pipes proficiently absorb impact energy caused by water pressure fluctuations, enhancing their ability to withstand water hammer effects. This leads to reduced operational risks, improved water supply efficiency, and lower operating costs.
