Our premium PVC pressure systems are indispensable for a diverse range of applications, including potable water, recycled water, sewage, and gas distribution. These systems are the backbone of reliable and efficient fluid transportation.
At Shandong Donghong Pipe Industry Co., Ltd. (DHPI), we take immense pride in our meticulously crafted range of high-quality PVC pressure pipes and fittings. Our relentless commitment to excellence ensures we use only top-tier raw materials and the most advanced manufacturing practices in the industry. This dedication guarantees the durability and reliability you can trust.
Our PVC-UH pipes signify a remarkable advancement from conventional PVC-U. Available in a spectrum of colors tailored for specific uses, these pipes excel in watermains, water supply, recycled water systems, irrigation, and pressure sewerage solutions. Each pipe is furnished in standard 6-meter lengths, with spigot and socket ends for efficient rubber ring jointing (RRJ), ensuring flawless connectivity and installation.
Presenting our revolutionary pressure sewage drainage pipe, engineered with an innovative built-in steel skeleton sealing connection structure. This design ensures rapid and straightforward installation, superior installation quality, and robust connections, effectively eradicating joint leakage and guaranteeing a zero-leakage operation. These pipes are distinguished by their high strength and reliability.
Our high-performance PVC-UH water supply pipes feature a robust integrally formed steel skeleton, ensuring superior connection reliability and tightness. The avant-garde design significantly enhances the mechanical properties, providing exceptional strength, high-pressure tolerance, and outstanding ring stiffness. They are ideal for outdoor buried ground installations and pipe galleries.
Unmatched Environmental Adaptability: Our pipes showcase remarkable toughness, effectively countering point loads and uneven foundation settlements. Perfectly suited for non-standard construction and the most demanding working conditions, our pipes excel in adaptability and reliability.
Outstanding Chemical Corrosion Resistance: Our pipes are engineered to resist a wide spectrum of media corrosion, ensuring that substances in the soil do not compromise the pipeline. Designed for endurance, our pipes have a lifespan exceeding 50 years, providing long-term reliability.
Superior Hydraulic Performance: Our pipes adeptly absorb the impact energy from water pressure fluctuations, enhancing their ability to withstand water hammer. This improves operational safety, boosts water supply efficiency, and reduces operating costs, offering a compelling combination of performance and value.
