Audited Supplier Audited by an independent third-party inspection agency
Crafted with excellence, our high-performance rigid polyvinyl chloride (PVC-UH) water supply pipes are a testament to advanced engineering. These pipes are fabricated using premium-grade polyvinyl chloride polymer materials, enhanced with essential additives to achieve superior strength. With an impressive MRS ≥ 25Mpa, our pipes are carefully extruded and molded, representing a revolutionary solution for water supply needs. Elevating the traditional PVC-U and PVC-M pipes, these innovative pipes significantly enhance mechanical properties, ensuring robust and reliable connections that stand the test of time.
Our elite PVC-UH water supply pipes redefine durability and performance by optimizing the molecular chain structure of polyvinyl chloride. This enhancement provides exceptional strength, superior pressure resistance, and remarkable ring stiffness, making it the ideal choice for pipe gallery installations. With excellent internal and external pressure stability, these pipes boast outstanding toughness and a high modulus, minimizing shrinkage and offering over 45% ring flexibility. They are designed to withstand impacts and efficiently manage material stress due to temperature fluctuations. Featuring built-in plastic inspection wells, they deliver high-pressure sealing capabilities, ensuring a watertight system. The ease of installation and swift construction contribute to low maintenance costs. Our pipeline system promises a lifespan exceeding 50 years, delivering unparalleled cost-effectiveness and minimal initial investment for your secure water transport needs.

PVC-UH Water Supply Pipe Trench Excavation Standard: Elevate your endeavors with premium backfill soil quality.
1. Trench excavation should comply with standards to ensure safety and reliability.
To maintain the integrity of your pipeline system and avoid the complications of permafrost layer intrusion, determine your trench depth by evaluating comprehensive local data. Proper backfill operations are crucial to prevent pipeline and interface cracking due to bending stress. Thus, it is essential to:
(1) Ensure the trench is straight. The bottom width must exceed the pipe's outer diameter by at least 0.5m, and the total width should be no less than 0.7m to secure stability.
(2) Precisely control the groove depth-avoid it being too deep or too shallow. In cases of excessive gravel depth, backfill and compact to the desired depth. Encountering hard soil or obstacles like stones can complicate trenching, leading to unintentional curves or insufficient depth, which may cause pipe bending. This bending can induce stress on pipe joints and sockets, posing risks of leakage or ruptures under rising pressure or water supply.
2. Safeguard against permafrost foundations and trench settlement. During winter construction, ensure the pipe trench rests on undisturbed soil, or on compact ground post-backfilling. High soil moisture without a dense foundation can lead to permafrost melting and trench foundation sinking as temperatures rise. Such conditions result in pipe bending and joint breakage, creating stress that potentially leads to joint separation and leaks, or in severe cases, pipe rupture.
3. Winter pipeline bonding should be strictly regulated to meet industry standards.
The PVC-UH tube adhesive, primarily composed of PVC-UH solvent, works by applying adhesive to the inner socket surface and outer socket surface. This process expands or dissolves the PVC-UH-polyurethane tube surfaces, allowing them to merge into one solid entity under extrusion pressure during socket insertion. Quick solvent volatilization solidifies the surface, maintaining substrate strength and ensuring bonding strength meets pressure requirements.
Use the correct adhesive amount, as excess or deficiency can compromise sealing or strength. Overuse leads to adhesive flowing along the pipe walls, causing corrosion and softening, increasing the likelihood of cracks during water delivery or pressurization. Low temperatures slow adhesive volatilization, risking deeper penetration into the pipe wall, which significantly reduces strength.
Adhere strictly to specification requirements for bonding pipes. Apply enough bonding agent so a little overflows from the interface when the socket is inserted, then clean any excess with a cloth. Apply glue from the inside out to prevent inward leaks.
4. Address thermal expansion and contraction challenges for optimal performance.
The thermal expansion coefficient of PVC-UH water supply pipes, at 0.07mm (m · ºC), surpasses that of traditional pipes. Pay close attention to longitudinal deformation from thermal fluctuation, especially in water delivery systems sourcing from surface water.
Elevate your piping systems with our cutting-edge solution, designed to adapt seamlessly to your diverse needs. While conventional bonded pipes and open pipes pose challenges with their rigid interfaces, our advanced PVC pipe technology, complete with a rubber ring connecting interface, ensures scalability and unrivaled flexibility. Experience the liberation from stress-induced warping or damage due to expansion or contraction, as our product eliminates the need for cumbersome expansion joints, delivering unparalleled reliability and durability.
Discover the versatility in connection methods with our PVC pipes, engineered to cater to your specific requirements. Choose from solvent adhesive options, elastic sealing rings, or the seamless integrated rubber ring connection. Our pipes are equipped to adapt to any environment, effortlessly connecting to various pipe types, including cast iron, through the use of expertly designed flanges and adapters that ensure a secure and efficient fit every time.
Streamline your connection process with our straightforward program: meticulously clean the working face-apply an optimal layer of lubricant-execute the precise counterpart insertion. This method ensures a seamless, efficient, and durable connection, making installation a breeze.
1. Ensure flawless installation by first conducting a thorough inspection of the quality of pipes, fittings, and rubber rings. Meticulously clean the working face of both the socket and the socket to guarantee a pristine surface for installation, ensuring longevity and performance.
2. For optimal installation efficiency, orient the socket to face the direction of incoming water, facilitating smooth fluid dynamics and maximizing efficiency in water transportation.
3. Achieve a seamless fit by applying a generous yet controlled amount of lubricant to both the rubber ring and the insertion part. Carefully apply to prevent excess from entering the socket groove, minimizing friction and preventing any chance of the rubber ring overturning. Utilize high-quality lubricants such as detergent or soapy water to ensure a smooth, frictionless connection.
4. Align socket ports with precision to maintain a perfectly straight pipeline axis, ensuring optimal flow and system integrity.
5. Securely position suitable wire rope sleeves on either side of the socket. Employ a tightener or hand wrench to methodically pull them into the reticle. For medium-caliber pipes, strategically use square wood to pad the port and gently tap it into the socket with a mallet, achieving a secure fit.
