Reliable PVC Pipe for Global Supply Water Applications 6 Meters

Our premium-grade rigid polyvinyl chloride (PVC-O) water supply pipes are masterfully engineered using top-of-the-line polyvinyl chloride polymer materials, expertly enhanced with essential additives to deliver exceptional performance. With an impressive MRS ≥ 25Mpa, these pipes are meticulously extruded and flawlessly molded, setting a new standard as a pioneering solution in the water supply pipe industry. This revolutionary innovation significantly elevates the mechanical properties and fortifies the durability of both the pipes and their connections, transcending the capabilities of traditional PVC-U and PVC-M pipes.
The PVC-O water supply pipe showcases an advanced molecular chain structure of polyvinyl chloride, offering unparalleled high strength and pressure endurance. Featuring outstanding ring stiffness and exceptional resilience to both internal and external pressure, it is perfectly suited for pipe gallery installations. Boasting impressive toughness, a high modulus, and minimal shrinkage, it provides over 45% ring flexibility, ensuring superb impact resistance. The pipe expertly manages material stress release due to temperature variations in the pipe gallery, and includes built-in plastic inspection wells with superior high-pressure sealing to guarantee a leak-proof pipeline system. Its straightforward installation and rapid construction substantially decrease maintenance costs, while promising a design life exceeding 50 years. This culminates in a low investment yet remarkably cost-effective solution for all your water supply requirements.

Trench Excavation Standards for PVC-O Water Supply Pipes and Optimal Backfill Soil Quality
1. Trench excavation must adhere to high industry standards to ensure success.
To prevent pipelines from being laid within permafrost layers, it's crucial to determine trench excavation depth by considering and summarizing local geological data. This ensures efficient backfill operations, essential for preventing pipeline and interface cracking due to bending stress. Here are the key requirements:
(1) Trenches must be meticulously straight, with the bottom width not less than the pipe's outer diameter plus 0.5m, ensuring a total width of no less than 0.7m for optimal stability.
(2) Rigorously maintain precise bottom depth-neither too deep nor too shallow. In cases of excessive gravel depth, backfill and compact to the specified levels. In areas encountering hard soil or obstacles, such as stones, trenches may curve slightly to facilitate construction. Ensure curves are gentle and depth is consistent to prevent pipe bending, which causes undue stress on the pipe, fittings, and joints. Increased water supply pressure can result in joint leakage or rupture.
2. Avoid permafrost-related foundation issues and potential trench settlement. During winter, ensure that pipe trenches rest on undisturbed soil or well-compacted backfilled ground. High soil moisture content can cause future permafrost melt and trench settlement, leading to pipe sinking, bending, and joint breakage with increased stress. Minor issues may cause joint separation and leaks, while severe cases lead to rupture.
3. Winter pipeline bonding must strictly follow established regulations.
PVC-O tube adhesive, primarily composed of PVC-O solvent, functions by applying adhesive to the socket's inner and outer surfaces. This causes expansion or dissolution in the PVC-O-polyurethane tube's surface, allowing extrusion pressure to unite these surfaces during socket insertion. The adhesive's solvent easily volatilizes, reverting the dissolved surface to a solid state, maintaining substrate strength and ensuring bonding strength meets pressure requirements.
Adhesive quantity should be precisely controlled-neither too scant to compromise sealing and strength, nor excessive, which may flow along pipe walls, corroding and softening them. Overuse leads to cracking under water or pressure. In cold conditions, slowed adhesive volatilization increases penetration, weakening the pipe wall.
Adhere strictly to specification requirements for bonding pipe construction. Ensure adhesive application results in minimal overflow when the socket is inserted, which should be promptly cleaned off. Apply glue from the socket interior outward to avoid unwanted flow into the pipe internals.
4. Considerations for Thermal Expansion and Contraction of Pipes
With a thermal expansion coefficient of 0.07mm (m · ºC), PVC-O water supply pipes expand more than traditional materials. Account for temperature-induced longitudinal deformation, especially in systems utilizing surface water sources.
Owing to the versatile scalability of the rubber ring connecting pipe interface, the issue of expansion or contraction is effortlessly mitigated. However, when it comes to bonded pipes-especially the open type-post-bonding, the interface becomes rigid, lacking flexibility. Without installing expansion joints, the immense pressure from expansion or contraction could severely impact the pipe structure or fittings.
Explore a world of connection methods with our pipes, offering the flexibility of solvent adhesive, elastic sealing ring, and integrated rubber ring connections. Moreover, these pipes seamlessly connect to other varieties such as cast iron pipes through the use of flanges or other compatible adapters, providing a comprehensive solution for diverse piping needs.
Effortless Connection Program: Begin by cleaning the working face meticulously ---- Next, apply a lubricant generously ---- Finally, ensure a precise counterpart insertion for optimal performance.
1. Prior to installation, meticulously verify the quality of pipes, fittings, and rubber rings. Ensure the working face of both the socket and its counterpart are spotless and ready for a seamless assembly.
2. During installation, position the socket strategically towards the direction of incoming water flow, optimizing the system's efficiency and reliability.
3. Generously apply an ample amount of lubricant to both the rubber ring and the insertion section. It is crucial to ensure that the lubricant is used sparingly, as over-application can lead to it seeping into the socket groove, which we want to avoid. By taking this precaution, we significantly reduce friction between the rubber ring and the groove wall, effectively preventing any potential overturning of the rubber ring. For optimal performance, we highly recommend detergents and soapy water as your lubricants of choice.
4. Carefully align the socket ports with precision, ensuring the pipeline axis remains perfectly straight. This meticulous alignment is vital in guaranteeing unmatched stability and structural integrity, essential for dependable performance.
5. Equip both sides of the socket with appropriate wire rope sleeves and employ a tightener (or hand wrench) to pull them securely into the reticle. For medium-caliber pipes, place square wood at the port and gently knock it into the socket with a mallet for a precise and perfect fit. This ensures a robust connection and superior alignment.
