Trench Excavation Standards for PVC-O Water Supply Pipes and Optimal Backfill Soil Quality
1. Ensure that trench excavation for our PVC-O Water Supply Pipes is executed with precision, adhering to the highest industry benchmarks for seamless installation success.
Determining the trench excavation depth is vital, especially to avoid permafrost layers. Analyze local geological data to guide this process, ensuring efficient backfilling. Correct execution here prevents pipeline and interface cracking due to bending stress, thus maintaining the integrity of your pipeline system. Key considerations include:
(1) Trenches must be crafted with precision, ensuring straightness with a bottom width at least 0.5m wider than the pipe's outer diameter. The total width should not be less than 0.7m, providing optimal stability for your installation.
(2) Maintain exacting bottom depth standards. Avoid excessive gravel by compacting backfill to necessary levels. In areas with hard soil or obstacles, gentle curves are permissible, but ensure consistent depth to prevent stress on pipes and joints, which could lead to leakage or rupture under increased pressure.
2. Guard against permafrost-related issues by ensuring trenches rest on stable, undisturbed soil or well-compacted backfill. High soil moisture can result in permafrost melting and trench settlement, leading to pipe issues such as sinking, bending, or joint breakage. Minor misalignments may cause leaks, while serious shifts can result in ruptures.
3. Winter pipeline bonding requires strict adherence to all established protocols to ensure durable connections.
Our PVC-O tube adhesive, with its advanced composition of PVC-O solvent, facilitates effective bonding. The application to both surfaces leads to slight expansion, allowing for seamless fusion under extrusion pressure. The solvent's quick volatilization solidifies the bond, ensuring it meets all pressure requirements for robust performance.
Precision in adhesive application is crucial. A balanced amount ensures a strong seal without compromising integrity. Overuse can lead to corrosion and softness, causing potential cracks under stress. In cold conditions, slow volatilization could weaken the pipe wall.
Meticulous bonding is vital. Adhere to specifications rigorously. Minimal overflow during socket insertion must be addressed promptly. Apply adhesive from the socket's interior outward to prevent internal contamination.
4. Considerations for Thermal Expansion and Contraction of Pipes
With a thermal expansion coefficient of 0.07 mm per meter per ºC, our PVC-O pipes experience greater expansion than traditional materials. Manage temperature-induced deformation, especially in systems with surface water sources.
The adaptable rubber ring interface efficiently mitigates expansion and contraction concerns. However, for bonded pipes, post-adhesion rigidity may challenge flexibility. Without expansion joints, this rigidness can exert significant pressure, affecting pipe structure or fittings.
Our pipes offer a versatile world of connection methods, including solvent adhesive, elastic sealing ring, and integrated rubber ring options. They seamlessly connect with other pipe types, like cast iron, through flanges or adapters, offering comprehensive piping solutions.
Effortless Connection Program: Begin by ensuring a meticulously clean working face ---- Generously apply lubricant ---- Ensure precise insertion for optimal performance.
1. Before installation, thoroughly check the quality of pipes, fittings, and rubber rings. A spotless working face on both the socket and counterpart is essential for a flawless assembly.
2. During installation, strategically align the socket towards incoming water flow, enhancing system efficiency and reliability.
3. Generously apply lubricant to both the rubber ring and the insertion section. While ensuring the lubricant is used in moderation to prevent it from seeping into the socket groove, this crucial step effectively reduces the friction between the rubber ring and the groove wall, thus safeguarding against any potential overturning of the rubber ring. We highly recommend using detergent and soapy water as lubricants for optimal performance and seamless installation results.
4. Carefully align the socket ports, ensuring that the pipeline axis remains perfectly straight. This meticulous alignment is essential to guaranteeing the stability and structural integrity of the entire system, providing a seamless and robust connection.
5. Equip both sides of the socket with appropriate wire rope sleeves and employ a tightener (or hand wrench) to securely pull them into the reticle. For medium-caliber pipes, strategically place square wood at the port and gently knock it into the socket with a mallet for a precise and secure fit, ensuring impeccable installation and long-lasting durability.
