PVC-UH Water Supply Pipe: Mastering Trench Excavation and Backfill Quality
1. Ensure compliance with trench excavation standards for optimal results
To safeguard against pipelines being laid in permafrost areas, accurately determine the depth of trench excavation by considering comprehensive local data. Proper backfill operation and tamping are essential to avoid pipeline and interface cracking due to bending stresses, making it crucial that:
(1) Trench alignment is straight. The trench's bottom width must exceed the pipe's outer diameter by at least 0.5m, with a total width of no less than 0.7m to ensure adequate space and stability.
(2) Control the trench groove's depth meticulously to prevent deviations. Over-deep gravel requires backfilling to the designated depth. In areas with hard soil and encountered obstacles, such as stones, construction teams might resort to curving the trench or reducing the curve radius. Failure to maintain trench depth can result in post-laying pipe bends, causing undue bending stress on pipes, fittings, and joint sockets. Increased water supply pressure amplifies risks of joint leakage or pipe and fitting rupture.
2. Counter permafrost foundation and pipe trench settlement risks. During winter construction, ensure the pipe trench's base rests on undisturbed soil or compacted ground post-grooving. High soil moisture and loose foundations risk permafrost melting with warming temperatures, leading to trench sinking, pipe bending, and joint breakage, inducing additional stress. Minor shifts may pull apart joints, causing leaks; severe shifts risk pipe rupture.
3. Winter Pipeline Bonding - Adhering to Essential Regulations
PVC-UH tube adhesive consists primarily of PVC-UH solvent. The bonding process involves applying adhesive to the inner socket surface and the outer socket surface, causing the PVC-UH-polyurethane tube's surfaces to expand or dissolve. During socket insertion, extrusion pressure fuses the expanded surfaces. The adhesive's solvent evaporates easily, returning the dissolved surface to a solid state, ensuring bonding strength that meets pressure requirements.
Precision in adhesive application is crucial. Insufficient adhesive compromises seal integrity and strength, whereas excess adhesive spreads along pipe walls during insertion, causing corrosion, softening, and potential cracking under water pressure. Low-temperature conditions exacerbate these issues, slowing adhesive evaporation and deepening wall penetration, significantly weakening pipe strength.
Adherence to specification requirements in bonding pipe construction is vital. The bonding agent's volume should be sufficient for a slight overflow at the interface upon socket insertion. Clean any excess adhesive with a cloth. Apply glue within the socket from the inside out to prevent inner wall contamination.
4. Understanding Pipe Thermal Expansion and Contraction Dynamics
PVC-UH water supply pipe features a thermal expansion coefficient of 0.07mm (m·ºC), surpassing that of traditional pipes. Attention to elongation from temperature variations is imperative, particularly in water delivery systems using surface water sources.
The innovative design of the rubber ring connecting pipe interface offers an unparalleled advantage due to its remarkable scalability. While bonded pipes, including open-ended ones, present a challenge with their rigid interfaces post-bonding, this is not a concern with our advanced system. Without an expansion joint, traditional pipes may suffer from intense stress during expansion or contraction. However, our solution ensures the stress does not impact the pipe or its fittings, providing peace of mind and long-lasting durability.
Our versatile pipe connection methods include solvent adhesive, elastic sealing rings, and the integrated rubber ring connection, ensuring seamless integration. For those requiring connection with other pipe types, such as cast iron pipes, our system easily adapts using flanges or other suitable adapters, guaranteeing a robust and reliable connection every time.
Follow our streamlined connection program: clean the working face meticulously, apply a generous brush of lubricant, and ensure a smooth counterpart insertion. This method promises ease and efficiency, optimizing the installation process.
1. Prior to installation, conduct a thorough quality check of pipes, fittings, and rubber rings. Clean the working face of both the socket and plug to ensure flawless installation.
2. Expert tip for installation: position the socket to face the direction of incoming water, optimizing flow and ensuring optimal performance.
3. Carefully apply lubricant to both the rubber ring and insertion part. Use just the right amount to prevent overflow into the socket groove. This minimizes friction between the rubber ring and groove wall, preventing any overturning. We recommend using detergent and soapy water as lubricants for best results.
4. Meticulously align the socket ports and maintain a straight pipeline axis to ensure precision and efficiency in installation.
5. Securely place wire rope sleeves on either side of the socket and employ a tightener or hand wrench to pull them into the reticle. For medium-caliber pipes, utilize square wood to pad the port, gently tapping the socket with a mallet for a snug fit.
