Crafted for superior performance, these advanced rigid polyvinyl chloride (PVC-UH) water supply pipes are engineered from premium polyvinyl chloride polymer materials, enhanced with essential additives. With an impressive MRS ≥ 25Mpa, these pipes are precisely extruded and molded to perfection. As a groundbreaking advancement in water supply piping, they significantly enhance the mechanical properties and connectivity compared to traditional PVC-U and PVC-M pipes.
The PVC-UH water supply pipe revolutionizes the field with its enhanced molecular chain structure, offering exceptional strength and pressure endurance. It boasts ring stiffness, excellent internal and external pressure capabilities, making it ideal for pipe gallery installations. With outstanding toughness, a high modulus, minimal shrinkage, and over 45% ring flexibility, it excels in impact resistance, adeptly handling material stress due to temperature fluctuations in pipe galleries. Integrated plastic inspection wells assure superior pressure sealing, guaranteeing system integrity. Simplified installation and swift construction translate to low maintenance costs, while the pipeline system guarantees a design life exceeding 50 years. This remarkable product delivers a low-investment, high-value solution with unparalleled cost-effectiveness.

Excavation and Backfill Standards for pvc-uh Water Supply Pipes: A Guide to Excellence
1. Trench Excavation: Adhere to Gold Standards for Optimal Performance.
To ensure flawless installation, trenches must avoid permafrost layers. Local data analysis is crucial to determine the precise excavation depth. The backfill process should uphold strict compaction standards to prevent pipeline and interface stress, thus averting potential cracking.
(1) Precision in Trench Alignment: The trench must be perfectly straight, with a bottom width exceeding the outer pipe diameter by at least 0.5m. Ensure a total width of no less than 0.7m for stability.
(2) Depth Control is Essential: Maintain consistency in the trench's bottom depth. In cases of excessive gravel depth, backfill and compact to meet specifications. Encountering hard soil or obstacles like stones might tempt constructing curved trenches or shallow depths, increasing construction ease but risking post-laying pipe bending. Such stress can lead to joint leakage or rupture when water pressure surges.
2. Safeguard Against Permafrost and Trench Settling: During winter projects, ensure the trench's base rests on undisturbed soil or compacted ground post-grooving. High moisture content and loose foundations risk thawing-induced settlement and subsequent pipe bending, joint breakage, and leakage or rupture.
3. Adhere to Winter Bonding Regulations for Optimal Pipeline Integrity
The primary ingredient of the pvc-uh tube adhesive is pvc-uh solvent. Its bonding method involves applying adhesive to both the socket's inner surface and the fitting's outer surface, prompting expansion or dissolution. During insertion, extrusive pressure fuses these surfaces, and the volatile nature of the solvent aids the process. Once evaporated, the material hardens without compromising substrate strength, ensuring robust pressure resistance.
Apply adhesive with precision-neither scant nor excessive. Insufficient amounts fail to secure sealing or strength; excess adhesive might corrode or soften pipe walls, risking cracks under pressure. Low temperatures slow evaporation, deepening penetration, and weakening pipe strength.
Thus, apply bonding agents strictly per specifications. After socket insertion, minimal overflow of the bonding agent is ideal and should be swiftly wiped. Glue application should start from the socket's interior, preventing inward flow to pipe walls.
4. Consideration for Thermal Expansion and Contraction
The thermal expansion coefficient of PVC-uh pipes, at 0.07mm (m · ºC), surpasses traditional pipes. Vigilant monitoring of longitudinal deformation due to temperature shifts is crucial, especially when surface water sources are involved.
The adaptable nature of the rubber ring connecting interface eliminates concerns of expansion or contraction. In stark contrast, bonded pipes, particularly those exposed, form a rigid bond that cannot flex. Without an expansion joint, these pipes and fittings endure immense stress from thermal changes, which directly impacts their integrity.
Our versatile pipe connection methods include solvent adhesive, elastic sealing ring, and seamless integrated rubber ring connections. Moreover, adaptability is key, as our pipes can effortlessly connect to various other types, such as cast iron pipes, using specialized flanges or suitable adapters.
Seamless Connection Procedure: Thoroughly clean the working surface, brush on lubricant generously, and proceed with precise insertion for a perfect fit.
1. Prior to installation, rigorously inspect the quality of pipes, fittings, and rubber rings. Ensure the socket and socket surfaces are meticulously clean to guarantee an impeccable connection.
2. During installation, position the socket to face the oncoming water flow, optimizing system performance and longevity.
3. Carefully apply a lubricant to the rubber ring and its insertion section. Ensure the appropriate amount is used to prevent overflow into the socket groove, which could destabilize the rubber ring. Use mild detergent or soapy water for optimal lubrication.
4. Align the socket ports meticulously, ensuring the pipeline axis remains perfectly straight for flawless operation.
5. Securely position suitable wire rope sleeves on either side of the socket. Utilize a tightener or hand wrench to draw them into the reticle. For medium-sized pipes, place square wood padding at the port and gently tap into the socket using a mallet for a seamless fit.
