Potable grade PVC-M water supply pipe is a high-toughness modified PVC drinking water pipe made of food-grade special resin via modified toughening technology. It is professionally designed for domestic drinking water transmission and distribution scenarios.
On the premise of ensuring drinking water safety and no harmful substance precipitation, it greatly improves the pipe’s impact resistance, low-temperature resistance and bending resistance. Compared with ordinary potable UPVC pipes, it is more suitable for complex working conditions such as slight ground settlement and construction collision. It can be used for indoor and outdoor buried / exposed installation, and is the preferred high-toughness pipe for drinking water pipeline network construction.
Adopts food-grade dedicated PVC-M base material, matched with lead-free calcium-zinc sanitary stabilizer. It contains no toxic plasticizers or heavy metal additives, eliminating drinking water pollution from the raw material source without sanitary dead corners.
Professionally modified and toughened with high toughness and low brittleness as core performance. Different from the rigid and fragile ordinary UPVC pipes, the pipe body withstands slight bending and extrusion and is not easy to crack.
Thin-wall lightweight design. Under the same pressure rating, its wall thickness is equivalent to potable UPVC pipe. It saves raw materials, features light weight, and is easy for transportation, manual handling and on-site construction, suitable for laying in narrow spaces such as household inlet pipes.
Inner and outer walls adopt high-precision smooth treatment. The inner wall has low surface energy, preventing scaling and bacterial growth; the outer wall resists slight gravel friction. Outdoor / buried types are modified with high UV resistance and weak soil corrosion resistance, integrally formed without coating peeling risk.
Supporting sanitary PVC-M fittings specially for drinking water. Sealing rings are made of food-grade nitrile rubber / silicone rubber. The socket connection structure is anti-seepage and anti-disengagement, forming a continuous water flow channel with no water stagnation dead corners.
Diameter covers mainstream specifications of drinking water projects (dn20~dn315) with clear pressure grades. It can flexibly build a complete pipeline network of water mains, branch pipes and household inlet pipes, featuring high roundness and precise dimensional tolerance.
Sanitary & Safe Compliance
No harmful substances precipitate during long-term water conveyance, and it does not change the color, taste and quality of drinking water. It meets drinking water sanitary requirements through immersion tests and is safe for domestic drinking water delivery.
High Toughness & Impact Resistance
Impact strength is 2~3 times that of ordinary potable UPVC pipes. It remains crack-free under low-temperature impact at -10℃, resists construction collision and gravel impact, and withstands extrusion deformation caused by slight ground settlement after burial.
Pressure Resistant & Stable Water Delivery
Working pressure ranges from 0.6 to 1.6 MPa, meeting conventional pressure demands of municipal water supply, building indoor water supply and rural drinking water projects. No pipe bursting, leakage or bulging during long-term operation.
High Hydraulic Transmission Efficiency
Smooth inner wall with low friction coefficient greatly reduces head loss in long-distance water delivery and improves conveying efficiency. The inner wall is not easy to scale or adhere impurities, maintaining stable hydraulic performance long-term.
Wide Weather & Corrosion Resistance
Applicable temperature: -10℃ ~ 70℃, suitable for normal-temperature drinking water transmission in northern and southern regions. Concealed indoor installation resists moisture and mildew; modified exposed outdoor type anti-UV aging; buried laying withstands weak acid, alkali and salt soil corrosion.
Reliable Sealing & Anti-seepage
Food-grade sealing rings matched with sanitary fittings realize zero leakage at joints. It avoids drinking water loss and blocks infiltration of underground muddy water and sewage, preventing secondary water pollution.
Excellent Installation Adaptability
The pipe body has proper flexibility. When buried, it adapts to trench routes with small curvature radius without using a large number of additional elbows, improving construction efficiency. It is ideal for drinking water pipeline laying in complex geological areas such as countryside and mountainous regions.
