Drinking-grade UPVC water supply pipes are special water pipes for domestic drinking water, made of food-grade modified UPVC substrate. They meet the hygiene standards for drinking water transmission and distribution, have no harmful substances released, do not pollute water quality, and have the characteristics of pressure-resistant water transmission, sealing and seepage prevention, and indoor and outdoor use. The inner wall is smooth and not easy to scale, and the construction is convenient. They are high-performance drinking water transmission and distribution pipes for municipal water supply, indoor drinking water in buildings, and rural drinking water projects.
1. Made with food-grade modified UPVC base material, lead-free and free of toxic plasticizers, ensuring drinking water safety from the raw material stage;
2. Pressure-resistant solid wall structure, primarily medium and low diameter (DN20~DN110), suitable for conventional water supply pressures in residential/municipal drinking water systems;
3. High-precision smooth treatment of inner and outer walls, preventing bacterial growth and scaling on the inner wall, and ensuring the outer wall is resistant to minor friction, with a straight and regular pipe body;
4. Equipped with drinking water-specific sealing connectors, using adhesive/socket connections for a high degree of fit, leak-proof, and no unsanitary corners;
5. Scenario-specific modified design: indoor models include moisture-resistant and mildew-proof additives, while outdoor/buried models include UV-resistant and soil corrosion-resistant additives;
6. Lightweight and highly rigid, easy to cut and transport, requiring no specialized heavy equipment, adaptable to flexible needs of indoor and outdoor pipe network laying.
1. Hygiene and Safety Compliance: Meets national hygiene standards for drinking water transmission and distribution pipes, with no harmful substances leaching out or emitting odors, ensuring no water pollution during long-term water transmission;
2. Stable Pressure Resistance and Water Transmission: Operating pressure reaches 0.6~1.0MPa, meeting the conventional pressure requirements of municipal water supply and building indoor water supply, eliminating the risk of pipe bursts or bulging;
3. Excellent Hydraulic Performance: Smooth inner wall with low friction coefficient, reducing head loss and improving water transmission efficiency, while also preventing scaling and bacterial growth, ensuring smooth water transmission over the long term;
4. Weather and Corrosion Resistance: Suitable for various operating temperatures - 10℃~70℃; Indoor concealed installation is moisture-resistant and mildew-free; Outdoor exposed installation resists UV aging; Buried installation is resistant to mild acid and alkali corrosion from the soil.
5. Reliable sealing and seepage prevention: Specialized connectors ensure zero leakage at pipe section connections, avoiding water waste and preventing external mud, water, and impurities from contaminating the drinking water inside the pipes.
6. Excellent basic mechanical properties: Resistant to minor impacts and sand/gravel friction during construction; Buried installations can withstand static soil loads without deformation or damage, ensuring the integrity of the pipeline network.
1. Core Guarantee of Drinking Water Safety: Both the base material and fittings are drinking water-grade, eliminating unsanitary areas and protecting drinking water quality from the distribution stage, unlike ordinary UPVC water pipes;
2. Outstanding Cost-Effectiveness: Raw material, construction, and post-construction maintenance costs are significantly lower than drinking water-grade pipes such as stainless steel and PPR, making it suitable for large-scale drinking water network construction;
3. Convenient and Efficient Construction: Easy to cut, quick to form with adhesive/socket connections, can be done manually without professional welding/heat fusion equipment, suitable for indoor and outdoor decentralized laying scenarios;
4. Long-Term Maintenance-Free Use: The inner wall is not prone to scaling, and the outer wall is corrosion-resistant and anti-aging, eliminating the risk of coating peeling. After laying, frequent cleaning and replacement are not required, significantly reducing pipeline operation and maintenance costs;
5. Wide Adaptability: Can meet various drinking water distribution needs, including concealed installation in buildings, underground installation in municipal areas, and exposed installation in rural courtyards, adapting to different climates in the north and south;
6. Long-Term Stable Water Delivery Efficiency: The smooth inner wall's scale-free characteristic ensures that the pipeline's water delivery efficiency does not significantly decrease over the long term, reducing water supply energy consumption.
1. Municipal Water Supply: Buried drinking water transmission and distribution networks in urban communities and towns, and branch pipe installation for drinking water in residential buildings;
2. Indoor Water Supply: Indoor cold water pipes for residences, office buildings, hotels, and apartments, and terminal water supply for kitchens, bathrooms, and balconies;
3. Rural Drinking Water Projects: Buried water transmission networks for centralized water supply projects in new rural areas, and installation of drinking water pipes for natural villages and households;
4. Public Building Water Supply: Distribution of drinking water in public places such as schools, hospitals, supermarkets, and stadiums, ensuring public drinking water hygiene and safety;
5. Small Water Supply Station Distribution: Construction of pipeline networks from drinking water sources to users in small water supply stations in towns, communities, and scenic areas;
6. Villa/Courtyard Water Supply: Indoor and outdoor drinking water pipeline networks for private villas and courtyards, and branch water supply for direct drinking water and domestic water use in courtyards.
