Smooth inner wall PVC-O water supply pipes are high-performance polyvinyl chloride water supply pipes formed by bidirectional axial orientation process and with high-precision ultra-smooth inner wall processing. They combine the high strength, lightweight, and high pressure resistance of PVC-O pipes with the low resistance water transmission advantage of ultra-smooth inner wall, greatly reducing water head loss. They are suitable for long-distance, high-pressure, and high-flow water transmission scenarios and can be used indoors and outdoors for buried/exposed installation. They are the preferred pipe material for efficient and energy-saving water transmission in municipal, industrial, and construction fields. Food-grade versions are also suitable for drinking water transmission.
1. Made with specialized PVC-O resin as the base material, formed using a bidirectional axial orientation process, the tube body molecules are densely arranged along the axis and circumference, combining high strength and high toughness. The thin-walled, lightweight design uses less material and is lighter in weight for the same pressure resistance rating.
2. The inner wall undergoes high-precision polishing/molding treatment, resulting in an ultra-smooth surface without burrs or unevenness, uniform diameter, and low surface energy. The outer wall can be customized for wear resistance and other properties depending on the application. 3. UV-cured and corrosion-resistant, seamlessly integrated molding eliminates the risk of peeling.
4. Available in a full range of diameters (DN50~DN400), with clearly defined pressure ratings (1.6~4.0MPa), flexibly adaptable to engineering needs of varying water supply scales and pressures. High pipe roundness and precise dimensions.
5. Equipped with dedicated sealing connectors, ensuring smooth, non-jamming interfaces that create a continuous, smooth water flow channel without localized flow resistance. Sanitary connectors are available for drinking water applications.
6. The inner wall is resistant to scaling and impurities. The sanitary version uses food-grade base materials and additives, preventing the release of harmful substances and meeting the hygiene requirements for drinking water distribution.
7. Highly adaptable to different installation scenarios, accommodating slight ground subsidence and small curvature curves. Stable flow patterns are maintained in both buried and exposed installations.
1. Exceptionally High Hydraulic Water Conveying Efficiency: The inner wall friction coefficient is significantly lower than that of ordinary UPVC, PE pipes, and conventional PVC-O pipes, greatly reducing head loss during long-distance, high-flow water transport, improving pipeline water conveying efficiency, reducing pump boosting energy consumption, and achieving significant energy savings;
2. Superior Mechanical Properties: Tensile, compressive, and impact strengths are 2-3 times that of ordinary UPVC pipes. High ring stiffness can withstand soil compression, heavy ground compaction, and construction impacts without deformation or damage. The thin-walled design does not affect structural stability;
3. Stable Pressure Resistance and Water Conveying: Working pressure can reach... 1.6~4.0MPa, meeting the pressure requirements of municipal high-pressure long-distance water transmission, industrial high-flow process water transmission, and secondary water supply for high-rise buildings, with no risk of pipe bursting, leakage, or bulging during long-term operation;
4. Excellent scale and fouling resistance and hygiene: Low inner wall surface energy, not prone to scale buildup, sediment adhesion, or bacterial growth, ensuring no decrease in water transmission efficiency over long periods; food-grade version meets national drinking water hygiene standards, with no heavy metal or plasticizer leaching, safe for drinking water transportation;
5. Wide weather and corrosion resistance and adaptability: operating temperature range - 15℃~70℃, suitable for all scenarios of cold water transportation and distribution at normal temperature; outdoor exposed installation resists UV aging, does not powder or crack; buried installation withstands soil acidity, alkaliness, salt, and weak groundwater corrosion, does not swell or age;
6. Reliable sealing and seepage prevention: Equipped with dedicated smooth interface connectors, the sealing structure ensures zero leakage, avoiding water waste and preventing underground mud and impurities from seeping into the pipe, eliminating secondary pollution of the water medium. There are no dead zones at the interface, and it does not affect the overall hydraulic efficiency;
7. Long service life and aging resistance: The pipe body has a dense and stable molecular structure with excellent fatigue and aging resistance. Its designed service life can reach more than 50 years under various water transportation conditions, eliminating the need for frequent dredging and replacement, resulting in low maintenance costs.
1. Municipal Long-Distance High-Efficiency Water Transmission: Construction of main/branch pipes for water supply and drainage in new urban areas, upgrading and renovation of pipe networks in old urban areas, high-pressure, high-flow cold water transmission and distribution across urban areas, and long-distance municipal drinking water transmission projects, maximizing the advantages of low resistance and energy saving;
2. Drinking Water Transmission and Distribution Projects: Buried/exposed transmission and distribution of municipal drinking water pipe networks and rural centralized drinking water projects, high-rise secondary water supply risers and indoor/outdoor high-flow drinking water pipes in large residential communities and high-end commercial complexes, with sanitary-grade standards to ensure water quality;
3. Industrial High-Efficiency Water Supply and Drainage: Long-distance, high-flow transmission and distribution of high-pressure cooling water, process cold water, and circulating cold water in industrial plants, and non-corrosive miscellaneous water pipe networks in chemical, light industry, and manufacturing industries, improving industrial water transmission efficiency and reducing production energy consumption;
4. Large Building Water Supply and Drainage: Indoor/outdoor high-flow cold water transmission and distribution in super high-rise office buildings, large commercial complexes, and cultural and tourism parks.
