This PVC-U water supply pipe adopts food-grade PVC resin and sanitary formula, which is specially designed for urban and rural drinking water transmission, secondary water supply system and industrial pure water pipeline to create safe and reliable solutions. The product has passed the certification of pressure-resistant grade PN16, which can withstand internal pressure of 1.6MPa, and the temperature-resistant range is from - 10℃ to 60℃, which is suitable for long-term and stable operation under different climatic conditions. Its hot-melt socket connection technology realizes leak-free sealing, and the inner wall smoothness Ra≤0.2μm reduces scale deposition, which significantly improves the water quality protection ability.PVC-U water supply pipe has passed the international certification of NSF/ANSI 61, and the material has no heavy metal precipitation, and the UV aging-resistant performance extends the outdoor service life to more than 50 years. The outer wall adopts spiral reinforcement design to enhance compressive strength, and the seismic resistance has passed GB/T 18042 test, adapting to the pipeline laying needs of earthquake-prone areas.PVC-U water supply pipe supports non-excavation repair technology to reduce the construction cost, and the modularized fittings adapt to diversified installation scenarios, which is widely used in urban residential districts, commercial complexes, and the construction of municipal water supply network.PVC-U water supply pipe is widely used in residential district, commercial complexes, and municipal water supply network construction. With the advantages of sanitary formula and heat fusion socket connection, PVC-U water supply pipe continues to provide efficient protection for safe drinking water projects.
