The PVC-U water supply pipe is mainly made of PVC resin, with the addition of special additives, and is formed by extrusion through an extruder. This pipe has good sealing at the interface, an attractive appearance, is sturdy and durable, and the material is hygienic, causing no pollution to water quality. The inner wall is smooth and has a large water transmission capacity. Corrosion-resistant, with a long service life, it is lightweight for convenient transportation and easy construction. It has excellent pressure resistance (0.1MPa-4.0MPa), can withstand temperatures ranging from -30℃ to +60℃, and will not harden or soften the pipe body due to changes in climate or usage temperature.

UPVC Water Pipe (unplasticized polyvinyl chloride water pipe) is extruded from high-quality PVC resin with special additives. It features hygienic material, smooth inner walls, and exceptional durability, complying with the "Safety Evaluation Standard for Drinking Water Distribution Equipment and Protective Materials" (GB/T 17219).
This pipe boasts a nominal pressure range of 0.1MPa-4.0MPa and temperature resistance from -30℃ to +60℃. With a roughness coefficient of 0.008-0.009, it ensures low flow resistance, while its tensile strength at 23℃ is no less than 45MPa, guaranteeing structural stability.
Made of food-grade PVC resin without plasticizers. Its vinyl chloride monomer (VCM) content is below 5mg/kg, avoiding secondary water pollution and algae/bacteria growth.
Total lifecycle cost is over 40% lower than traditional metal pipes. No anti-corrosion treatment is needed, and maintenance costs are only 30% of cast iron or concrete pipes.
Low water transmission resistance cuts energy consumption by 15%-20%. Waste pipes are recyclable, aligning with low-carbon construction concepts.
Resists acids, alkalis, salts, and stray currents, suitable for complex environments like municipal buried projects. It offers a long service life without hardening or softening.
