PVC-U drainage pipes

1. Hard polyvinyl chloride is a hard material without plasticizers. The surface sensitivity and tensile strength of pipes are excellent, and the pressure resistance level and pipeline safety factor are high.2. UPVC has good aging resistance, and its normal service life can reach more than 50 years.3. The pipeline has excellent corrosion resistance to various inorganic acids, alkalis, and salts, and is suitable for the discharge and transportation of various industrial wastewater.4. The friction coefficient of the pipeline is small, the water flow is smooth, it is not easy to block, and the maintenance workload is small.5. The material has a high oxygen index and is classified as a B2 grade flame resistant material with self extinguishing properties.6. The linear expansion coefficient of the pipeline is small, 0.07mm/m. ℃, and the deformation amount is small due to temperature influence. It is 100%~130% lower than similar polyolefin materials, with small thermal conductivity and elastic modulus. Compared with cast iron drainage pipes, it has excellent frost resistance.7. Adhesion can be used for the connection of pipes and fittings, with simple construction methods, convenient operation, and high installation efficiency.
