We take PVC resin as the main raw materials, add suitable amount of additives, produce drainage rigid polyvinyl chloride (PVC-U) pipe by mixing, extruding, sizing, cooling, cutting, etc. Drainage injection pipe fittings take PVC resin as the main raw materials, add suitable amount of additives, injection molding after mixing.
According to GB/T5836.1-92 and GB/T5836.2-92 standard, Jiangsu Piersa, with advanced equipment, adopts its unique and excellent craft formula to produce 40-200mm building drainage pipe series, and provides matching drainage injection pipe fittings series products.
Drainage PVC-U pipe is mainly used for building drainage, life wastewater or water-polluter discharge, drainage system of municipal engineering, factories and mines, enterprises, etc. It's the new building materials mainly promoted by country instead of cast iron pipe and cement.
1, PVC-U pipes and pipe fittings have excellent Physico-chemical property, high impact strength, small fluid resistance. Compared with cast iron pipe of same diameter, its flow is increased by 30%, it has good aging resistance, and its normal service life can reach more than 50 years.
2, Excellent corrosion resistant performance against inorganic acid, alkali and alt, suitable for industrial wastewater discharge and transportation.
3, Small friction coefficient, unhindered water flow, it's not easy to jam, less maintenance workload.
4, The pipes linear expansion coefficient is 0.07 mm/m, the temperature deformation is small. Coefficient of thermal conductivity and elasticity modulus is small, good freezing resistance compared with cast iron drainage pipe.
5, pipe and pipe fitting can use adhesive connection, simple construction method and easy operation can effectively speed up the construction schedule, and can reduce the construction cost.
6, save construction cost, the comprehensive cost of PVC-U pipes and pipe fittings is lower than the same specifications cast iron pipe system.
7, the material oxygen index is high, so it has the self-extinguishing.
8, Our products mainly are white, it's color and luster is bright, it's smooth and flat.
