UPVC Pipe Manufacturer

UPVC pipe is made of polyvinyl chloride(PVC) resin as the main raw material, adding the necessary additives to form a mixture, plasticized and extruded into a PVC-U sheet with a locking structure on the outside, and then made into single-layer, double-layer and multi-layer spiral winding pipe by winding technology.

Product Features

1. UPVC pipes are impact-resistant, friction-resistant, water-tight, stable in performance, and highly resistant to acid and alkali;
2. UPVC pipes are light in weight, easy to transport, and less affected by seasonal climate;
3. Plastic PVC pipe connectors are few and simple to connect;
4. Flexible UPVC pipe rings are flexible, allowing large deformation and uneven settlement of the foundation, with large ring force, allowing pipe-soil co-seismicity.
5. The surface roughness coefficient of UPVC pipes is 0.009, with fast flow rate. Under the same pipe diameter and slope, its water-passing capacity is 1.4 times that of cement pipes;
6. UPVC pipes do not pollute soil and groundwater sources, and waste pipes can be completely recycled.

Application Areas

1. Unpressurized underground buried industrial sewage pipe;

2. Municipal drainage sewage pipes;

3. External drainage of buildings;

4. Rainwater collection and Domestic sewage discharge;

5. Expressway construction.
