PVC-U Pipe for Non-Pressurized Buried Sewage and Drainage
Product Introduction:
The PVC-U pipe for non-pressurized buried sewage and drainage is produced by extrusion molding using polyvinyl chloride resin as the main raw material and adding necessary additives to form a compound. According to different connection methods, the pipe can be divided into elastic sealing ring connection pipes and adhesive connection pipes. Considering the chemical resistance and heat resistance of the material, PVC-U pipes for non-pressurized buried sewage and drainage can also be used as industrial drainage pipes.
