Description
This stub flange is designed to be solvent-welded directly onto PVC pipe, forming the flanged end of a bolted joint when used in conjunction with a backing ring, gasket and bolt set. The stub flange itself provides the sealing face, while the backing ring delivers the mechanical strength required for bolting.
Manufactured from PVCu, it offers excellent resistance to corrosion, chemical attack, and scaling, making it suitable for a wide range of industrial environments. Once solvent-welded to the pipe, the stub flange creates a strong, permanent connection that integrates seamlessly into flanged pipework systems. Stub flanges are commonly used in water treatment, chemical processing, manufacturing, and general industrial installations where flanged connections are required for valves, pumps, or equipment interfaces.
