Description
This mild steel backing ring is designed for use in conjunction with PVC or ABS stub flanges to provide the mechanical strength required for bolted flanged connections. While the stub flange forms the sealing face, the backing ring distributes bolt loads evenly, ensuring a secure and stable joint when used with compatible gaskets and bolt sets.
Manufactured from mild steel and finished with a protective coating, the backing ring offers durability and strength in pressure-rated flange assemblies. Its rotating design allows for easier bolt alignment during installation, reducing assembly time and improving overall ease of use. Commonly used across water treatment, chemical handling, manufacturing, and general industrial pipework, mild steel backing rings are an essential component of PVC or ABS flanged joint systems.
