Description
ANSI 150 Backing Rings manufactured from galvanised mild steel are used to provide the mechanical strength required for bolted flanged connections in Corzan CPVC pipework systems. Installed behind a CPVC stub flange, the backing ring allows uniform bolt tightening and ensures the integrity of the flange joint under pressure.
The galvanised steel construction offers excellent rigidity while providing surface protection against corrosion in industrial environments. When paired with a CPVC stub flange and appropriate gasket, the backing ring helps distribute bolt loads evenly, reducing the risk of flange distortion and leakage.
Designed to ANSI 150 flange drilling standards, these backing rings are ideal for applications where ANSI-rated flange connections are specified, particularly in chemical processing, industrial water and effluent systems.
