Description
PN10/16 Backing Rings manufactured from galvanised mild steel are used to provide the mechanical strength required for flanged connections in Corzan CPVC pipework systems. Installed behind a CPVC stub flange, the backing ring allows controlled bolt tightening while maintaining joint integrity under pressure.
The galvanised steel construction delivers high rigidity and durability, while the protective zinc coating helps resist corrosion in industrial environments. When used alongside a CPVC stub flange and suitable gasket, the backing ring assists in evenly distributing bolt loads across the flange face, reducing the risk of distortion and leakage.
Designed to PN10 and PN16 drilling patterns in accordance with BS / EN flange standards, these backing rings integrate seamlessly into European-standard flanged CPVC installations.
