Explore material families used for outer centering rings where gasket alignment, compression control, corrosion conditions and operating environment determine material choice.
Explore Grades →Choose the centering-ring material according to installation, corrosion exposure and service requirements.
Stainless steel outer rings provide corrosion resistance and durable centering-ring performance for compatible industrial services.
View Material Data →Carbon steel outer rings are widely used for compatible general industrial service where project corrosion requirements permit.
View Material Data →Duplex stainless steel outer rings provide higher strength and improved chloride-related corrosion resistance for suitable environments.
View Material Data →Nickel and special-alloy outer rings are considered where unusually aggressive corrosion or service conditions require them.
View Material Data →Outer-ring material should support correct installation and remain suitable for the expected external and process environment.
The outer ring provides centering and helps position the gasket correctly between mating flanges.
Consider the role of the centering ring in installation and gasket compression control.
Account for atmospheric, wash-down, external and any relevant process-related corrosion exposure.
Consider handling, temperature, pressure, cycling and project material requirements.
