Above class 600 an internal ring is recommended.

Flexitallic Gasket Style CGI Style CGI
A Style CG gasket fitted with internal ring which gives an additional compression limiting stop, and provides heat and corrosion barrier, protecting gasket windings and preventing flange erosion.

Flexitallic Gasket Style R Style R
Basic construction type. Inner and outer diameters are reinforced with several plies of metal without filler to give greater stability and better compression and sealing characteristics.
Suitable for tongue and groove or male and female for grooved to flat face flange assemblies.

Flexitallic Gasket Style RIR Style RIR
Solid inner metal ring acts as a compression stop and fills the annular space between flange bore and the inside diameter. Designed to prevent accumulation of solids, reduce turbulent flow of process fluids and minimize erosion of flange faces.
