with inner ring
The inner ring also serves several functions. Primarily, it provides radial support for the gasket on the I.D. to help prevent the occurrences of buckling or imploding. Its I.D. is normally sized slightly larger than the I.D. of the flange bore, minimizing turbulence in process flow. The inner rings are normally supplied in the same material as the spiral .
There are many advantages to using an inner ring: Additional Compression Stop. Additional Blowout Resistance. Prevents Build Up of Process Fluid. Minimizes Erosion and Turbulence. Shields the Gasket. Prevents Buckling.
