Centering ring
The centering ring does not come into direct contact with contained fluid. It is effective to avoid corrosion.
Inner ring
Inner ring is used to avoid excessive compression due to high seating stress in high-pressure service and it is also used to reduce turbulence in the flange area. It is normally made of the same material as the gasket metallic strip.
