Orifice Flanges

[Leo165]

ASME B-16.20 deals with metallic/Semi metallic gaskets for ASME B-16.5 and B-16.47 (Pipe Flanges).
What about gaskets for Orifice flanges, Which standard is used ?
B-16.20 can be used ?

The Gasket you should use for an Orifice Flange set is the same Gasket you would use for a Gate Valve in the same service.

Sometimes its possible to do all the right things and still get bad results

Yes agreed with Pennpiper. Selection of the gasket is related to piping, not the orifice. If you are sizing an orifice flow meter, please follow your site piping standard for gasket selection.
