Thanks Dan,

I think, as we are following ASME sec-VIII for the flange leakage check.
This above stated statement also taken from same code, so the developer (COADE) need to take initiative to provide one option in flage leakage module.

Option:
Whether corrosion allowance applicable.
If, yes -----> (X) mm.

Then caesar perform flange leakage check accordingly.

Richard, I think we may update this in new revison.....
