Basis for ASME B16.5 Flange Ratings
Basis for ASME B16.5 Flange Ratings
(OP)
Can anyone shine a light as to how the flange pressure - temp ratings in B16.5 are derived?
Calculations?
Flanges tested to destruction?
Everyone I ask doesnt actually know

Wher these flanges ALREDY AND BEFORHAND, ONCE AND FOR ALL FOR A RANGE OF PRESSURES AND TEMPERATURES, calculateD using ASME VIII div.1, appendix 2 ????/
I OTHER WORDS WHAT IS THE BASIS AND THEORY BEHIND B16.5
Something I now , is that ASME VIII -Appendix 2, is based on LA FORGE (?) ....

This brings up my post from the other forum. Appendix 2 added flange rigidity as a mandatory calulation. We design self energzing (o-ring) flanges and have never had an issue with leakage due to flange distortion. Now, for some reason, ASME is forcing us to increase our flange thickness. What is the reason for this change? We have many flange in stock that are now scrap.
Also, ASME B16.5 flanges are allowed per Section VII even though they fail the Appendix 2 calculations. This is a major contridiction.
