Dear friends,
I have three questions regarding flange checks in CAESAR II.
1- In flange leakage checks, what types of flanges does pressure equivalent method applicable for? Is it applicable for RTJ flanges or connection of adaptor/backing ring?
2- I have seen many "Stress Analysis Specification" in several projects, but none of them refers to NC-3658.3 for flange leakage check. What is the reason?
3- Is it mandatory to consider compressive force in flange leakage calculations? Why?

Regards,
