Regardless of the calculation method, you will need to get properties from the flange manufacturer to analyze, and thus should be the place I'd recommend starting. Attached you'll find a lecture from Dynaflow on the subject, also found here.
thank you. A question about equivalent pressure for a GRP pipe and GRP flange. Can i calculate it by "flange check" flag inside caesar? i use iso14692.
