Hi Vermaccio
In the external flange anlysis module, the stress calculation methods are based on ASME VIII Div1 App.2 and the ANSI B16.5 tables.
I would leave the flange class blank and type 0 for the flange grade as the module only has ANSI 16.5 ratings in-built to compare, but we know the pressure rating limits of the PN16 flange to compare the results of the module calculation ourselves.
Thank you
Best Regards
Ryan Martin
