how to apply nozzle load on flange welded on smaller end of eccentric reducer 1

[inammanj123]

I am working on a div-2 horizontal vessel. there is flange, then eccentric cone, then shell. flange is directly welded to smaller end of cone. Piping has given nozzle load, but i am thinking a how the loads can be applied. Following are scenarios:

1- Since flange is welded to cone, we can not use WRC107, OR WRC297. only option is to use FEA. right?
2-Apart from modelling flange and cone assembly on some fea software, i am thinking of applying force and moment on the flange also. I can do this in PVELITE. Its a Conservative approach and flange thickness is also increasing by doing so or first I should confirm this from piping that where should the loads be applied?

TGS4 - Not sure I understood the PCC-1 Appendix O rules required by CC2901, and certainly didn't review them carefully enough to judge if they're easy or hard. I guess you're telling me they're easy. Good to know for the future. In case Appendix O was difficult I threw out some alternate ideas.

Appendix O should be a default for any flanged joint application. Whether it's easy or hard, it needs to be the industry default setting.
