Hi,
I am looking into a t.min calculation of an air cooled header box from ’64. It is a bended frame with welded side plates and a bolted cover plate. But I have a hard time figuring out how to handle it, been back and forth between Appendix 13 and UG-34.
I concluded that the sketches in Figure 13-2(a) is comparable to my left view, and therefor Appendix 13 is only for welded frames (plugsheet + tubesheet + top/bottom plate) and then side plate calculated as UG-34. Therefor I miss the option with a detachable cover plate in App-13.
How would you calculate an open frame header box with cover plate? (bended or welded corners).
