ASME Heat exchanger with tubesheet cutout, a asymmetrical tube layout, rectangular tubesheet
(OP)
Any advice on the following would be greatly appreciated. I've been tasked with doing the ASME Section VIII code calculations for a heat exchanger. However I think it is out of the scope of part UHX for the following reasons: It has a segment of a circle (moon) shaped cutout in the tubesheet, an asymmetrical tube layout and while the shell is cylindrical, the outer shape of the tubesheet is a rectangle. The attached picture should help explain. Can I use part UHX? If not, is there another resource? FEA the only option? thanks!

Your best bet short of FEA might be a UG-34 calculation perhaps incorporating a ligament efficiency. You could perhaps treat the plate as round. The cutout will not be adequately addressed by this approach of course.
I think you are stuck :)

The problem with sloppy work is that the supply FAR EXCEEDS the demand

All I could suggest is full area replacement on the opening.
