ASME Sec. VIII Div. 1; Shell reinforcement justification
(OP)
Hello, I am attempting to justify the use of a reinforcing ring (10mm thick by 100mm length by 1265 OD)around the circumference of a shell (10mm thick by 1500mm length by 1245 OD)in-between the shell and the flange. This is reinforcement at the head ends of the shell. ASME BPVC.VIII.1-2015 1-1 (a)(1) requires 10mm thick shell but production insists on 10mm x 100mm reinforcing ring between flange and shell at ends. Flange is App.2. Thanks in advance for your input!

BTW, second sketch doesn't help any.

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

As to a sketches, I think a simple cross section of the (presumably three) parts involved, only, with perhaps weld details would be much more clear. Maybe something like the attached...

Thanks cbPVme! I completely agree with you (and our AI) regarding the mechanical soundness of the design if Code is followed but I am outranked and the ring must be incorporated so the only design calc. solution we have been able to identify, other than U-2(g) w/ UG-101 proof test, is increasing the the shell thickness and removing the ring...
I really appreciate everyone's input! I look forward to participating in the forum in the future! ... and will include better sketches next time :)
