Is it possible, according to ASME UHX, to have a channel diameter different from the shell diameter? It seems that all figures are with the same diameter, but I saw no restriction about it so far.
Thanks for the reply.
So there is no limitation in the diameters? One can be 2/3 of the other? And how (where) the UHW handles the torque generated by the non-alignment of the diameters?

Franck L, I don't see any limitations noted. By "torque" I assume you mean bending imposed on the tubesheet.
I don't have a detailed understanding of Part UHX, but I see definitions of and the use of the various diameters in various calculated terms, leading to calculations of shear and bending stress in the tubesheet. I see the calculations performed for the various loading conditions. I see that the worst case governs.
So, I'd say that the effects of the non-alignment of diameters is handled by complicated and voluminous calculations.

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