In horizontal fixed-tube-sheet heat exchangers, can the expansion joint be directly welded to the tube sheet?

It depends on how your expansion joint is connected to the tube sheet If it’s plug-in type, then considering adding an extended straight edge section is necessary. Generally, it can be connected directly.

I think it’s possible, but such a structure is not good; the expansion joint is thin and designed for accommodating contraction deformations. When welded to the tube sheet, it definitely results in a poor structural design.
