While we design & install metallic expansion joints within the piping & equipment, does the component OD change upon contraction & expansion - the axial movement?

Yes there are changes in component /bellow OD and they are considered especially when:
Bellows are installed inside sleeves or guides.
There is insulation clearance.
Bellows are inside pressure vessel annular spaces.
External covers or shrouds are very close to the convolutions.

And that happens in all the cases, irish no matter what kind of design it is?
