Yes this is one of the concerns... MW Kellogg company in their 2cd book on design was quite specific requiring that trunnions/ staunchions be used on high temperature lines...

John,
If the difference in thermal growths along the pipe, at the pipe and at the
shoe bottom, is appreciable. I suppose the shoe would literally arch away
from the pipe. Is that the high strain?
Sajit
so while where its attached to the pipe it may be at 1100F at the bottom of
the saddle or shoe it may only be @ 300 - 400 F. This differential may
cause extremely high strains to form at the weld line.
