The pipe gets a temperature gradient over the wall thickness. The outside fibers will thus restrain the inner fibers from expanding. I would like to know the increase in the inner dia of the pipe.

I have found temperature gradient dependent formulas in

*Roark’s formulas for the stress*in the casing wall but I can’t find any analytical formulas for the diametrical change on the inside (or outside) diameter.
