Thermal Expansion Problems Heat vrs Cold
(OP)
Do you address piping configurations different for
hot applications versus cold.
Let's say you have one end of the spectrum where the
temperature is +500 Deg. F and on the other you have
-500 Deg. F. What do you do differently to prevent
moments from taking place?

No, as far as I know, cold and hot are addressed in the same manner. The temperature difference is all that matters, as long as you stay above the Code-specified minimum metal design temperature which for example, for A106B is -20° F (I think). The temperature difference is used to calculate the thermal reactions on the pump flanges.
Thermal loads may be the least of your worries. Don't forget about deadload, seismic, and pressure thrust...
