RE: Thermal expansion and displacement
You could start by finding the Ccoefficient of thermal expansion may be in (mm/mm/deg C or similar) for the vessel material and multiply that by the temperature range and the length under consideration.

RE: Thermal expansion and displacement
Steps:
1. Find the material of construction.
2. find/determine the installed temperature in Deg C
3. Find/determine the Design or operating temperature in Deg C
4. Using the material from step 1 determine the Expansion Coefficient in mm/mm/Deg C
5. Determine/find the length of the vessel in mm.
6. Thermal Expansion is then Expansion Coeff (from Step 4) multiplied by the temperature difference (Temp in Step 3 minus Temp in Step 2)multiplied by the length of the vessel from Step 5.
7. To calculate the thermal displacement: Thermal Displacement = Thermal Expansion.
Simples really!!!
Expansion Coefficient should be taken as the mean value between the Temp in Step 2 and the Temp in Step 3. ASME VIII Part D has listed Expansion Coefficients.
