Correction Factors for Effect of Temperature on the Tank Shell
For mild steel tanks with a linear coefficient of expansion of 0.0000062 / ° F, whose capacity tables were calculated at a base tank shell temperature (tb) of 60 ° F. For temperatures outside the range of this table use the formula in API MPMS Chapter 12.1.1.
