The thickness at the thickest part has taken into account the thinning at the flange connection and the thinning in the split-channel areas during the heat exchanger calculations

I think it is the effective thickness; when calculating strength, we *usually use the nominal thickness.

Our teacher also said to use the effective thickness. Furthermore, can the m value in the design of fixed-tube-sheet heat exchangers be greater than 1?
