Issue with tube box thickness input in heat exchanger calculations in SW6-98

Thread Content

When using SW6-98 to perform calculations for fixed-tube-sheet heat exchangers, one of the output results related to the tube sheet is \"Nominal thickness of the shell cylinder (for high-neck flanges, the average of the sizes of the flange neck ends) δh\". I would appreciate it if an expert could explain why it is necessary to use the average of the flange neck end sizes instead of simply entering the nominal thickness of the shell

This is also specified in GB151; I think it is mainly taken into account with regard to the stress conditions on the flanges.
