Tubesheet Thicknesses and Tube Loads for Floatinghead and Fixed-Tubesheet Heat Exchangers

This paper presents procedures for computing tubesheet thicknesses and tube loads for floatinghead and fixed-tubesheet heat exchangers. It was prepared in connection with the activities of the Special Working Group on Heat Transfer Equipment of the ASME Boiler and Pressure Vessel Code Committee, for their use and consideration in the drafting of code rules for these items. The mathematical procedures are closely associated with the publications of Mr. K. A. Gardner. These are references [1 and 2] of the attached bibliography. As far as practicable, the symbols in this paper are those used by Gardner. Some differing symbols are used to be consistent with currently used Code symbols.
