4.3 SHELL-AND-TUBE DESIGN CODES
4.3.6 Design examples: Floating-head and fixed tubesheet exchangers
M.Morris (1992) and D.Harris (1982)
A. Introduction
The mechanical design in this section is for a floating-head shell-and-tube exchanger (TEMA type AJS). For comparison, the fixed tubesheet design of a TEMA type AEL exchanger is carried out in Section 423H. They conform to the Standards of Tubular Exchanger Manufacturers Association (7th ed., 1988) and the ASME Boiler and Pressure Vessel Code (Section VIII, Division 1, 1989). The calculations are in SI units.
