Abstract: An expansion joint is normally employed to alleviate the tube axial load in fixed tubesheet heat exchangers. Incorporation of an expansion joint usually results in increased tubesheet thickness and hence increased cost of hardware. A design strategy to simultaneously reduce both tubejoint load and tubesheet stress in the heat exchanger (without the usual recourse of expansion joints) is presented in this paper. The range of application and practical feasibility of this concept is also discussed.
