Elastic stress Analysis of Thick-Walled Expansion Joint in a High Pressure & Temperature Heat Exchanger

In this study, elastic stress analysis of a thick-walled expansion joint is performed that is incorporated into the shell of a fixed tube-sheet heat exchanger. Shell-side and tube-side are subjected to different internal pressures. It is assumed that Poisson’s ratio and modulus of elasticity are constant across the thickness. This analysis is carried out by using the finite element method and considering all requirements of TEMA 9th edition [3] and ASME Sec. VIII, Div. 2, Part 5 [1]. The obtained equivalent stress results of this expansion joint are categorized and compared with the limiting values. In this study all limiting values are exhibited in more details
