Optimization of Tubesheet Thickness of Triple Concentric Pipe Heat Exchanger using ASME codes

Abstract

Heat exchanger is the device used to transfer the heat from hot fluid to cold fluid efficiently. It is made up of various parts and every part has issues regarding its safety. This paper is regarding the tubesheet safety. In this paper, thickness of the tubesheet is optimized for different pressure and thermal loading conditions. Due to the high pressure and high temperature of fluid, tubesheet expands because of which the shell of heat exchanger also expands which generates high stresses and deformations in heat exchanger. To avoid this, analysis of effects of pressure and temperature on tubesheet is necessary. This paper has the objective of analyzing the temperature and stress variation in tubesheet and optimizing its thickness.
