Abstract |
The present work aims to evaluate theoretically the axial, bending and equivalent stress of tube sheet, shell and tube stress, according to size, thickness and dimension of shell and tube heat exchangers. In addition, effects of stress due to variations of tube side and shell side temperature are investigated. Our ultimate purpose is to ensure safety of design products and develop new products rapidly. According to our results, first of all, the effective pressure, and stress of tube sheet and shell increase with an increment of the shell diameter and a decrement of tube temperature under constant shell temperature. Next, these decrease with an increment of the number of tube, shell thickness and shell temperature under constant tube temperature. Finally, the stress of tube row decrease when the equivalent stress of tube increases. Stress knowledge related to various parameters will be helpful for designers and manufacturers. |
