Relationship between tube sheet thickness and heat exchange tube length in shell-and-tube heat exchangers
Thread Content
Why does the tube sheet become thicker when the length of the heat exchanger decreases?
Short tubes impose greater constraints than long tubes; sometimes the shell thickness needs to be increased, and the tube sheet also has to be made thicker!

It is mainly a problem related to axial stiffness: the pipes are short, resulting in high stiffness; thus, significant axial thermal stresses occur in the pipes and the housing, which causes the tube sheet to undergo considerable bending deformation. Therefore...
