Add a few overlapping supports
Thread Content
How many overlapping supports should be used in a fixed-tube-sheet heat exchanger? Should only the upper fixing support be moved to the lower heat exchanger, or should two fixing supports be added at corresponding positions on the lower heat exchanger?
Add two supports below the lower heat exchanger, corresponding to the two supports below the upper heat exchanger
Thank you for your reply. Is this the case for all fixed-plate heat exchangers, or is it handled on a case-by-case basis? Is there any evidence?
If the temperature difference across the shell sides of the upper and lower heat exchangers is large, and considering the different amounts of expansion of the shells, the upper heat exchanger requires two sliding supports, while the lower heat exchanger still needs one F-support and one S-support.
That’s exactly what our company has always done

Thank you all for your answers. I am currently working with a heat exchanger that features two small-diameter tubes fixed to a tube sheet via expansion joints; the supports for the lower part of this heat exchanger in relation to the ground are of the S,F type. But what types are the four supports used to fix the upper heat exchanger and the lower heat exchanger respectively? What about S,F;S,F or F,F;S,F?
