Questions regarding the calculation of tower equipment with heat exchangers
Thread Content
I am currently dealing with a tower unit that contains one heat exchanger. The connection structure between the tube sheet of this heat exchanger and the tower wall is required to follow the design shown in Figure 2. When calculating the tube sheet for this structure, is it necessary to take into account the bending moment at the tube sheet? If it needs to be taken into account, then how should the bending moment be incorporated into the tube sheet calculations?
The optic tract is considered a concentrated load, with the centroid of the tract being the point of action!
It seems that conventional methods cannot be used to calculate the tube sheet; for tower calculations, the method from Floor 3 can be applied.
When calculating the tube sheet for this equipment, the tower moment at the tube sheet section is converted into an equivalent pressure for the calculations. I’m not sure if this approach will work
Can’t it be calculated directly as a heat exchanger tube sheet?
It is a approach similar to the calculation of equipment flanges on towers, but factors such as gravity, wind load, and earthquakes must be taken into account.

It can be calculated by considering this area as the critical section. However, I think it is best for the tube sheet to adopt a butt-welded structure with the cylinder, as the stress conditions in that area are complex, and the welded structure shown in the diagram is not conducive to flaw detection.
