What method is used to design the bottom supports in stacked shell and tube heat exchanger sets? Specifically, the supports on the bottom shell seen here:

I'm well aware of the L.P. Zick and ASME Section VIII Division 2 support analyses - neither of these cover this situation.

  • Please add some information as to why this is more unique than usual? Not everyone may be a pressure vessel designer, but other engineers may have some helpful ideas if you put more detail into what problems you are having. – hazzey Dec 14 '16 at 2:43
  • What information are you looking for? If you're familiar with pressure vessel engineering you'd likely be familiar with the two analyses I pointed out in the OP. The two methods cited are applicable for saddles like the top vessel. The bottom vessel needs to account for loads from the top vessel, the ring around the entire circumference of the shell, and its own combined loadings (wind, seismic, piping, etc.). – user2785724 Dec 14 '16 at 14:19
