Select the appropriate expansion joint type. If you select an Expansion Joint Type of Thin (Bellows) or Thick (Flanged-flued), the software activates and advances you to the Expansion Joint tab.
The following options are available:
-
None - Select this option when there is no expansion joint in the heat exchanger.
-
Thin Expansion Joint - Select this option if the expansion joint is a bellows type expansion joint. The figure below shows an unreinforced bellows type expansion joint. In this case you should use the Thin Joint module to design the bellows type expansion joints (both reinforced and unreinforced). Then specify the computed spring rate.
-
Thick Expansion Joint - Select this option if the expansion joint is:
-
Flanged-flued
-
Flanged only
-
No flanged or no flue.
-
Select Thick (Flanged-flued) if you want to perform finite element analysis (FEA) on the expansion joint.
