Problem:
What to do to avoid the error in the floating head design
27 Tubesheet loading conditions, longitudinal membrane stress
Solution:
There is failure due to tube axial membrane stress, the tubes would buckle:
Increasing tube thickness (ex. 5.156 mm) helps remove all of the tube membrane stress errors but that might not be a solution from process/thermal design perspective as tube becomes too thick:
Another solution could be to reduce baffle spacing (example - reducing the spacing to 300 mm)
.
Overall it really depends on what approach the designer wants to adopt.
