longitudinal membrane stress in the tubes exceeded in floating head exchanger
longitudinal membrane stress in the tubes exceeded in floating head exchanger
(OP)
Hi all,
I'm doing the design of a floating head exchanger with microprotol.
I have a problem because the software indicate the following warning 'Tubesheet Loading conditions T0 [test condition] : longitudinal membrane stress in the tubes exceeded'.
What can i do in order to solve the problem?????
Thanks,

RE: longitudinal membrane stress in the tubes exceeded in floating head exchanger
The message does not make sense to me. For a pressure only case you would expect circumferential stress to govern, not lonitudinal, where a differential expansion usually is present.
I frankly have never seen this happen. It may be your only choice is to thicken up the tube wall.
