I am constantly running into problems with designing for external piping loads on small to medium sized thin walled tanks (30-40' diameter by 1/4" plate). They never meet the R/t requirements for API Apex P nor WRC 537. Is there a good solution to this problem? We typically do FEA which is not a...
Thanks for you responses!
Very true about the money, which is why we are trying to figure this out since it does not make since to us.
Do you know why Appendix V uses 1.0 instead of .6?
It just doesn't seem logical for it to not need an intermidate wind girder for wind in section 5 but does...
Vacume = .0625psi. Yeah we have reduced the FOS but it still does not pass due to "W" alone. We reduced by taking the tsmin equation and multipliing it by 2/3.
Do you know why they calculate a different wind pressure in appendix V that is greater than than the wind pressure calculated fore...
Has anyone else had problems with unstiffened shell section of appendix V? We have a tank that passes due to wind with no indermediate stiffeners but when appendix V is applied it no longer passes for just the wind "W". Also the thicker the top shell course gets the more HTS becomes which...
