allowable loads at for API650 tank with tank diameter lower than 36m (120ft)
allowable loads at for API650 tank with tank diameter lower than 36m (120ft)
(OP)
Hello to everybody!
API650 Appendix P is applicable in order to estimate expansion and rotation at nozzles and then check allowable loads at nozzles "for tanks larger than 36m in diameter, and only when specified by Purchaser for tanks 36m in diameter and smaller".
I have a question...
How do you proceed if the tank diameter is lower than 36m? What procedure for nozzle loads check do you apply?
Thanks for your cooperation.

Assuming that the 120' limitation was in fact a reflection of that assumption, the key factor would be whether shell thickness for your tank is controlled by calculated thickness or by the minimum thickness. If it's controlled by calculated thickness, I would think you could go ahead and use it.

Other question about this calculation:
If the ration of Nozzle Diameter / Nozzle Thickness is smaller than 20 (WRC 297 Limit), How Can I proceed with calculations?? Only FEA is accepted calculation?
Thank you!

but unfortunately my tank is large to its thickness, the ratio Rm/T is greater than 300. (WRC 107 Limit)
At WRC 537 this value can be greater?
Thank you again.
