Hi All,
I am relative new to Storage tanks. Why does API-650 Para P 3.3 limits local primary membrane stress and local bending stress to 1.1 Sd while allowing a higher limit of 1.5 Sd for membrane stress. Shouldn't it be the other way round. In pressure vessel we usually limit general primary membrane stress to S and local membrane stress to 1.5 S. Am I reading Para P 3.3 incorrectly. Please tell if I am missing something.
