Mike, thank you
Not clear your answer (maybe also my question was not so clear), anyway seems that you suggest to use my option 1 which as said is not sufficiently "safe": as said it could be that under test some course could be less stressed than in operating/design condition.
P.S. it is not...
Dear ALL,
considering a case where a vertical vessel have different operating pressure at different levels (gas pressure constant along the height plus a material pressure variable along the height - material is having a higher density respect to water).
We define therefore for this vessel...
Dear All,
I've read many interesting post about ASME B16.9 ellipsoidal ratio and calculations rules.
See some of them here below.
thread794-162782
thread794-358427
thread794-355156
None of these seems to address the issue of how to calculate the MDMT for this item.
It is to be considered that...
Sorry was my mistake:
I didn't take in consideration tickness reduction due to corrosion.
Actually by formula I calculated:
hoop component of stress being about 21.9e3psi and the meridional one 10.9e3psi

Dear All, kindly help me to solve this question.
In ASME PTB-3-2010 (ASME VIII Div.2 Example Problem Manual) page 5-11 Table E5.2.1-1 you find Pm=19028psi for the ninth classification line (cylindrical vessel shell far from discontinuities); in the 2013 edition there is the same value; by...
Dear All,
I have the following general question about origin of allowable stresses in ASME VIII div 2.
Are these allowables directly depending and associated with the collapse theory adopted in the formulation or depend more on testing and experience on vessels fabricated with the restricted...
Dear All,
I have some few questions about linearization and stress classification according ASME VIII Div 2 (2013)- Part 5 - Protection against plastic collapse. I kindly ask your help to solve my doubts.
Premise:
At paragraph 5.2.2.4 of the Code - Step 1 is written that: "... separate load...
