API 650 , Section 5 , shell design
(OP)
Good morning
I can't understand how can i use corroded plate thickness in the calculation of the maximum allowable product design stress refering to the tables 5.2a and 5.2b.
Thank's in advance.

RE: API 650 , Section 5 , shell design
Allowable stress is not ( usually ) calculated based on a material thickness, rather it is determined from the material properties modified by the design conditions ( temperature, risk, etc ).
I fear that by your questions, you may not be accustomed to using API 650 and given the risk to public safety if it fails due to a flawed design, you should consult an expert who is familiar with the code. Or at least have your design checked by one skilled in the art of such tank design.
