API 510 calculation for Minimum Required thickness and Remaining Life (API 510 Exam Question)

Bob Rasooli solves the problem to indicate how to calculate minimum required thickness in API 510 and calculate remaining life and determine if pressure vessel safe for operation. There is metal loss 4 inches away from weld seams, and joint efficiency 1 is used to get extra corrosion allowance. However, even with using joint efficiency 1, the pressure vessel is not safe for operation. This is a typical API 510 pressure vessel inspector exam question.

It is either T-initial or T-actual and not T-nominal in API 510.T-nominal is for API 570.Nice lecture!

Thank you so much👍🏼👍🏼👍🏼

[@knowledgetank7282]

Very Good knowledge

[@josecarloschavezclaure9069]

Why do you emphasize indicating that there is no corrosion in the weld seam, if were corrosion in the weld seam do the equation of mínimum thickness required or the evaluation need to change?

[@pgseries]

For determining Corrosion rate, is it allowed to use nominal thickness as initial or previous thickness ?

[@ericsteen5715]

initial but if no readings(CMLs) are taken it will have to be used as pervious also

Nice

How to take allowable stress value (s).

[@i4i-academy]

It is provided to you in problem. However, that can be found on ASME II Part 4

How can I enroll in the API 570, 510
