ASME BP&V Div 2 2007 - Corrosion Allowance

[JoeyMoJo]

Performing a FEA analysis under ASME BP&V Code Div 2 2007 version under Part 5 - Design by Analysis Requirements.

When analyzing the primary plus secondary case (PL+Pb+Q = Sps) do you use the corroded or non corroded version of the vessel? Also where in the code or other reference does it state this so I can reference it for my calc.


What about for fatigue?


Thanks

What does the UDS say?

If the UDS is silent, then I would preform the analysis in the configuration that gives the highest stress range.

There is no guidance in the Code itself - this is something that the UDS should address.
