Fatigue Calc in Div.1 vessel

Fatigue Calc in Div.1 vessel

(OP)
Hi All

If I was to run the fatigue analysis for the the nozzles vessel that is designed with DIV I code and oscillates continually between two different pressure at certain time interval, how do we run fatigue analysis ? I have not seen anything like this before for a div 1. vessel. please suggest. Thanks

RE: Fatigue Calc in Div.1 vessel

For a Division 1 design, this would fall under the auspices of article U-2(g).

I would recommend using the calculations in Division 2, Part 5, Section 5.5 (2007 and later Editions).

RE: Fatigue Calc in Div.1 vessel

Check the ASME Forum.  I just answered this one.
