    How to apply Appendix S on Appendix 2 Flanges

    Yes you are right. I must have approached it wrongly because Am is, actually, the larger of Wm1/Sb or Wm2/Sa; of course it would suggested that required bolt area will be smaller than that what have been in case of Sa-Sb's values taken from II Part D. However if W, if worked out employing Sa...

    SA240 S31803 Sm ?

    Yar it is duplex material, actually austenitic-ferretic material, and you can easily find the values you need from SECTIO II PART D. All what you will have to do is to pore through number of pages. see pages 389 or like that and then 500 series pages.

    Calculating Vessel Wall Thickness

    Why dont you consider it...second pipe or hole... and the services considered as the cyclic services. For cyclic services make use of the integrally self reinforced contoured nozzle for its better reinforcement.

    Fatigue analysis for the vessel

    There is a method described in the Div II, wherein there is a graph explaining how to calculate it.I shall tell you day after tomorrow as to how to perform fatigue analysis based on the information in the DIV II, because it is lying on my computer in the office. It is an excel sheet.
