Annular Plate Requirements in Apx. X
(OP)
Has anyone noticed that the stress thresholds requiring the use of an annular plate in Apx. X.3.2 are the same as when using carbon steel? That seems odd when the duplex allowables are higher.

Thanks for the responce.
I understand the hoop stress issue but my question was dealing with a must higher strength material subjected to the same hoop stress as carbon steel. Would not the threshold for a reaction as you describe be higher for duplex than for carbon steel?
