AbstractAbstract
[en] This paper involves an evaluation of the safety factors in the proposed ASME Section XI criterion (IWB 3640) for flaw acceptance in austenitic piping. In developing the end-of-life flaw sizes in IWB 3640 several simplifying assumptions were made in using the net-section collapse criterion. Safety factors on stress were used in developing the IWB 3640 end-of-life flaw sizes. This paper examines not only the safety factors on stress, but also the safety factors on flaw depth of the IWB 3640 values relative to a detailed net-section collapse analysis. Prior to making these comparisons, a review of the development of the net-section collapse analysis for circumferential cracks is given
