This paper presents the results from a series of fragility tests to assess the capacity of integral welded pipe attachments of various configurations. Both limit load and fatigue tests were performed on rectangular lugs and crosses (cruciforms) on straight pipe. The results of the limit load tests are presented as a limit moment. The results of the fatigue tests are cycles-to-failure. Markl`s equation is then used to determine stress intensification factors. The limit moments and stress intensification factors are then compared to those developed using the methodology of ASME Code Case N-318 to determine the level of conservatism in the Code Case.
