Investigation of Stress Indices and Directional Loading of Eccentric Reducers
OAK- B135 Engineering for fatigue is an essential concern in piping systems. Addressing this concern, the ASME Section III and ANSI B31.1 Codes provide stress indices and stress intensification factors (SIFs) to be used in the design and evaluation of Class 1, 2 and 3 systems. In recent research cosponsored by EPRI and the U.S. DOE, new test data have been developed for comparison with the ASME stress indices and SIFs. This report presents the results of fatigue tests on eccentric reducers, taking into account the directionality of the loading. As detailed in the report, the results can help to improve the evaluation of reducers and can help to reduce unnecessary conservatism in piping system design.
