Stress indices and stress intensification factors are used in the design of piping systems that must meet the requirements of ASME Section III for Class 1 and Class 2 systems. This study reviews the present values for eccentric reducers and provides new test data for comparison, which takes into account the directionality of the loading. Suggestions are presented which significantly improve the evaluation of reducers.
