Section III of the ASME Code provides rules in Subsection NB-3600 which greatly simplify the structural evaluation of piping. The key to this simplification is in the use of stress analysis formulas based upon stress indices. These formulas are applicable in the evaluation of compliance with limits on elastically calculated quantities. At present, Code Case N-47 permits, but does not specify, the use of analyses based upon piping stress indices. This paper describes a set of formulas for piping analysis using stress indices. Specifically, stress intensities needed for evaluation of compliance with Code Case N-47 limits on elastically calculated are given using piping stress indices. The specified formulas are examined by comparison with related ANSI B31.1 rules and test data.
