Description / Abstract:


The ASME B31 Code for Pressure Piping and the ASME Boiler and Pressure Vessel Code, Section III, Nuclear Components, Subsections NC and ND piping rules require the use of stress intensification factors (i-factors or SIFs) when checking the adequacy of components and joints (welded and nonwelded) in piping subject to loadings, including those cyclic loadings that may produce fatigue failures. As used herein, where the word "Code" is used without specific identification, it means the Code or Standard which incorporates or references this Standard. The piping Codes provide stress intensification factors for the most common piping components and joints. This Standard presents an experimental method to determine SIFs.
