Abstract
The first edition of the JSME rules on pipe wall thinning management for thermal power generation facilities (JSME S TB1-2006) was issued in March 2006, and its latest edition was issued in September 2007, which describes the technical requirements to meet the JSME performance-based rules for pipe wall thinning management (JSME S CA-1 2005). The latest JSME rules describe the specific requirements for the inspection of piping system that are susceptible to the wall thinning damage based on the analyses of 24,774 inspection data obtained at the thermal power plant in Japan.
