As one of the major activities of the JSME research committee for the improvement of pipe wall thinning management, latest knowledge concerning pipe wall thinning phenomena and state of the art inspection technologies of wall thickness have been surveyed and reviewed. Although a complete management of pipe wall wastage consists of prediction, inspection, and evaluation, survey of the evaluation part has been running late compared to the prediction and inspection parts. Survey of “Risk Based Maintenance” and “Acceptance Criteria for Localized Metal Loss” was recently initiated in the research committee. This paper summarizes scope and status of the survey.
