Pipe wall thinning is an important issue for aging management of nuclear and fossil power plants. The Japanese Society of Mechanical Engineers (JSME) published a guideline on pipe wall thinning management in 2005 and since then, thinning of pipe wall thickness has been managed based on non-destructive inspection of pipe wall thickness. In JSME, research committee for the improvement of pipe wall thinning management has been established since 2008. In this committee, surveillance studies have been conducted on concerned technical area including wall thinning prediction and inspection method to revise a technical knowledge report attached to the JSME guideline. This paper summarizes recent advances of technical knowledge regarding flow accelerated corrosion and liquid drop impingement.
