In recent years, the importance of utilizing a prediction model or code for the management of pipe wall thinning has been recognized. In Japan Society of Mechanical Engineers (JSME), a working group on prediction methods has been set up within a research committee for studying the management of pipe wall-thinning. Some prediction models for pipe wall thinning were reviewed by benchmark analyses in terms of their prediction characteristics and the specifications required for their use in the management of pipe wall thinning in power generation facilities. This paper introduces the prediction models selected from the existing flow-accelerated corrosion and/or liquid droplet impingement erosion models. The experimental results and example of the results of wall thickness measurement used as benchmark data are also mentioned.
