Abstract
This paper aims at a quantitative nondestructive evaluation of pipe wall thinning using an electromagnetic acoustic transducer. Type 304 stainless steels sample specimens that are fabricated by a semi ellipse were provided for our experiments. First, results of measurement and simulation experiments are shown using the provided test samples. The variety of simulation results showed good agreement with laboratory experimental results. Second, the sensitivity of pulse echo signals with respect to corrosion geometry of pipe wall is investigated. Finally, the feasibility studies of our sizing methodology are summarized for evaluating FAC and early LDI test samples.
