Electromagnetic acoustic resonance method Electromagnetic acoustic transducer thickness measurement，Flow Accelerated Corrosion，pipe wall thinning
Electromagnetic acoustic resonance (EMAR) method is useful for measuring thickness of pipe. But in the case of thickness changing complicatedly in part of pipe wall thinning for various factor, accurate thickness measurement is difficult. In this study, thickness of specimens of pipe corroded under various conditions is evaluated by EMAR. The error of thickness evaluation is investigated in view of maximum value of spectrum and roughness and curvature of pipe. As a result, it is suggested that signal streng...
