Electromagnetic Acoustic Resonance Electromagnetic Acoustic Transducer Flow Accelerated Corrosion Pipe-wall-thinning Superposition of nth Compression
Electromagnetic acoustic resonance (EMAR) method is used for online evaluation of pipe-wall-thinning. In this study, the thickness of the specimens corroded under various conditions is evaluated by EMAR. The thickness is estimated applying the superposition of n th compression (SNC) method to the signals obtained from EMAR. The error of thickness evaluation is investigated in view of thinning shape and the roughness caused by corrosion. As a result, it is suggested that the shape on the order of mm does not...
