The thickness of a plate is to be evaluated from the top surface of the plate.To simulate the small area wall-thinning on the inner surface of a pipe, five AISI316 austenitic stainless steel flat plates with a slot defect were prepared in our ex periments. The size of the five plates is the same, 120mm in length, 100mm i...

Defects Sizing Using a Pulsed Eddy Current Testing Method forLocal Wall-Thinning Evaluation

Abstract: In nuclear power plants (NPPs), due to flow accelerated corrosion (FAC) and liquid droplet impingement (LDI) of the coolant inside the pipe, there may happen local wall thinning defects on the inner surface of a pipe. Concerning the material of pipes, there are mainly two types, low-carbon steel and stainless steel. In this paper, the feas ibility of quantitative nondestructive evaluation (QNDE) to wall thinning in stainless steel pipes using pulsed eddy current testing (PECT) method is discussed...
