Modelling and experimental study on pipeline defect characterisations using a pulsed eddy current measurement

Nondestructive Testing and Evaluation
Pipelines are widely used as the main transportation method in petrochemical and metallurgical industries. However, the special nature of the materials transported in pipelines means they are often subjected to high temperature, high pressure and ...

Local Defect Detection of Ferromagnetic Metal Casing Based on Pulsed Eddy Current Testing

IEEE Transactions on Instrumentation and Measurement, 2022
Remote-field eddy current testing (RFECT)-based methods have been widely used in conductive pipe evaluation. However, the response signals of RFECT are affected both by the casing thicknesses around the driver coil and in the vicinity of the pickup coil,

Transient Eddy Current Analysis of Pulsed Eddy Current Testing by Finite Element Method

IEEE Transactions on Magnetics, 2004
Transient eddy current analysis of pulsed eddy current testing was performed by time-stepping method and Fourier transform method. The characteristics of two methods were evaluated by using a simple model. The accuracy was examined by the comparison of calculated and measured data.

The Pulsed Eddy Current Testing

2016
As one kind of eddy current testing technology, the pulsed eddy current testing technology is based on the principle of electromagnetic induction and is used to detect the defects in conductive materials. The principle of pulsed eddy current testing is basically the same as that of traditional eddy current testing, and differences are the means of ...

Pulsed Eddy Current Method: an Overview

1999
As the name implies, the pulsed eddy current (PEC) method uses a transient excitation of an eddy current probe, as opposed to the continuous-wave (CW) excitation used in conventional eddy current inspection. The PEC approach offers several advantages over the conventional method.
