Local internal corrosion is one of the main factors causing oilfield pipeline failures. For diagnosing the equipment state, non-destructive testing methods are used. For the eddy current testing, which is one of such methods, there is no need to remove the pipe insulation sheath, which greatly simplifies the diagnostic procedure. The article presents a study of various pulsed eddy current probe (ECP) configurations to evaluate their flaw detection potential in regard of detecting local internal corrosion. The choice of the ECP pulsed excitation principle is stemming from a significant eddy current penetration depth owing to a wide range of exciting pulse frequencies and also the possibility to obtain a multiparametric information on the object examined. Finite element models of three ECP versions with a rectangular, semicircular and Pi-shaped magnetic cores were constructed in the environment of electromagnetic field analysis software. It has been found from the finite element simulation results that among the ECP configurations studied, the ECP with a semicircular magnetic core has the highest excitation energy utilization factor along with high sensitivity to bottom defects. The data obtained will form the basis of an eddy current probe prototype, which will be developed for experimental studies on steel samples.
