Pulsed Eddy Current (PEC) has been successfully deployed over the last decades for a variety of corrosion-related applications, most notably for Corrosion Under Insulation (CUI) inspections, Corrosion Under Fireproofing (CUF) and Flow Accelerated Corrosion (FAC), inspection of corrosion scabs, etc. This technology has proven to be an efficient screening tool, allowing for detection of corrosion without having to remove coating or insulating material over typical pipes and tanks. PEC has been successfully used for inspection of critical structures in the petrochemical, chemical and nuclear industries and in conventional, off shore and underwater environments.
This paper presents the most recent developments made in pulsed eddy current testing technology. The performance of latest improvements of PEC technique is compared to prior art technology, and benefits are discussed. Key applications are presented, with examples of success stories and more complex inspections. Best practices, potential culprits, main advantages and limitations of PEC are discussed for each application.
