Testing the structural integrity of pipelines is a crucial maintenance task in oil and gas industry. This could be compromised by corrosions that occur pipeline wall. They cause catastrophic accidents are very hard to detect due presence insulation cladding around pipeline. corrosion manifests as reduction pipe wall thickness, which can detected quantified using Pulsed Eddy Current (PEC) state-...

A method that uses induced pulsed eddy currents for characterization of thick magnetron sputtered Nb coatings on steel is presented in this paper. The objectives of this work are to develop a system for rapid quantitative nondestructive inspection of coatings as well as to determine the correlation between coating properties, such as density and purity, and eddy current measured resistivity of ...
