Abstract

With the introduction of new higher strength steels operating at higher pressure, the need for characterization of hydrogen content in high strength steel pipelines is timely for the pipeline industry. The higher-strength steel pipelines have higher susceptibility to hydrogen damage. Through the use of low-frequency induced current impedance measurements, a new non-contact sensor has been developed for real-time determination of diffusible hydrogen content in coated pipeline steel. A measurement scheme to separate variables associated with pipelines is discussed. This electromagnetic technique allows for a rapid, non-destructive assessment of hydrogen accumulation in coated steel line pipe and thus an evaluation of the pipeline integrity.
