Effect of debris-induced lift-off on magnetic flux leakage inspection results
type: CreativeWork
description: Debris is present in all pipelines and has the potential to cause debris-induced lift-off in magnetic flux leakage inspection tools. A test apparatus was developed to qualitatively examine the effect of debris-induced lift-off.;The results of this research indicate that debris-induced lift-off has a detrimental effect on magnetic flux leakage data. This increases the potential of pipeline defects being either undersized or missed.;To reduce or eliminate the effects of debris-induced lift-off, the pipeline should be regularly cleaned. This minimizes the occurrence of large accumulations of debris. If it is determined that debris is present in a pipeline, even in small quantities, the pipeline should be cleaned using the appropriate pipeline cleaning method. This improves the quality of the magnetic flux leakage inspection data and resulting integrity assessment.
