Abstract

There are many abnormal points in the magnetic flux leakage internal inspection results of a crude oil pipeline. For 20 of the more serious metal loss anomalies Internal corrosion evaluation standard specification, corrosion evaluation and pressure analysis. The results of corrosion evaluation and pressure analysis are taken as the basis for theoretical screening, and the final selection is preferred. The excavation verification and defect repair were carried out at 3 abnormal points of internal inspection. The accuracy of magnetic flux leakage internal detection results is verified through excavation verification, which proves the magnetic flux leakage internal detection. The measurement technology can play a role in the evaluation and analysis of pipeline corrosion.
