APPLICATION OF TRANSIENT ELECTROMAGNETIC METHOD IN MUNICIPAL BURIED GAS PIPELINE DETECTION

摘要

The safe operation of gas pipeline is related to the liveihood of people, in the process of operation, many factors will cause pipeline failure, leakage and accidents and thus impair people's well-being and property safety. This paper puts forward the transient electromagnetic method for in-service detection of municipal buried gas pipeline, mainly introduces the principle of transient electromagnetic method and the factor analysis of pipeline failure, and comprehensively analyzes the problems existing in the application of transient electromagnetic method in in-service detection of municipal buried gas pipeline combined with two examples of gas pipeline detection. The result shows that transient electromagnetic method is practical in the detection of municipal buried gas pipeline, which can better distinguish corrosion thinning and interference, and provide reliable theoretical data basis for in-service safe operation detection and maintenance of municipal buried gas pipeline.
