Unsaturated Magnetic Flux Leakage Detection and Identification of Scratches in Oil and Gas Pipelines

The online detection technology for oil and gas pipelines can effectively detect metal loss defects, but it has limited ability to distinguish corrosion and mechanical damage scratches. Aiming at the shortcomings of existing pipeline detection technologies, a DC yoke unsaturated magnetic flux leakag...
