Xionggu Magnetic flux testing is applicable to the magnetic flux leakage internal detection of the pipeline with the diameter of 323.9mm-325mm, realizing the detection of the buried pipeline under the trenchless condition, with fast detection speed, high efficiency, three-axis ultra-high definition, artificial intelligence data analysis and automatic evaluation. It can effectively detect the defects of buried pipelines, pipe wall changes, internal and external defects, pipe hoop, pipe scar, elbow, weld, tee and other features, provide the area, degree, direction, location and other information of defects and features, and is widely used in the detection of crude oil, product oil, natural gas and other pipelines.
