METHOD, DEVICE AND APPARATUS FOR DETECTING PIPELINE DEFECT |
摘要 |
Provided are a method, device and apparatus for detecting a pipeline defect. A method for detecting a pipeline defect can accurately detect a position and a extent of the pipeline defect, and specifically comprises: detecting, along a length direction of a pipeline, a first parameter related to a magnetic flux density; determining whether the first parameter exceeds a preset threshold; determining a position where the first parameter exceeds the preset threshold as a position of the pipeline defect; and determining a extent of the pipeline defect on the basis of a value of the first parameter exceeding the preset threshold. |
