| Abstract: | The methods of defect signal extraction in the oil pipeline magnetic flux leakage detection are introduced.A method of distinguishing the flaw type according to the matching degree of the flaw signal with the known type flaw templates is studied.The establishment method of the flaw template and the criterion of flaw type discrimination are described.The results of simulation experiment show that the discrimination method can effectively identify the types of defects. |
