On basis of analysis about buriedpipeline nondestructive examination technology, the applications of the magnetic flux leakage test and metal magnetic memory test in nondestructive detection were discussed. Based on the respectively characteristic of the two methods, an integrated test mode based on magnetic flux leakage technology and metal magnetic memory technology was introduced for the buried pipeline. According to the detection system special requirements, an intellectual control system was established to deal with the center circuit control process with double core control model as the important system technology. At last, a simulation experiment was designed to verify the nondestructive detection system practicability in actual engineering condition.The results show that the test model can make up for the shortage of magnetic flux leakage technology or metal magnetic memory technology, and acts a vital role in the pipeline flaw nondestructive detection work.
