Method for improved crack detection and discrimination using circumferential magnetic flux leakage |
摘要 |
A method of predicting at least one physical change in crack geometry based on ILI operating pressure, the method comprising a) performing a first test on a pipeline at a first pressure P1; b) obtaining a first set of test data on the pipeline at P1; c) performing a second test on the pipeline at a second pressure P2; d) obtaining a second set of test data on the pipeline at P2; and e) analyzing the first and second sets of test data for difference in feature signature at P1 vs. P2.
