| Abstract: | The resolution of the flux leakage signals of defect in pipe are studied theoretically.The flux leakage fields inside pipe are measured precisely by the compute-controlled measurement system.Three magnet systems, which magnetize the small-diameter and thick walled subsea pipe,are designed and tested.The desirable magnet system is used to make the smart pig.The ability of the MFL pig to characterize the depth,shape and length of varied defects is evaluated by detecting different aritifical defects. |

| Keywords: | flux leakage fields defect inspection small-diameter and thick walled subsea pipe |
