ABSTRACT:
A device for detecting defects in the bore of a tubular member. The device includes an inspection head including an electromagnet for magnetizing the internal surface of a tubular member. The device also includes a sensor or sensors to detect magnetic flux leakage indicative of a defect. The magnetic flux sensor output is sent to a control-data acquisition system concurrently with signals as to the axial and circumferential position of the defect, which are obtained by their respective encoders. The control-data acquisition system is capable of processing and displaying the data in analog and digital form.
