In order to detect the corrosion defects in steel pipeline efficiently and conquer the deficiency of ultrasonic test, the detection method based on giant magneto-resistance sensor was adopted. It was introduced firstly on the principle of corrosion defect detection in steel pipeline and the component of detection system based on giant magneto -resistance sensor. The corrosion defects detection was tested. The defects signal was acquired and processed. The characteristic of the defect was shown to us and realize detecting the corrosion defects in steel pipeline efficiently.
