Advantages of pipeline magnetic flux leakage detection
Magnetic flux leakage detection uses magnetic sensors to detect defects. Compared with penetration and magnetic powder methods, it has the following advantages:
1) Easy to automate. The signal is received by the sensor, and the software determines whether there is a defect, which is suitable for forming an automatic detection system.
2) High reliability. From sensors to computer processing, the errors caused by human factors are reduced, and the detection reliability is high.
3) The initial quantification of defects can be achieved. This quantization can not only realize the existence of defects, but also make a preliminary assessment of the degree of defects.
4) For pipes with a wall thickness of less than 30mm, both inner and outer wall defects can be detected at the same time.
5) Because it is easy to automate, it can obtain high detection efficiency and no pollution.
