Application range of ultrasonic testing method and magnetic flux leakage detecting method
2019-01-02
Since the transmission of ultrasonic waves must rely on a liquid medium and is easily absorbed by the wax, the ultrasonic detector is not suitable for detection in a gas line and a highly waxy oil line, and has certain limitations.
At present, magnetic leak detection technology is widely used in the detection of long-distance pipelines, oilfield gathering pipeline networks, refinery pipe networks, urban pipe networks and submarine pipelines.
