Magnetic Flux Leakage Detector

Magnetic Flux Leakage

Magnetic Flux Leakage Detector



Specification range: 8”~ 56”

Identification range:

·Metal loss defects such as internal and external wall corrosion, mechanical damage, etc

·Cracks, abnormal defects in welds

·Pipeline characteristics such as circumferential welds, bends, and lengths

·Valves, tees, and other pipeline installations



Magnetic Flux Leakage Detector, equipped with a probe that induces changes in magnetic field, utilizes the principle that the thickness of the pipe wall affects changes in magnetic flux leakage, collects changes in magnetic flux leakage, downloads data after operation, and uses interpretation and analysis software to identify and calculate the data. It can determine the precise position and size of defect information and related pipeline accessories, and achieve the detection of pipeline metal loss.
