11/14/2023 0 Comments Magnetic flux leakage![]() ![]() Ask a Dexon Technology expert for more details regarding XYZ pipeline mapping. Pinpoint accurate location data is achieved through the combination and analysis of inertial measurement sensor data (gyroscopic x, y and z orientation data), above ground marker (AGM) data, and PIG travel distance and time stamping data collected during the inspection run. Pipelines whether subsea, above ground or underground can be displaced or damaged by numerous natural and man-made forces including ship anchors, landslides, and earthquakes. Guaranteeing accurate detection and identification of corrosion, pitting, erosion, lamination, gouging, cracking, and other metal loss anomalies.ĭexon’s MFL ILI fleet also incorporates XYZ pipeline mapping capabilities providing accurate information on the physical location of the asset in addition to inspection. Anomalies are detected via changes in flux measurements, with the amount of flux leakage determining the precise length, width, and depth of anomalies for identification. Tri axial hall sensors positioned between the magnetic poles then measure flux leakage originating from anomalies. MFL ILI PIGs use powerful magnets to magnetize the pipe wall. All Pipeline Integrity Gauges (PIGs) are subjected to pre inspection verification testing at Dexon’s on site test yard to ensure comprehensive assessment of your asset based on individual client pipeline configurations. ![]() ![]() Dexon’s Magnetic Flux Leakage (MFL) In-Line Inspection (ILI) fleet offers inspection of pipelines with internal diameters of 3” up to 56” with PIG development and customization available for larger diameters. ![]()
