[vc_row][vc_column][vc_column_text]Magnetic Flux Leakage Testing – This method is used on tank floors since 1980; it uses a magnetic bridge to introduce as near a saturation of flux as possible in the test material. Any significant reduction in the thickness of the plate will force some of the flux into the air around the reduction area. Sensors that can detect this flux leakage are placed in between the poles of the magnetic bridge. It is widely applied to above ground storage tanks to provide a reliable indication of the overall condition of the tank’s floor within an economical time frame. It is a qualitative type testing, giving only an indication of the existence of the corrosion, but no indication of the size (depth) of the plate thinning is possible. Usually, when an anomaly is detected by the MFL tool, it is confirmed and sized by ultrasonic thickness measurements.
Map out the condition of your tank bottom with our magnetic flux leakage (MFL) machine. Ours technicians can generate an accurate picture of the bottom of your tank and follow up with ultrasonic testing to verify the thickness of your tank bottom so that you’re better prepared for estimating tank remaining life and planning repairs in relevant locations.[/vc_column_text][/vc_column][/vc_row]
