MFE Tank Floor Assessment

Benefits

Rapid inspection of large areas.

Locates surface pits both topside and bottomside.

Highly portable for restricted access tanks.

Inspects through thin coatings.

PetroChem Inspection Services provides complete inspection of tank floor bottoms for both topside and bottom side erosion/corrosion. For larger carbon steel storage tanks (above 20' diameter) it is usually cost effective and advantageous to employ a magnetic flux examination tool to facilitate this inspection. PetroChem Inspection Services has been providing this service to its clients for many years and is in the forefront of the technological changes constantly taking place.

PetroChem currently utilizes the MFE 2412 tool manufactured by MFE Enterprises. The basic principles involved in this tool include the saturation of the floor plate with a magnetic flux and the detection of flux leakage. For this particular application a magnetic bridge is used to introduce as near a saturation of flux as possible in the inspection material between the poles of the bridge. Any significant reduction in the thickness of the plate will result in some of the magnetic flux being forced into the air around the reduction.

Sensors, which can detect this flux leakage, are placed between the poles of the bridge. When leakage fields are detected by the sensors a display alerts the operator to the presence of the leakage field. This area is physically marked up on the tank floor and the remaining wall is verified by ultrasonic means utilizing either B-Scan or A-Scan technology.
