Bottom Plate Magnetic Flux Leakage (MFL) 

When conducting out of service inspections, the best and most complete way to evaluate bottom plate integrity is to perform a Magnetic Flux Leakage floor scan (MFL). The MFL equipment creates a magnetic flux that saturates the floor plate. Completing this inspection technique gives the operator and the client the best information for detecting underside corrosion. The operator conducts this inspection by pushing the scanner at a walking pace while marking areas of change to the leakage field that can indicate material loss of the floor.

Ultrasonic Inspection to Areas of Concern

After marking out areas of concern, the target location will have Ultrasonic inspection performed. This inspection will provide the remaining wall thickness and our inspectors will give our client the remaining life of the floor.

Magnetic Particle Inspection of Welds

Magnetic Particle Inspection, or MT, is used to check for cracks and discontinuities in the shell to bottom weld, nozzles and appurtenances. 

​

Radiographic Testing of Welds

Radiographic testing, or RT, uses a radioactive source to inspect the welds on tanks and vessels. Radiographic testing may reveal discontinuities such as lack of fusion, or inclusions trapped during the welding process.
