This method is finding increasing use in the petrochemical industries for providing high-speed inspections of Storage Tank Bottom and Annular Plates. These systems utilize either permanent or electromagnets to provide localized near-magnetic saturation coupled with induction coil or Hall Effect sensor arrays for detecting anomalous flux leakage caused by the presence of corrosion defects.
They are commonly used for inspecting tank floors in the petrochemical industry. Corrosion of the tank floor can lead to the loss of product and cause damage to the environment. Therefore, it is vital that tank floor inspections are carried out in order to prevent the occurrence of such problems.
