Insulation is often necessary in the oil industry for certain applications. The problem is that if moisture penetrates the insulation, combined with high temperatures, corrosion is generated. Pipe inspection is therefore very important, and conventional techniques such as ultrasonic testing are an option, but they require a major investment because the insulation must be removed for inspection and then reinstalled. There is a much more efficient solution that does not require insulation removal: Pulsed Eddy Current.

Storage tanks are fixed components found in oil plants. They must be inspected with the most efficient equipment because the time invested in tanks is considerable due to their size. There are two critical zones that must be inspected. First, the tank floor, where an MFL system is recommended to locate corroded areas, followed by a detailed ultrasonic inspection of those zones. The second critical area is the tank walls. For this, an ultrasonic system capable of performing scans is recommended, ideally with magnetic wheels to move along the walls and make inspection easier, avoiding the need to build scaffolding around the tanks.
