SIGMA NDT provides tank floor scanning services using the Low Frequency Elctromagnetic Technique “Falcon Mark II” system. SIGMA NDT can also inspect the welds using the Hawk eye System.
The Low Frequency Electromagnetic Technique (LFET) does not use permanent magnets as is common in Magnetic Flux Leakage (MFL) equipment. The Falcon Mark II can scan through coatings and tightly bonded scale. The system is lightweight, battery operated, and portable. The Falcon Mark II is used to scan the floor plates for topside and underside corrosion. Areas identified with the scanner are then marked and verified with ultrasonics.
