Emat Pipe Corrosion DetectionEmat Pipe Corrosion Detection MB Inspection now offers non-contact emat scans for corrosion detection. The system is designed for rapid assessment of corrosion in piping, including normally inaccessible areas under pipe supports. Electromagnetic Acoustic Transducers induce ultrasonic waves in metals without the need for an acoustic coupling medium. The MBI system is designed for detection and grading of corrosion in piping and under pipe supports in particular. Although emat probes sit on the pipe surface, they are “dry coupled” and relatively unaffected by coatings and light surface rusting. The system operates by transmitting Lamb waves around the pipe circumference. The probes are held in a fixed orientation and carried along the pipe by a motor driven scanner with an encoder to track its position. Ultrasonic (thickness) data is recorded and displayed by a computer for evaluation on the spot and off-line review. Capabilities
