Abstract
Magnetic flux leakage-based operating system is widely used for defect inspection of steel pipes. For the pipes with small, straight, and disjointed characteristics, the inspection apparatus called electromagnetic inspection (EMI) is used to exam the condition of full length of pipes from their outer surface by moving pipes through it. In the conventional EMI, the inspection speed is limited by the requirement of helical scanning. To speed up the inspection process, we proposed and manufactured a novel EMI system in which the longitudinal flaw inspection system consists of an orthogonal magnetizer and four sensor arrays so that it only requires a linear motion of pipe. The magnetic field generated by the magnetizer was studied by finite element methods (FEMs) to find out the optimum design. Meanwhile, a hydraulic mechanical system was constructed to ensure the avoidance of wobble effect during scanning.
