Abstract

In order to reasonably design magnetizer of circumferential magnetic flux leakage inspection in pipeline, the magnetizer structure that has the circular geometry of quadrupole separation is proposed which meets engineering design requirements with the analysison and comparison of the finite element simulation. After the application of magnetic circuit theory, the influence of the geometric size of permanent magnets on MFL signal is determined. The results help to hold the design of magnetizer for improving inspection sensitivity and meeting engineering design requirement.
