  • Method and apparatus for magnetic response imaging
    Patent number: 8395376
    Abstract: An apparatus and method for identifying, measuring, and monitoring metal loss through corrosion or other deleterious factors in ferromagnetic piping and ferromagnetic objects. Drive coils secured to the object are driven to emit a magnetic field which is transmitted through the object by magnetic domains in the object. Response coils detect the magnetic domains and generate a response signal. The drive and response signals can penetrate insulating materials and non-ferromagnetic metallic coverings of the piping and vessels. The system operates reiteratively over an extended period of time, e.g., months or years, to detect loss of magnetic domains which is an important indicator of corrosion and deterioration of the object.
