摘要： A method for measuring a wall thickness of two concentric pipes includes launching a pipe inspection gauge (pig) within an inner pipe of the two concentric pipes; emitting, using an electromagnetic (EM) transmitter of the pig, magnetic fluxes toward one or more EM receivers of the pig; focusing, using one or more focusing devices, the emitted magnetic fluxes to compress and guide the emitted magnetic fluxes through the inner pipe toward the outer pipe and increase a signal to noise ratio of the one or more EM receivers; measuring, using the one or more EM receivers, the compressed and guided magnetic fluxes to generate a measured flux for providing to a pipe anomaly analyzer; and determining, using the pipe anomaly analyzer and based on the measured flux, the wall thickness of an outer pipe of the two concentric pipes.
