Abstract
Methods for reclaiming or reconditioning used tubulars are disclosed. One method includes performing non-visual, non-destructive inspection of used tubulars at a site of a reconditioning or reclaiming plant prior to the used tubulars being cleaned in preparation for reclaiming or reconditioning, followed by sorting the used tubulars based principally on the inspection. The non-visual, non-destructive inspection may be selected from magnetic flux leakage inspection, ultrasonic inspection, Eddy current inspection, acoustic emission inspection, and combinations thereof.
