Patent attributes
A method is disclosed that includes measuring an inner diameter (ID) of a tubular at least at a plurality of points along an inner circumference of the tubular, at a predetermined axial distance from an end of the tubular, to yield a first set of measurements. A computer processor is used to: create a tubular profile from the first set of measurements, wherein the tubular profile represents a unique identification code of the tubular; save the profile; and thereafter identify the tubular. The tubular is identified via: receiving a second set of measurements of the ID of the tubular from at least at a plurality of points along an inner circumference of the tubular, at the predetermined axial distance from the end of the tubular; and comparing the second set of measurements with the saved tubular profile to identify the tubular.
