Abstract
A method for inspection of tubular goods includes using ultrasonic detection means to obtain wall thickness measurement of discrete sections of a tubular good and recording each measurement in association with both the longitudinal and circumferential position at which each measurement was obtained. Accordingly each measurement of wall thickness represents a small portion of the wall thickness of said tubular in three dimensional space. A plurality of said measurements may thereby be displayed by computer means in virtual three dimensional formal. Differing wall thickness readings made he represented by different shading or color display, so that anomalies of interest may be readily detected. Alternatively the recorded information may be readily processed by computer means to calculate the effect of stressors on the wall of said tubular good.
