API RP 5UE (R2020) – Recommended Practice for Ultrasonic Evaluation of Pipe Imperfections, Second Edition, Includes Addendum 1 (2009)

Please note that any addenda or errata may not be included in translated editions of this standard.

This recommended practice describes procedures which may be used to “prove-up” the depth or size of imperfections.

Included in this practice are the recommended procedures for ultrasonic prove-up inspection of new pipe using the Amplitude Comparison Technique and the Amplitude-Distance Differential Technique for evaluation of 1) surface breaking imperfections in the body of pipe and 2) surface breaking and subsurface imperfections in the weld area of electric resistance, electric induction or laser welded pipe and 3) surface breaking and subsurface imperfections in the weld area of arc welded pipe.
