Scope

This document specifies the requirements for automated ultrasonic transverse wave
(generated by conventional or phased array technology) inspection of submerged arc
welded (SAW) steel tube or resistance and induction welded (EW) steel tube welds.
For SAW tube, this inspection includes detection of imperfections primarily parallel to
the weld, or perpendicular to the weld according to agreement, or in both directions.
For EW steel tubes, this inspection includes the detection of imperfections oriented
mainly parallel to the weld. For longitudinal imperfections, Lamb wave detection is
chosen by the manufacturer.
For imperfections in the EW tube welds, full circumferential ultrasonic inspection can
be performed.
This document also applies to the inspection of circular hollow profiles.
NOTE: For full circumferential ultrasonic testing of seamless steel tubes and welded steel tubes
(except SAW steel tubes), see ISO 10893-10.
