Non-destructive testing of steel tubes - Automated full peripheral ultrasonic testing of seamless and welded (except submerged arc-welded) steel tubes for the detection of longitudinal and/or transverse imperfections has-tracked-changes 6 mm < a ≤1 Scope This part of ISO 10893 specifies requirements for automated full peripheral ultrasonic shear wave (generated by conventional or phased array technique) testing of seamless and welded [except submerged arc welded (SAW)] steel tubes, for the detection of longitudinal and or transverse imperfections. Unless otherwise specified in the purchase order, the testing method is applicable to the detection of predominantly longitudinal imperfections. In
