Abstract

This Standard specifies requirements for the automated angle beam ultrasonic examination (including the method using phased array probe) of longitudinal imperfections of seamless steel tubes and longitudinal imperfections of welded portions of welded steel tubes (excluding submerged arc-welded tubes). <br>However, if specified by the product standard or agreed between the purchaser and the manufacturer, the method may be also used for inspection of transverse imperfections on seamless tubes, and longitudinal imperfections of tube body of welded steel tubes. <br>This Standard is applicable to steel tubes with an outside diameter equal to or greater than 10 mm, and normally with a thickness-to-outside diameter ratio equal to or smaller than 20 % ¹⁾. <br>Note ¹⁾ The method applicable to inspection of longitudinal imperfections of steel tubes with a thickness-to-outside diameter ratio greater than 20 % is shown in Annex A. <br>NOTE 1 <strong>ISO 10332, ISO 10893-10</strong> and <strong>ISO 10893-11</strong> permit the use of the Lamb wave technique for inspection of longitudinal imperfections. <br>NOTE 2 The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows: <br>ISO 10332: 2010 <em>Non-destructive testing of steel tubes-Automated ultrasonic testing of seamless and welded (except submerged arc-welded) steel tubes for verification of hydraulic leak-tightness</em> <br>ISO 10893-10: 2011 <em>Non-destructive testing of steel tubes-Part 10: Automated full peripheral ultrasonic testing of seamless and welded (except submerged arc-welded) steel tubes for the detection of longitudinal and / or transverse imperfections</em> <br>ISO 10893-11: 2011 <em>Non-destructive testing of steel tubes-Part 11: Automated ultrasonic testing of the weld seam of welded steel tubes for the detection of longitudinal and / or transverse imperfections</em> (Overall evaluation: MOD) <br>The symbols which denote the degree of correspondence in the contents between the relevant International Standards and <strong>JIS</strong> are IDT (identical), MOD (modified), and NEQ (not equivalent) according to <strong>ISO/ lEC Guide 21-1</strong>.
