Non-destructive testing of steel tubes - Part 9: Automated ultrasonic testing for the detection of laminar imperfections in strip/plate used for the manufacture of welded steel tubes (ISO 10893-9:2011)
This part of ISO 10893 specifies requirements for the automated ultrasonic testing of strip/plate used in the manufacture of welded tubes for the detection of laminar imperfections carried out in the pipe mill before or during pipe production.
NOTE 1 For welded tubes, an alternative ultrasonic testing specification for the detection of laminar imperfections is available, which can be applied, at the discretion of the manufacturer, by ultrasonic testing of the tubes subsequent to seam welding according to ISO 10893-8.
NOTE 2 By agreement between the purchaser and manufacturer, the requirements of this part of ISO 10893 can be applied on strips/plates of SAW tubes in the pipe form after seam welding.
This part of ISO 10893 can also be applicable to the testing of strips/plates used in the manufacture of circular hollow sections.
