GB/T 42662-2023 Non-destructive testing of steel tubes—Automated ultrasonic testing for the detection of laminar imperfections in strip/plate used for the manufacture of welded steel tubes
Abstract
This document specifies the requirements for the automatic ultrasonic detection of layered defects in steel strips/steel plates used for welded steel pipes before or during the pipe manufacturing process.
Note 1: For welded steel pipes, the manufacturer may choose to conduct automatic ultrasonic detection of layered defects in the steel pipes according to ISO 10893-8 after welding as an alternative method.
Note 2: By agreement between the manufacturer and the purchaser, this document is also applicable to the detection of steel strips/steel plates after welding of submerged arc welded steel pipes.
This document is also applicable to the detection of steel strips/steel plates used for the manufacture of circular hollow steel profiles.
