Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 18256-2000 "welded (except submerged arc welded) for verification of hydraulic compacting Ultrasonic testing party Law, "compared with the GB/T 18256-2000 main technical changes as follows. --- Detection products increased by seamless steel pipe; --- It will be seized by the minimum diameter of 16mm pipe revised to 10mm; --- Increased requirements for drilling artificial defects and the size of the corresponding type of injury; --- Increasing the corresponding requirements of Lamb waves and phased array detection. This standard uses the translation method identical with ISO 10332.2010 "Non-destructive testing is used to confirm steel seamless and welded (SAW Except) automatic ultrasonic testing method of hydraulic leak "(in English).
