T/CSTM 00674-2023 Active

Scope: This document specifies the terms and definitions, general requirements, detection methods, detection systems, probes and comparison samples, detection implementation, display and evaluation, acceptance, detection reports, and archiving for the automatic ultrasonic detection of water spray coupling on seamless steel pipes. This document applies to the ultrasonic detection of longitudinal and transverse defects and delamination (or thickness measurement) in seamless steel pipes with an outer diameter not less than 6mm and a wall thickness-to-outer diameter ratio not greater than 0.2. For the inspection of steel pipes with a wall thickness-to-outer diameter ratio greater than 0.2 and less than 0.3, the detection can be carried out in accordance with Appendix A of this document upon agreement between the supplier and the purchaser. For the detection of steel pipes with a wall thickness-to-outer diameter ratio greater than or equal to 0.3, the detection shall be conducted in accordance with the method agreed upon by the supplier and the purchaser.
