T/CSTM 00422-2022 Nondamage detection B-scan ultrasonic guided wave detection method using low- to medium-frequency magnetic-induced flexural wave
Basic Information
Scope
Scope: This document specifies the method of imaging detection for defects with changing cross-sectional area in components using the B-scan detection technology of low- and medium-frequency magnetostrictive ultrasonic guided waves. This document is applicable to metal seamless pipes and straight seam pipes with an outer diameter greater than 100mm and a wall thickness of 1.4mm to 30mm, as well as metal plates with a wall thickness of 1mm to 30mm. The operating temperature range of the metal pipes and metal plates (collectively referred to as components) is between -20℃ and +200℃.
