Scope: This standard specifies the testing requirements, testing methods and calibration procedures for full-circumference ultrasonic wall thickness measurement of non-glued and welded steel pipes (except submerged arc welded steel pipes). Note 1: Full circumference detection does not mean 100% scanning of the steel pipe surface. Note 2: Thickness measurement can be carried out simultaneously with the full-circumference layered inspection (ISO10893-8) that can meet the inspection requirements using the same ultrasonic probe. In this case, according to the requirements of ISO 10893-8, the coverage of steel pipe surface scanning is determined by the minimum layer size required for detection. This standard also applies to the detection of circular hollow profiles. The applicable thickness measurement range of this standard is that the nominal outer diameter is greater than or equal to 25.4 mm, and the minimum wall thickness is 2.6 mm unless otherwise agreed.
