- This specification specifies the general methods for inspecting welded joint defects, determining the location, size, equivalent and defect assessment of defects, and the grading method for flaw detection results. This specification is applicable to ultrasonic flaw detection of single-sided and double-sided welded joints of steel pressure-bearing pipelines with a wall thickness of 4~120mm and a nominal diameter greater than or equal to 32mm during the production, installation and maintenance of equipment in power systems. This specification does not apply to ultrasonic flaw detection of welded joints of cast steel and austenitic stainless steel, as well as flaw detection of friction welded joints of small-diameter pipes with wall thicknesses of 4 to 14 mm and nominal diameters of 32 to 89 mm.
