《GB/T 15830-1995钢制管道对接环焊缝超声波探伤方法和检验结果的分级》由TC56(全国无损检测标准化技术委员会)归口,主管部门为国家标准化管理委员会。
本标准规定了检验焊接接头缺陷,确定缺陷位置、尺寸、当量及缺陷评定的一般方法和检验结果的分极方法。本标准适用于制作、安装和检修设备时壁厚为15~120mm,标称直径≥159mm的钢制承压管道对接环焊缝焊接接头超声波探伤和检验结果的分级。本标准不适用于铸钢、奥氏体不锈钢的对接焊接接头超声波探伤。
Scope
This standard specifies the general method for inspecting welded joint defects, determining defect location, size, equivalent and defect assessment, and the classification method for inspection results. This standard is applicable to the classification of ultrasonic flaw detection and inspection results of welded joints of butt girth welds of steel pressure pipelines with a wall thickness of 15 to 120mm and a nominal diameter of ≥159mm during the manufacture, installation and maintenance of equipment. This standard does not apply to ultrasonic flaw detection of butt welded joints of cast steel and austenitic stainless steel.
