|
摘要
针对天然气管道工程用焊管相关标准的技术要求,分别给出了钢板和焊管超声波检测时的探头布置、灵敏度设置及各类缺陷的具体检测方法。分析了钢板或焊管中存在的各种缺陷的类型特征,设计了超声波检测时所用的专用探头和特殊探头。介绍了焊管生产过程中超声波检测的验收标准和特殊探头的使用方法。应用结果表明,专用探头和特殊探头的使用,提高了焊管在线检测效率,降低了材料损耗,确保了焊管产品质量。
Aiming at technology requirements of relevant welded pipe standards used for petroleum and gas pipeline project, in this article, it respectively provided probe display, sensitivity setting and specific detection methods of all kinds of defects in ultrasonic detection of steel plate and welded pipe. The type characteristics of various defects existing in the steel and welded pipe type were analyzed; the special probes used in ultrasonic detection were designed. It also introduced acceptance standard and application method. The usage of dedicated probes and special probes increased online detection efficiency, reduced material wastage, and ensured welded pipe quality.
