Quality Management of LNG Railway Tanker Nondestructive Testing Process Examination

摘要: 在LNG（液化天然气）铁路罐车的无损检测工艺性审查中发现：中梁对接焊缝超声检测技术要求不明确，外罐端环缝超声检测存在盲区，三通管子环缝结构难以射线检测等。设计人员根据反馈意见，对无损检测技术要求进行了修改或补充，满足了国家相应产品法规及标准的要求，提高了无损检测的工艺性。

Abstract: The technical examination of the nondestructive testing of the LNG railway tank car found that the ultrasonic testing technology for the butt weld of the middle beam is not clear, the ultrasonic testing of the outer ring joint of the outer tank has a blind area, and the girth weld structure of the tri-through pipe joint is difficult to detect by RT, and so on. According to the feedback, the designers have modified or supplemented the technical requirements of NDT, which meet the requirements of the national regulations and standards of the relevant products and improve the technology of NDT.
