摘要: 针对列管式换热器和列管式反应器管子-管板焊接接头特点, 研制了特殊的射线数字成像自动检测系统。分析了系统的检测原理, 并对系统的总体设计作了简要介绍。通过相关试验表明, 该系统运行平稳, 快速方便, 减少了常规射线检测对环境的污染, 极大地提高了工作效率。

Abstract: Aiming at the character of welded joint of tube-tube sheet in multitubular heat exchanger and reactor, a special radiographic imaging and automatic detection system was designed. The principle of system was analysed, and the overall design was briefly introduced. Through the related experiment, it was indicated that the system ran steadily fast and conveniently, environment pollution of common radiographic testing was reduced, and the work efficiency was significantly improved.
