摘　　要：在役管道内部腐蚀及沉积程度的有效检测是石油、化工等部门亟待解决的问题。射线检测是一种有效的解决办法 ,但对包覆管道检测需进行复杂的信息处理 ,如准确快速的射线影象信息读取等。介绍管道检测及其信息提取技术的发展及存在的问题 ,并对有效的包覆管道检测技术进行了讨论。Effective detection of the corrosion and deposit inside insulated pipes is a problem that must be solved in petroleum and chemical plants. Radiographic testing is an effective way, but complicated data processing is needed, such as quick and effective data extraction. The development of radiographic testing of insulated pipes and the ways of data extraction, as well as some unsolved problems and effective testing technologies are described.
