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。
In-service pipeline corrosion and deposition of the effective detection of the oil, chemical and other departments to be solved. Radiographic testing is an effective solution, but complex information processing, such as accurate and rapid reading of radiographic images, is required for the inspection of coated pipes. This paper introduces the development and existing problems of pipeline inspection and information extraction technology, and discusses the effective cladding pipeline inspection technology.
