摘要
介绍了国内外管道内腐蚀检测技术的发展状况 .针对国外先进的漏磁法智能爬行机和超声波智能爬行机 ,分析了其检测管道内腐蚀的原理 ,以及这类智能装置的基本组成和工作过程 .
A pig is a equipment for pipeline internal corrosion detection. The overseas applications of magnetic leakage intelligent pigs and ultrasonic intelligent pigs are introduced. And the constituent and operating principle of the intelligent pigs are discussed. It is pointed that there is the gap between our country and the advanced countries in pipeline internal corrosion detection technology. some problems are proposed which need to be solved urgently.
