国内外管道腐蚀检测技术的现状与发展

综述了国内外管道腐蚀检测技术发展的现状，并对当今国外比较先进的管内智能爬机检测技术进行了介绍，通过分析国内外的差距，指出目前管道腐蚀检测技术的发展趋势就是使用管道内检测技术，结合国外爬机的使用情况，对国内在这方面的研究提出了建议。

Present Situation and Development of Pipeline Corrosion Inspection Techno- logy at Home and Abroad,

This paper provides an insight into the present situation and the latest development of pipeline corrosion inspection technologies of the world. The foreign advanced intelligent pigs used for inside pipeline corrosion inspection are described. After analyzing the technological gap between the advanced countries and our country,it becomes clear that using the intelligent pigs to detect the pipeline corrosion has become the trend of the world. Combining with the problems existed in application of the foreign pigs, some suggestions of the study on intelligent pigs are proposed.
