国内外埋地管道腐蚀检测技术现状及展望

Current Status and Prospects of Corrosion Detection Technology for Buried Pipelines at Home and Abroad

对国内外近年来出现的管道检测技术进行整理分析,按照检测装置所处的不同位置分为管道内检测和管道外检测,前者有种五方法,后者有三种方法。简要说明了各种检测技术的原理、优缺点及其适用范围。根据工况、管径和设备自身的特点来选择最佳检测技术。最后指出优先发展瞬变电磁检测技术,并对我国管道腐蚀检测技术作了展望。

At home and abroad in recent years, the pipeline corrosion detection technology to do the analysis, based on the position detection device is placed into a different pipeline inspection and pipeline outside testing, a kind of five former method, the latter three methods. A brief description of the principles of various detection techniques, advantages and disadvantages of its scope of application. According to the conditions, diameter and characteristics of the device itself selects the best detection technology. Finally priority to the development of transient electromagnetic detection technology, and made prospects of pipeline corrosion detection technology.
