摘要
管道的泄漏和破裂会产生巨大的损失,加强管道腐蚀缺陷检测具有重要意义。文中通过埋地钢管的腐蚀形态及影响因素的分析,总结了现有的各种非开挖检测技术和无损检测技术的优缺点及适用范围,并在此基础上分别从原因、过程、结果 3个层面探讨了相关在线监测技术,对实际应用和研究工作具有借鉴意义。
Pipeline leak and rupture can produce huge losses,it is of great importance to strengthen detection of the pipeline corrosion defects. In this paper,the corrosion morphology and corrosion factors of burried steel pipeline were analyzed,then advantages,disadvantages and applicable scope of the existing various non-excavation detection technology and NDT technology were summerized. Related on-line monitoring technology was discussed from the aspects of cause,process and results,which has reference significance to the practical application and research work.
