基于FSM的管道腐蚀监测技术实验研究

Experimental Research on Pipeline Corrosion Monitoring Technology Based on FSM

FSM作为一种新型的管道在线腐蚀监测方法,具有良好的应用前景。压力管道腐蚀缺陷中以局部小腐蚀坑最为常见,这也是FSM方法中研究的重点。本文基于FSM方法对压力管道常见的圆形和矩形小腐蚀坑展开实验研究,结果表明FSM方法对于小体积型缺陷敏感,实验中监测精度为0.5 mm,并可准确反映缺陷增长过程,对管道安全运行具有重要意义。

FSM,as a new on-line corrosion monitoring method,has a good application prospect.Small corrosion pits are the most common in pressure pipelines,and they are also the focus of FSM research.Based on the FSM method,this paper carries out experimental research on the common circular and rectangular small corrosion pits of pressure pipes.The results show that the FSM method is sensitive to small volume defects,can monitor small corrosion pits with a minimum depth of 0.5 mm,can accurately reflect the growth process of defects,and is of great significance to the safe operation of pipes.
