Experimental Research on High-Temperature Pipe Corrosion On-Line Monitoring

Nowadays, Ultrasound guided wave has adapted to the monitoring corrosion of pipeline at room temperature, but not worked well at high temperature. This paper introduced the basic theory of guided wave on high temperature on-line monitoring; based on some research on the test pipeline, we researched the technology of high temperature on-line monitoring, and made use of the technology on 7 high temperature pipes in Catalytic Cracking Unit to obtain the monitoring the corrosion of high temperature pipeline based on the magnetostrictive effect of guided wave technology by taking one of them as an example to monitor its corrosion and analysis the data.
