摘要

Pipelines are an important asset in the oil and gas industry. Pipeline corrosion is a common and critical issue, the quantitative assessment and monitoring of such issue are still challenging tasks. In this paper, the piezoelectric stack corrosion measuring probe was applied to pipeline corrosion monitoring. The probes and the probe that installed on the pipeline section were fabricated, and subjected to rigorous accelerated corrosion tests. Practical issues related to the application of the probe were considered and discussed, such as the finite element verification, the influence of the tightening load, the improved load isolation connection design, the realistic corrosion monitoring for the pipeline section, and the quantitative corrosion assessment indicator. The results show that the peak frequency corresponding to the longitudinal vibration mode in the conductance signature is increased with the increase of corrosion duration, which makes quantitative corrosion assessment possible. The improved load isolation connection can effectively eliminate the influence of tightening torque. The peak frequency can serve as an effective indicator for quantifying the pipeline corrosion.
