Corrosion and erosion remain two key issues in oil and gas industry. With energy demand increase transported through aged pipelines network, maintaining its integrity is a must to meet up the global demand, safety, and environmental regulations. In the last few years, there has been an increasing need for online corrosion and/or erosion monitoring tools for monitoring piping metal loss. On-line corrosion monitoring is an important component of any comprehensive corrosion control and integrity programs. Utilizing non-intrusive approach will provide flexibility in selecting the monitored locations in non-accessible or congested areas where intrusive devices may not have room to function. This paper will address a laboratory assessment program of a newly non-intrusive multi-sensors (transducers) corrosion monitoring tool. The evaluated technology is based on acoustic guided lamb waves (AGLW). The objectives of this laboratory assessment were to identify the applicability and limitations of this technology under simulated field accelerated corrosion conditions. Based on the obtained data, the system was able to report the wall thinning and to prove its functionality.
