Corrosion coupon monitoring, as one of the fundamental techniques for corrosion assessment, offers simplicity in operation and high data reliability. It serves as a vital criterion for equipment and pipeline material selection. Shengli Refinery currently employs two primary corrosion coupon monitoring methods.

When positioning probes, it is crucial to consider the desired test conditions, particularly temperature and flow rate

​Over the years, the technology behind electrical resistance probes has undergone significant advancements, transforming it from its early manual and portable form to an advanced automatic recording system capable of online monitoring. This evolution has made resistance probe monitoring a standard practice in China's refining sector post-2000. The technology is highly regarded for its exceptional sensitivity, rapid response, robust anti-interference capabilities, and broad applicability.

Corrosion Monitoring Probes are key in checking and managing how much corrosion is happening, and they give important information that can help stop potential issues and keep our systems working well.

Corrosion monitoring is crucial for maintaining metal structures. Electrical Probes offer advantages such as non-intrusive monitoring, temperature compensation, and compatibility with corrosion protection measures.

Resistance probe measurement can track the corrosion behavior of metal surface in real environment. It can also master the corrosion rate and corrosion condition. Therefore, we can take corresponding anti-corrosion measures in time. Or take timely measures to control the corrosion rate within the required range. The establishment of resistance probe measurement method can timely display the corrosion of equipment and pipelines, quickly find abnormal corrosion conditions, and avoid safety production caused by equipment corrosion. It is an effective corrosion detection method.
