Dual-loop corrosion monitoring system
System Overview
The Dual-Ring Corrosion Monitoring System (RPCM) centers on a dual-ring resistance sensor and calculates the circumferential corrosion depth of a pipeline by measuring the resistance in each segment of the annular sensor. Compared with conventional corrosion detection methods, the RPCM eliminates the need to drill holes in the pipeline surface, offering enhanced safety while preserving the structural and electrochemical integrity of the pipeline. Its monitoring results are direct and reliable, effectively addressing the challenge of localized corrosion damage monitoring in complex “multiphase flow–pipeline wall” environments and enabling online, full-circumferential monitoring of internal corrosion depth.
Basic Principle
The dual-ring sensor consists of a corrosion ring and a reference ring. The inner surface of the corrosion ring is in direct contact with the corrosive medium, while the inner wall of the reference ring is coated with a corrosion-resistant layer. Each ring is divided into six equal measurement zones, and the corrosion depth in each zone is calculated by measuring changes in electrical resistance.

Product Features
♦ No need to drill holes in the pipeline surface, ensuring high safety and maintaining the structural and electrochemical integrity of the pipeline;
♦ It can distinguish between different types of pipeline corrosion (uniform corrosion, top-side corrosion, under-deposit corrosion, and erosion-corrosion), providing guidance for subsequent corrosion protection measures;
♦ The software system can calculate the corrosion rate based on the measured corrosion depth and, in conjunction with relevant codes and standards, predict the remaining service life of the pipeline.
♦ A wired network can be established via communication cables to transmit data to the central control center at the terminal, which is then integrated into the user’s comprehensive data management platform, thereby ensuring data security.
