AI Technical Summary
In arid and saline areas, deserts, and Gobi regions in Northwest China, traditional cathodic protection systems suffer from poor reference electrode stability, lack of self-feedback control, and slow response to environmental parameter fluctuations, resulting in measurement distortion and insufficient control accuracy, making it difficult to meet the corrosion management needs of long-distance oil and gas pipelines.
A combination of drought-resistant reference electrodes, copper-copper sulfate reference electrodes, and solid reference electrodes is used, along with a self-feedback control module and a multi-sensor system, to collect environmental parameters in real time. The cathodic protection parameters are dynamically adjusted by a PID controller, achieving accurate measurement and real-time regulation.
It improves the measurement stability and adaptability of the cathodic protection system, avoids measurement distortion, reduces safety hazards, extends the system's service life, and enhances control accuracy and response speed.
