Applicability of Cathodic Protection Probe in Western Typical Soil Environments

Three kinds of cathodic protection test probes, such as integral electrolyte type test probe, integral solid zinc test probe and reference electrode replaceable test probe, were researched and designed. A one-year applicability study was conducted in four typical western soil environments, including desert, gobi, farmland, and wetland. The results show that had the highest reliability in the four environments. In the desert environment, the plug-in reference electrode of the reference electrode replaceable test probe was easy to be checked and replaced, and close to the pipeline and thus can effectively measure the cathodic protection potential in desert areas.
