【 摘 要 】

Corrosion monitoring methods and pH measuring devices are studied. Considering the heterogeneity of the soil pH, depending on depth and sampling points, it is advisable to use solid-state potentiometric sensors that are capable of pH measuring with an error not exceeding 0.2 pH units. In the process of the pipeline installation necessary to control the soil pH value. While it is impossible to predict what kind of horizon will be in contact with the pipe material at different points. This problem requires future development of technique for the correct pH measuring for the purpose of mobile pipeline corrosion monitoring. When using cathodic protection has been required find the balance between the parameters which prevent the corrosion reactions and also take into account the hydrogen absorption on surface of the pipes material.
