Diagnostics of corrosive state of main gas pipelines with module probe technology

A new method of measuring the corrosion rate of pipelines based on integration of the principle of polarization resistance into the module probe technology is developed for diagnostics of the corrosive state of pipelines. The experimental setup and the method for measuring the corrosion rate of metal objects in soil are developed. The efficiency of the setup and the possibility of recording the corrosion rate under the condition of long preliminary polarization are demonstrated. The results are of interest for development of new variants of diagnostics of the corrosive state of underground metal objects, technical diagnostics, and studies of physicomechanical characteristics of materials.
