Abstract: Corrosion of internal surface of the field pipelines and equipment is the main reason leading to their failure. Application of corrosion inhibitors in combination with corrosion monitoring is the most common method of anti-corrosion protection, but its practicability is not always justified.
In order to assess the practicability of inhibitor protection, the authors suggest using the method of field pipeline failure forecasting based on statistical analysis of the surface relief of witness specimens after field tests in inhibited medium and in the medium without the inhibitor, and also on subsequent analysis of the failure flow. It is shown that determination of practicability of corrosion inhibitor application is reduced to the forecast of technical and economic life of the pipeline and the choice of such a period of its operation, in which the costs of the company will be minimal.

Keywords: pipeline failure prediction, corrosion, specimens, corrosion damage distribution, inhibition.
