Annotation:

The article discusses the relationship between environmental safety and the level of anti-corrosion systems to protect the physical integrity of gas industry facilities. The reasons that reduce the efficiency of the systems used are noted and measures are proposed to improve the manageability of environmental risk at industry facilities. The advantages of coating systems with a non-shielding effect when combined with cathodic protection are shown. In particular, the use of a functional anti-corrosion coating system with self-regulating electrical resistance developed by the authors of the article is substantiated. Local (in a defect) resistance decrease of such an anticorrosion system allows reaching high efficiency of protection even in case of adhesion aging by minimizing the risks of invisible processes of pipes walls deterioration. It is shown, that the improvement of the existing protection system leads to a decrease of the conflict with the environment at the stage of main pipelines operation.
