FIELD: oil and gas industry.
SUBSTANCE: invention relates to the protection of objects from corrosion, namely to devices for electrochemical tread protection of oil and gas pipelines – field, well, main pipelines, pipelines of oil refineries, water pipelines, etc. The device contains flanged insert 1 installed in pipeline 2, tribogenerator 3, the working elements of which are made in the form of replaceable cartridges, each of which is disk 4 with holes 5, between which rods 6 are located at opposite ends of the disk. Aluminum current collector 7 is installed at the end of the flanged insert, while the cartridges are connected to each other and to the flanged insert by aluminum wire 8, and the current collector is connected by aluminum wire 9 with aluminum tread element 10 sunk into the ground.
EFFECT: use of the proposed device makes it possible to reduce the corrosion rate of the pipeline by 70-80%, which increases the duration of the inter-repair period of the pipeline and, accordingly, reduces operating costs.
