THE EFFECT OF CORROSION DAMAGE ON THE OPERATION OF PIPELINES

Abstract

Corrosion in trench-dipped pipelines occurs in areas of contact with soil and air, in areas of transition from one to another, and this can be a very serious cause. The purpose of this article is to study the effect of heterogeneous coatings applied to the surface of pipelines at the soil-air boundary on the rate of corrosion. Standard accepted methods can be used to study the electrochemical effects: the pH of the medium in which the pipe is laid and the difference between the electrode potentials on the metal surface of the pipe. During the testing of pipes, they should be covered with anticorrosive coatings.The purpose is to determine the extent to which anti-corrosion coatings during corrosion affect the corrosion of the pipe, which leads to a reduction in the rate of corrosion, while sharply reducing the depth of the wounds, which means a 20% reduction in metal loss. Keywords: main pipe, corrosion, differential aeration, protective coating.
