Abstract
We study the composition of deposits on the internal surface of the Kremenchuk–Kherson oil pipeline and the corrosion damages of its top and bottom fragments. We show that, in the main, corrosion damages are attributable to the presence of groundwater. We have established that the corrosion resistances of operated and nonoperated pipe steel in groundwater are different. In mixed oil–water media, the corrosion rates of degraded and nondegraded steel are practically identical but, if there is no mixing, degraded steel corrodes 1.4–1.6 times faster.
