Abstract
This article presents the results of corrosion studies of pipe steel 17G1S in oil with an allowable amount of bottom water (according to GOST R 51858-2002, MOD и ST RK 1347-2005) on a model laboratory circulating plant. For the study, 5 types of commercial oil were used, as well as bottom water (from process of final separation of oil at stations for the preparation of used types of oil). According to the results of analysis of the physicochemical properties of samples, corrosive components were determined both in oil (sulfur, mercaptans and chloride salts) and in bottom water (in the form of chloride ions, sulfate ions). Based on the obtained data on the corrosion rate of coupons made of steel 17Г1С, it was defined that the maximum allowable amount of aqueous phase (with aggressive components dissolved in it) contained in commercial oil (according to standards), increase the corrosion rate by an average of 5…12 times, compared with oil containing trace amounts of water.
