Аннотация
The mechanisms and kinetics of the corrosion-mechanical failure of pump–compressor pipes made of a chromium–molybdenum 15Kh5MFBCh steel in oil-field media with high CO2 and H2S contents and bacterial contamination are studied. The carbon dioxide corrosion resistance of the 15Kh5MFBCh steel is shown to be an order of magnitude higher than that of traditionally used manganese 35G2S-type steels. A passivating film, which mainly consists of chromium oxides, forms at the metal–corrosion product interface in CO2-saturated media, and iron sulfide layers additionally form in the media saturated by CO2 and H2S. These layers break the protective film and degrade the corrosion resistance of the steel.
