摘要：

The effect of a low concentration of hydrogen sulfide (H2S) on corrosion resistance of low-carbon pipe steel in media with a moderate carbon dioxide gas content is studied. Presence of hydrogen sulfide within carbon dioxide atmospheres in an amount of not more than 65 mg/liter reduces the continuous corrosion rate for low-carbon steels by a factor of 4-5. A reduction in corrosion rate is due to the formation of sulfide film corrosion products on the surface of specimens in the presence of hydrogen sulfide that protects a metal surface from subsequent carbon dioxide corrosion.
