Abstract
Immersion corrosion weight loss testing,polarization curves,EIS,SEM and EDS were employed to analyze the corrosion behavior of 16Mn steel coupons in precipitation water in Russian crude oil pipelines.The results showed that precipitation water mainly contained Cl- and SO2-4.The corrosion mode was mainly uniform corrosion.The dense corrosion product scale was composed of Fe2O3.
