Abstract: The short-term corrosion behavior of X80 pipeline steel was investigated in Huo'erguosi soil with saturated water using electrochemical measurement,scanning electron microscopy(SEM) and energy dispersive spectrum(EDS) analysis.The results showed that the corrosion rate of X80 steel presented the variational trend of rapid increase→sharp decrease→slow increase with the increase of corrosion time,and corrosion tendency increases,this is induced by change of corrosion morphology from uniform corrosion to localized corrosion.The corrosion product is basically iron oxides and iron sulfides.The corrosion resistance and corrosion morphology of X80 steel samples is dependent on the integrality and compactness of corrosion product films.
