Abstract The effect of SRB+IOB on corrosion behavior of X100 pipeline steel in simulated solution of Yingtan soil was studied by mass-loss mea-surement and surface analysis techniques. The results showed that corrosion of X100 pipeline steel in sterile simulated solution belonged to moderate corrosion. With time increasing the corrosion rate first decreased and then increased slowly. The corrosion product in sterile simulated solution was Fe2O3. Corrosion after soaking for 5 d in SRB+IOB simulated solution belonged to high corrosion, while corrosion after soaking for 17 d and 40 d belonged to moderate corrosion. With time increasing the corrosion rate decreased constantly. The corrosion products in SRB+IOB simulated solution were FeS and Fe2O3. The general corrosion of X100 pipeline steel was aggravated by SRB+IOB. But the effect of localized corrosion will be dramatically suppressed soaking 5—17 d by composite films combined with biofilms and corrosion products in a short time.
