| Abstract: | A corrosion failure analysis of 13Cr steel oil pipe was conducted by means of OM、SEM and XRD techniques.The results showed that the inner-wall corrosion of the oil pipe was induced mainly by the synergistic effect of CO2 and Cl- in the medium.The existed crevices also play certain role in the corrosion case. |
