Abstract: In the light of some oil pipeline sections being subject to bursting by corrosion, size of corrosion burst area as well as size and distribution of corrosion pits are measured, ingredients of the corrosion products are analyzed by SEM and XRD, and the residual strength of corroded pipeline is calculated and analyzed. The results show that the pipe coating was peeled basically, and the most serious corrosion thinning at the cracking opening could be seen with the maximum corrosion depth of 6.03 mm, corrosion pits appeared a discontinuous distribution, a major component of the corrosion products was Fe3O4, the corrosion product layer was relatively dense with many micro-cracks subject to maximum width of 8 μm, and corrosion residual strength at the cracking opening was the lowest, only 2.07 MPa. Based on the above analysis, overall corrosion conditions of the pipeline are basically revealed, and the analysis results can be taken as a reference basis for the development of a safe operation program.
