“…However, in the production process, C110 steel is still subject to complex corrosion of CO 2 , hydrogen and many complex stresses, causing corrosion and perforation of the casing and even fracture [6][7][8]. CO 2 corrosion has always been a problem that cannot be underestimated in the development and transportation of oil and gas industry [9][10][11]. China's oilfields are generally acid-based wells dominated by CO 2 .…”

In this study, the effects of hydrogen on the electrochemical behavior and stress corrosion behavior of C110 steel in CO 2 environment was explored by electrochemical hydrogen charging, four-point bending stress loading and electrochemical test. The results show that with the raise of applied stress, the film resistance, transfer resistance of corrosion products decrease, and I corr increases. After hydrogen charging, C110 steel has greater activity, and the combined action of external stress further promotes the corrosion reaction. The application of stress will destroy the formation of corrosion product film and reduce its protection. However, when the stress is further increased to 102%σ s , the larger grains will be broken into smaller grains, so that the surface area of the film will be increased again and the protection of the substrate will be enhanced. The main corrosion products analyzed by XRD are α-Fe, Fe 2 O 3 and MgFe 2 O 4 . The applied stress will not change the phase composition of the corrosion products.

“…[1][2][3][4] A great amount of research has been done on CO 2 corrosion to date, both experimentally and theoretically. [5][6][7] The results of this research have shown that corrosion can be influenced by CO 2 corrosion scale, which can be affected by many factors, including temperature, CO 2 partial pressure, flow, and pH.…”

Corrosion experiments were performed with low-carbon microalloyed steel under static and flowing carbon dioxide (CO 2 ) conditions at different exposure angles. The results showed that the sample facing downward had the lowest corrosion rate, while the sample that was vertically situated had the highest, under static condition. The corrosion scales were studied by scanning electron microscope (SEM), electrochemical impedance spectroscopy (EIS), and Cu Kα x-ray diffraction (XRD). The morphology, impedance, and residual stress of the scales were found to differ, but the compositions were the same under the static condition. When the sample was vertically positioned under static condition, the possibility of localized corrosion occurrence increased. The scale with higher fracture toughness provided better protectiveness. However, under the flowing condition, the exposure angle did not affect the corrosion behavior of low-carbon microalloyed steel.

“…In the study of the localized corrosion problems, the monitoring of the localized corrosion rate is the most concerned problem because it directly reflects the failure risk of the steel structure . However, traditional corrosion monitoring techniques such as linear polarization resistance (LPR), potentiodynamic polarization (PDP), electrochemical impedance spectrum (EIS) techniques can only reveal the general corrosion status of the steel .…”

In this paper, a new kind of multi‐electrode sensor system was developed for the study of the localized corrosion of the X65 pipeline steel caused by mineral deposit in oxygen containing solution. The electronic resistance (ER) method and zero resistance ammeter (ZRA) technique were simultaneously used for the monitoring of the corrosion depths and galvanic currents. The new sensor system showed a wider application range in the monitoring of the corrosion depth compared with traditional electrochemical methods. It also presented high measurement accuracy in the corrosion depth measurement. The test results revealed that the mineral deposit and heterogeneous distribution of the rust layer on the steel surface will cause inhomogeneous corrosion process. The deposit‐covered area will always act as anode and serious localized corrosion will occur beneath the sand particles. The ER method is not an in situ monitoring technique. The excitation current used in ER measurement will lead to a charging and discharging process of the double electrolyte layer on the steel surface.
