“…In this system, the cathodic process of corrosion is caused by the hydration of CO 2 and the reduction of O 2 in water. Due to high pressure, the concentrations of HCO 3 − , CO 3 2− and dissolved oxygen in the thin layer solution increase, and the cathodic reactions involved are as follows.…”

“…1,2 During the pipeline gathering process, natural gas commonly contains impurities including free water, H 2 S, and CO 2 , which can corrode the inner wall of the pipeline. [3][4][5] The occurrence of CO 2 corrosion on the inner surface of pipelines used for natural gas gathering and transportation is a prevalent form of acid corrosion. 6,7 Acid corrosion was rst reported in a Texas well in 1940, and since then, it has remained a persistent issue in various oil elds worldwide.…”

The complex research of influence of a structural condition of metal on resistance to corrosion destruction of the low-alloyed steel, operated in biocorrosion environments, is conducted. It is established that the ferritic component of a structure resists better in the environment modeling conditions of impact of biogenous gases on metal under the exfoliated anticorrosive covering. Ferrite – carbide mix, in the form of beynit, has a bigger resistance in the environment reproducing conditions of lack of biogenous factors. Existence in beynitny structure of a martensitic component leads to the largest resistance of biocorrosion in the environment modeling conditions of anaerobic corrosion with biogenous gases.

“…The sulfate reducing bacteria (SRB) as a kind of microorganism widely existed in soil, sea, river water, underground pipeline, oil gas well, and so on, and they made the pipeline more prone to perforation in the solution with SRB. So the metal corrosion caused by SRB in recent years was taking more and more attention; there have been massive researches about SRB corrosion on emergence [15][16][17][18] and some reporting about metal corrosion under disbanded coating [19,20], but up to now, there was no study on the SRB corrosion behavior under disbonded coating. Therefore, we built a rectangle crevice device for the metal corrosion under disbonded coatings and researched the regularity of SRB corrosion on …”

A rectangle disbonded coating simulation device was used to research the effect of sulfate reducing bacteria (SRB) on the metallic corrosion behavior under disbonded coating by the electrochemical method. The results showed that the metal self-corrosion potential at the same test point had little change in the initial experiment stage, whether the solution was without or with SRB. The potential amplitude in the solution with SRB was larger than that without SRB in the later corrosion period. The corrosion current density of the metal at the same test point increased gradually over time in the solution with or without SRB, and SRB could accelerate the corrosion of the metal in the disbonded crevice. The metal self-corrosion potential in the crevice had little change in the SRB solution environment after adding the fungicide, but the corrosion current density decreased significantly. That meant the growth and reproduction of SRB were inhibited after adding the fungicide, so the metal corrosion rate slowed down. Among the three kinds of solution environment, increasing the coating disbonded thickness could accelerate the corrosion of the metal in the crevice, and it was the largest in the solution with SRB.
