1.Oxygen absorption corrosion of steel caused by primary battery principle
2.Hydrogen evolution corrosion caused by polyacidic sulfide on the surface of pipeline caused by acid rain
3.Carbon dioxide acid corrosion caused by atmospheric precipitation
4.Bacterial corrosion caused by bacteria that can metabolize sulfate on the pipeline surface and corrosion caused by accumulated water in the pipeline.
