| Abstract: | The corrosion performance and inhibition method of pipeline steel in seawater were investigated by potentiodynamic method.One of the main reasons responsible for the corrosion of sea pipeline equipment is oxygen corrosion in sea water. Under the action of catalyst the deoxidizer sulphite may be adopled as the main inhibitor, which can intensively inhibit the cathodic corrosion process caused by cathodic depolariser of oxygen and thus the corrosion rate of the pipeline steel decreased from 0.87mm/a to less 0.06 mm/a. |
