Abstract

The concentrations of dissolved oxygen, pH value and the other chemical factors, dramatically change in the thermocline of the tropical oceans. There is superior influence of the temperature and the dissolved oxygen concentration upon the corrosion of pipeline steel in the thermocline. With the decreasing of temperature and increasing of dissolved oxygen, the OCP of pipeline steel in the thermocline of tropical oceans rises. With the decreasing of temperature and dissolved oxygen, the Ecorr drops down and Icorr enlarges. If the pipeline steel is placed through the thermocline, the corrosion would occur that caused by the temperature difference and the oxygen concentration difference. The influence of the oxygen concentration on the corrosion was of significance.
