Abstract

Potentiodynamic polarization measurement was used to study the effects of temperature, dissolved oxygen concentration and pH value on the electrochemical behavior of X70 pipeline steel in simulated Ku'erle soil solution by orthogonal testing method. The results show that the temperature, dissolved oxygen concentration and pH value have great influence on the corrosion current density (i_corr) of X70 pipeline steel. The corrosion current density of the X70 pipeline steel is most influenced by dissolved oxygen concentration in simulated solution. The corrosion degree of X70 pipeline steel in simulated solution is lower under the environment of low temperature, oxygen deficit and weak acid that easily cause localized corrosion initiating stress corrosion cracking.
