Author Shan Qian Publish Year 2019 Pitting Behavior of L415 Pipeline Steel in Simulated corrosion of x52 pipeline steel in a simulated soil

The corrosion behavior and laws of the west-east gas pressure pipeline of L415 steel were studied in simulated leaching liquid. The failure of the L415 steel during the pressure testing process was investigated using electrochemical polarization, electrochemical impedance spectroscopy, and immersion test. The corrosion rate of the L415 steel increased with ion concentration in the Author ia Mameri, Dalila Boughrara, Jean-Paul Chopart, Abdelaziz Kadri Publish Year 2021 Anisotropy in Mechanical Properties and Corrosion of X-52 corrosion of x52 pipeline steel in a simulated soilThe effect of CO 2 on corrosion of pipeline steel in the simulated soil solution was studied by periodic purging of 5%CO 2 N 2 in the solution. As can be seen from Fig. 9, the corrosion rate is higher when there is purging of 5%CO 2 N 2.
