WebMar 16, 2008 · ABSTRACT . In pipelines transporting wet gas containing with H2S and CO2, electrochemical corrosion can occur as well as Hydrogen Induced Cracking (HIC). The presence of H2S and CO2 corrosion scales influences the process of hydrogen entry into the steel. This was studied with an electrochemical cell. Perfect covering of corrosion … WebMar 31, 2014 · The corrosion process of the steels was simultaneously governed by CO2 and H2S. The outer scales on the three steels mainly consisted of FeS1-x crystals, whereas the inner scales on Cr-containing ...
