Hydrogen Induced Cracking (HIC) can be a major issue for line pipe exposed to sour environments. In this study, influence of the test solutions on HIC evaluation was investigated from the view point of corrosion. Electrochemical measurements were employed to compare corrosion behavior of line pipe steels between the 0.93N acetate buffer solution and the conventional 0.05N acetate solution.
The storage and transportation of biofuels continue to be of interest. Material compatibility issues arise. For alcohol fuels, stress corrosion cracking of steels, and swelling and leaching of various polymeric materials. This paper will provide an overview of research that has been conducted in alcohol fuels.
