The objective of this study is to evaluate the effect of adding water at different concentrations (0.5%, 5% and 10%) in ethanol-95% gasoline and 85% (% V) of ethanol in addition to a white medium on the Corrosion Under Stress (CBT) for API 5L X52 steel, typically used in the transportation of hydrocarbons. The tests were performed at a constant rate of extension in a CERT machine at a nominal strain rate of 10-6 s-1. CERT test of simultaneous manner, using the technique of monitoring Electrochemical Noise potential noise and current noise wherein the fluctuations have correspondence with the dissolution of the material. Additionally, it is noted that evidence less in% (V) of the water present is less effective and secondary cracks in the samples analyzed for CBT test results cyclic polarization curves show no tendency to SCC. |
