Abstract:
Brazil has the expertise in dealing with ethanol anhydrous and hydrated fuels. The stress corrosion cracking (SCC) caused by these fuels has been studying lately by national and international research groups. It is known that hydrated ethanol does not harm steel facilities, but laboratory tests have shown the occurrence of SCC in API 5L X65 steel by anhydrous ethanol. In this study, anhydrous ethanol fuel samples obtained from pipeline dedicated to the ethanol fuel transport and from multi-product pipelines were tested. It was observed that the samples from multi-product pipelines were more aggressive than the ethanol fuel from dedicated pipeline samples. These results confirm that the occurrence of SCC is related to the presence of contaminants carried by the own ethanol fuel.
