Assertions that dilbit is extraordinarily corrosive have delayed pipeline approvals in Canada and the US. Static 65ºC laboratory autoclave corrosion tests of pipeline steels exposed to simulated produced water covered by Canadian dilbit synbit and conventional crudes all showed comparable low corrosion rates. The oils themselves in the absence of water were non-corrosive. After testing the specimens showed no evidence of hydrogen induced cracking (HIC). Rotating cylinder autoclave tests for erosion-corrosion at 65ºC with typical pipeline oil velocities show no significant difference in corrosion rates in the oils tested. Dilbit synbit and conventional crudes show similar water breakout tendency in interfacial tension (IFT) measurements. Corrosion inhibitors prevent pitting more efficiently in dilbit than in conventional crude. Tests of corrosion under deposits showed no significant difference in corrosion rate between dilbit synbit and conventional crudes.
