摘要： This invention is directed to a method of inhibiting corrosion-erosion in pipelines carry slurries. The method includes contacting for a period of at least 1 hour an inner surface of the pipeline with a composition of matter, the composition being at least one corrosion inhibitor within a water solvent, purging the pipeline of the water, and then transporting a slurry through the pipeline. This method is surprisingly effective because it prevents erosion with materials that were previously known to not have any effect on erosion. In addition it is effective on especially hard slurries such as bauxite for which previous uses of these inhibitors did not prevent erosion.
