Research Progress of Erosion Wear Theory of Gathering and Transportation Pipes

The development process of erosion wear theory research in the past 60 years is reviewed, the content and limitations of various mainstream erosion wear theories are analyzed, and the research and discovery of the influencing factors of erosion wear in various stages are summarized. The conclusion is that erosion wear is affected by many factors, which is difficult to be explained by a universal theory. It is believed that the research direction of erosion wear theory should focus on the test of highly reduced erosion conditions, supplemented by numerical simulation analysis, and combined with the comprehensive research of macro and micro.
