Research progress of erosion in multiphase pipelines

Erosion in multiphase flow is very common to the industrial piping systems and it will increase the safety risk of the piping systems. Once accidents occur, it will bring about serious economic loss and environment pollution.By investigating the research on the erosion of multiphase pipelines, the progress of research at home and abroad was presented in terms of the theoretical model, the erosion test, the numerical simulation and the microscopic mechanism. Meanwhile, the existing problems in current research on erosion of multiphase pipelines were pointed out and discussed, and the development direction in future was also clarified. In general, the research results could provide reference for the deep understanding and mastering of the erosion mechanism of multiphase pipelines, as well as the safe and efficient development and transportation of oil and gas resources.
