摘 要：
【Objective】To better understand the pipeline erosion-corrosion apparatus, in order to do research on the erosion corrosion behavior and mechanism in pipeline. This study would provide a theoretical basis for the mechanism of a pipeline erosion-corrosion apparatus.【Method】This paper has summarized the research status of a pipeline erosion-corrosion apparatus from China and other countries, reviewed single phase flow, two-phase flow and multi-phase flow of erosion-corrosion apparatus.【Result】Most pipelines erosion-corrosion apparatus from other countries used PLC as the main control unit to control temperature and flow. Different control algorithms had different effects on the precision of the control system, and the numerical simulation played an important role in the corrosion research.【Conclusion】In order to solve the problem of large area and low control precision in a pipeline erosion-corrosion apparatus, relevant suggestions have been made. The test device needed to perfect the control algorithm, increased the test device and on-line monitoring should be applied..
