Background

The jet type experimental device can simulate the erosion corrosion process at any erosion speed and angle, but cannot well simulate the actual working condition, the erosion strength is higher than the actual condition, and the difference between the actual erosion condition and the actual erosion condition of a pump and a pipeline is certain. The rotary experimental device has the advantages of simple equipment, low price, short experimental period and the like, but requires stable rotation of the motor, no vibration of the rotating shaft under high-speed rotation, and incapability of truly simulating the actual working condition conditions of the pipeline (research on the scouring and corrosion synergistic effect of Tang-liquid-solid two-phase flow on the metal surface [ D ]. Welan: Welan university of Petroleum, 2018). The pipe flow type experimental device can well simulate the erosion corrosion of a pipeline under the actual working condition, can accurately control the flow rate, has a good fluid mechanics model, and has strong practical value in the experimental result (ginger dawn Xia, Lishi Zhuo, Lishui. metal erosion and abrasion [ M ].

In recent years, accidents caused by pipeline erosion damage are endless (Huohua. numerical simulation of typical pipe erosion corrosion [ D ]. Hangzhou: Zhejiang university, 2012).
