Abstract

The invention provides a simulation experimental pipeline device of multi-phase fluid erosion and flow states. The simulation experimental pipeline device comprises a pipeline, a bracket, an erosion resistant storage tank, an erosion resistant pump, a ball valve, an electromagnetic flow meter, a resistance probe, a temperature meter, a pH meter and an oxygen dissolving analyzer, wherein the pipeline comprises an waved pipeline erosion test area and a horizontal pipeline erosion test area. The waved pipeline is simulated through the simulation experimental pipeline device with various inclined angles; the change of erosion rates is recorded in real time by virtue of the resistance probe; an annular sample of which the diameter is the same with the inner diameter of the pipeline is adopted in the horizontal pipeline area. A weight loss method and an electrochemical method are used for monitoring the internal erosion of the pipeline, and the flow states and the multi-phase fluid erosion at an industrial site can be truly simulated, so that the technical problem that the flow characteristic and erosion behavior in a flowing pipeline at an industrial site cannot be truly reflected through indoor dynamic erosion simulation is solved.
