Abstract：A set of cyclic testing equipment simulating high-t emperature and high-velocity situations in oil refinery industry has been design ed and built up.This equipment is primarily used to study the erosion-corrosion ca used by high-temperature fluids.The oil medium in the cyclic testing equipment c an be heated up to 350℃ and the pressure limit for this system is 6.4 MPa.The h ighest flow velocity of the oil medium in the equipment can be up to 49 m/s at p resent.The flow field in the process of erosion-corrosion experiments realized b y using the testing equipment has been simulated and analyzed by the finite elem ent method.It is found that the larger the exit velocity and the diameter of the nozzle as well as the smaller the distance from the nozzle exit to the specimen surface,the stronger the fluid erosion.Adjusting the gradient of the specimen a nd the temperature of the oil medium can also change the erosion effect.On the b asis of the simulation results of the flow field,the experimental parameters for the fluid erosion have been selected by simultaneously considering the factual situations of the testing equipment.It has been proved by the erosion-corrosion experiments that property of the testing equipment is stable,the selection of th e experimental parameters is reasonable,and the equipment meets the demands of h igh-temperature erosion-corrosion experiments.
