Device for testing high-temperature and high-pressure corrosion rate of multi-phase medium

The invention discloses a device for testing a high-temperature and high-pressure corrosion rate of a multi-phase medium and relates to the technical field of corrosion rate testing, and the device comprises a gas-liquid stirring device, a preheater, a high-temperature and high-pressure reactor connected with a magnetic force stirring mechanism, and an inductance probe tester extended into the high-temperature and high-pressure reactor; the upper end of the high-temperature and high-pressure reactor is connected with a gas-liquid mixture injection pipeline which is further connected with the preheater, and the lower end of the high-temperature and high-pressure reactor is connected with a gas-liquid mixture discharge pipeline. The device can solve the problems that: because the reactor in the present technology is in static environment, the corrosion test only can be executed in static environment, so that dynamic environment in a pit is difficultly simulated, tested data isn't sufficiently accurate and the measuring speed is slower when hanging sheets are arranged the reactor, and only the average corrosion rate in longer time can be obtained.
