High-temperature high-pressure multiphase flow corrosion testing device

Abstract

The invention relates to a high-temperature high-pressure multiphase flow corrosion testing device. The device is manufactured by adopting solid-forged anti-corrosion alloy steel materials with the maximum air sealing pressure being 70MPa and highest working temperature being 200 DEG C, thereby having corrosive media capable of resisting acid, alkali, chlorine and the like and remarkable corrosion resistance. A visual window arranged on the corrosion device has similar sealing property, strength, corrosion resistance, temperature resistance, thermal fatigue life and the like to those of a high-temperature high-pressure kettle, and can be used for observing flowing corrosion conditions of materials and phase states of corrosive media at different temperatures and pressures in real time. The rotating speed of a magnetic coupling agitator is numerically controlled by a computer and displayed and recorded in real time, so that the corrosive media can flow in a circulation way in the device. A support base is provided with a rotation shaft for adjusting the inclination angle (0-45 degrees) of a reactor, and a cylindrical worm, so that multiphase flow simulation demands can be met at different inclination angles. The high-temperature high-pressure multiphase flow corrosion testing device is applicable to simulating material corrosion tests under severe environments in development, gathering, transportation and processing processes of petroleum and natural gas.
