The high-temperature and high-pressure corrosion tester is an instrument used to evaluate the corrosion resistance of materials in high-temperature and high-pressure corrosive environments, and is widely used in materials science, chemical engineering, power, aerospace and other fields.
The high-temperature and high-pressure corrosion tester evaluates the corrosion resistance of materials by simulating the high-temperature and high-pressure environment they encounter under actual working conditions. Its structure usually includes a reaction vessel, temperature control system, pressure control system, stirring system, sample device, and data acquisition system. During the experiment, place the sample to be tested into the reaction vessel and add an appropriate amount of corrosive medium. Then, the temperature and pressure inside the reaction vessel are adjusted through a temperature control system and a pressure control system to achieve the predetermined experimental conditions. The stirring system maintains the dynamic state of the corrosive medium, and the data acquisition system monitors and records experimental parameters and the corrosion condition of the sample in real time.
Generally includes heating device, temperature automatic control device, pressurization device, and metal corrosion testing device. The heating device consists of a heater shell, insulation medium, heater inner shell, high-temperature heat transfer oil, electric heater, etc; The temperature automatic control device consists of a digital temperature controller, transformer, rectifier bridge, DC relay, and temperature sensor; The pressurization device consists of a pressure pump, a precision pressure gauge, etc; The metal corrosion testing device consists of a testing kettle, a high-pressure sealing cover, a hanging bracket, temperature measuring holes, and pressure measuring holes.
