Device used in material performance test in high-temperature pressurized-hydrogen environment

Abstract

The invention belongs to the technical field of material performance, and specifically relates to a device used in a material performance test in a high-temperature pressurized-hydrogen environment. The device comprises a test kettle, a sample fixing mechanism, a measuring mechanism, and a hydrogen pressure adjusting system. A sealed inner cavity is arranged in a kettle body of the test kettle. Two joints connected with a hydrogen pressure adjusting system are arranged on the outer side of the kettle body. The sample fixing mechanism is used to be connected with a metal material performance sample arranged in the inner cavity of the kettle body, and is used for carrying out the material mechanical performance test upon the metal material performance sample. The hydrogen pressure adjustment system is used for charging hydrogen into the inner cavity of the kettle body, and for adjusting the hydrogen pressure in the sealed inner cavity of the kettle body according to a preset pressure. With the device provided by the invention, a test environment with stable temperature, pressure, and hydrogen medium can be provided for the metal material performance test under the high-temperature pressurized-hydrogen environment, such that good conditions are provided for acquiring the performance of the metal material under the high-temperature pressurized-hydrogen environment.

Description

technical field [0001] The invention belongs to the technical field of material performance testing, and in particular relates to a device for material performance testing in a high-temperature pressurized hydrogen environment. Background technique [0002] With the use of advanced chemical, petrochemical, coal chemical and other process technologies, many equipment made of metal materials work in the environment of high temperature and pressurized hydrogen gas, which leads to the deterioration of the performance of metal materials and seriously affects the safe operation of the equipment. In order to enable metal equipment to operate safely and stably for a long time in a high-temperature, pressurized hydrogen environment, it is necessary to obtain the performance of metal materials in a high-temperature, pressurized hydrogen environment. However, due to the explosive and easy-to-leak characteristics of hydrogen, existing The material testing machine cannot perform the perf...
