Description

Technical Field

[0002] Long-term operation in a high-pressure hydrogen environment can reduce the durability of materials due to hydrogen embrittlement, potentially leading to sudden failure of high-pressure hydrogen system components and even explosions. This problem becomes more pronounced as hydrogen storage pressure increases. To ensure the long-term, safe, stable, and reliable operation of high-pressure hydrogen systems, it is necessary to test and evaluate the durability of materials in high-pressure hydrogen environments.

The air pressure in the inner cavity of the box rises until the value displayed on the barometer is the value required for the test. Close the hydrogen tank and start the metal ceramic heating element until the value displayed on the thermometer is the value required for the test. Start the hydraulic telescopic rod to move the telescopic rod downward or upward until the bottom end of the upper plate contacts the test material or the top end of the test material contacts the support plate. The telescopic rod continues to move downward or upward to compress the material between the upper plate and the support plate or the lower plate and the support plate, and observe the bending degree of the test material through the explosion-proof glass.
