SINOTEST ‘s 900°C High-Temperature and High-Pressure Hydrogen Environment Test Facility Solves Testing Challenges in Extreme Hydrogen Environments
With the rapid development of the hydrogen energy industry and research on high temperature structural materials, the safety of materials in high temperature hydrogen environments has attracted increasing attention.
Whether they are high-temperature components of hydrogen-blended steam turbines, or key materials in hydrogen engines and hydrogen transmission equipment, they must remain stable and reliable in high-temperature and high-pressure hydrogen.
However, hydrogen aggravates the embrittlement effect of materials at high temperatures; the processes of crack initiation and propagation can be significantly accelerated, leading to early structural failure.
Can we faithfully replicate the harsh service environments of these pieces of equipment in the laboratory and systematically study material performance in hydrogen environments?
The answer is affirmative. In response to the above needs, SINOTEST Equipment Co., Ltd. has developed a **900°C High-Temperature and High-Pressure Hydrogen Environment Test Facility** (hereinafter referred to as “the Equipment”).
It provides researchers with a controllable, stable and traceable extreme experimental platform, solving the testing difficulty of replicating the “high-temperature and high-pressure hydrogen” service environment in a laboratory setting.
The equipment can operate stably in a hydrogen environment at up to 900 °C and 3 MPa, offering unique conditions for studying the mechanical behavior of materials under extreme conditions.
Its development provides important support for the safety of the hydrogen energy industry chain, aerospace material validation, and the development of high-temperature alloys.
Stably reproducing extreme environments, laying a solid foundation for experiments.
The core capability of the equipment is first reflected in the high-fidelity reproduction and precise control of extreme environments.
The equipment can maintain a stable ambient temperature of 900℃ with a fluctuation of less than ±2℃, providing a stable and reliable experimental foundation for the study of high-temperature service performance of materials. Meanwhile, the gas circuit and sealing system of the equipment can withstand high-pressure hydrogen up to 3 MPa.
The apparatus is equipped with high-temperature grip.
High-Temperature and High-Pressure Environment Apparatus
The stable coupling of high temperature and high-pressure hydrogen provides a solid foundation for researchers to comprehensively evaluate the mechanical response and failure risk of materials under extreme conditions.
Full coverage of loading modes to meet multi-field coupled testing requirements.
In terms of mechanical loading and experimental capabilities, the apparatus supports a variety of loading modes including tension, compression, bending and fatigue, meeting the multi-field coupled testing requirements of materials in high-temperature hydrogen environments. Researchers can not only characterize the high-temperature strength and ductility of materials, but also investigate creep, stress relaxation and other behaviors during long-term service.
All tests of the equipment are performed under a digital control system, with fully closed-loop control over mechanical loading and environmental parameters, guaranteeing experimental repeatability and data reliability.
Crack propagation and extension reveal the hydrogen-induced embrittlement mechanism of materials.
With its unique capabilities in crack growth testing, the device enables fatigue crack growth and stress corrosion crack growth tests. Under cyclic loading, researchers can accurately measure the accelerating effect of hydrogen on crack growth rates, reveal the mechanism of hydrogen-induced embrittlement, and provide direct data support for the development of life prediction models and the evaluation of fracture toughness.
Currently, the equipment has been stably deployed in the Hydrogen Energy Materials and Safety Laboratory of Tianjin University, accurately replicating the harshest operating conditions encountered by core components of hydrogen energy systems in real operation.
The facility provides strong support for the university’s cutting-edge research in hydrogen energy safety and materials, accelerating the transition of high-performance, high-safety hydrogen energy materials from basic laboratory research to engineering applications.
With the continuous advancement of hydrogen energy utilization, the reliability of materials under extreme environments will remain a key focus in scientific research and engineering. The **900°C High-Temperature and High-Pressure Hydrogen Environment Test Facility** will continue to help researchers reveal the behavioral laws of materials in complex environments, promote the development and application of new materials, and serve energy security and engineering innovation.
