UT1024HY Metal Material Test Under Hydrogen Rich Environment Compatibility Testing Machine

1, Introduction:

The metal material hydrogen environment compatibility testing machine is mainly used for slow strain rate (SSRT) stress corrosion (SCC) testing, fatigue testing, etc. of metal materials in hydrogen environment. According to different configurations, dynamic fracture mechanics related tests can also be conducted.

The UnitedTest UT1024HY metal material hydrogen environmental compatibility testing machine adopts a frame form host structure, generally consisting of an independent loading unit, a hydrogen high-pressure test kettle, fixtures, a control system, a deformation system, measurement and control software, a hydrogen gas pressurization system, a temperature control system, a detection and alarm system, etc.

The loading unit can be flexibly installed at the upper or lower end according to the testing requirements to adapt to the testing requirements of different media environments. According to different accessories, this series of equipment can be applied to various testing environments, including extreme conditions such as low temperature (up to -55 ℃), high pressure (up to 140MPa), or other ultra-low temperature liquid hydrogen corrosive media environments.

In addition to the equipment host frame, this series of stress corrosion testing machines also have multiple optional units to achieve extended functions beyond basic testing functions.
