Through the tests of mechanical properties of charging hydrogen and the corrosion tests in loop water of high temperature and high pressure, hydrogen brittleness of T225NG Ti-alloy was studied.
The article discusses some factors which influence the performance of the non-mechanical valve, such as system pressure, air flow-rate, air charging mode and characteristics of ash et al.
Tensile tests and slow strain rate tests (SSRT) are used to investigate the mechanical behaviors of X70 pipeline steel after electrochemical hydrogen charging.
