The pressure swing adsorber is a key equipment in hydrogen production units,which has been in long-term service under alternating load conditions.Multiple incidents of cracking and leakage of pressure swing adsorbers have occurred domestically.After analyzing the failure mechanism of the pressure swing adsorber,it was found that the effect of hydrogen embrittlement could be ignored when the pressure swing adsorber operated at atmospheric temperature.When using the second stage of fatigue crack propagation rate curve to evaluate fatigue life,the effect of hydrogen on fatigue crack propagation could be ignored.
