摘要
本文对苯加氢装置中高温高压临氢管道服役十年后的材料进行损伤试验研究，主要是力学性能测定与分析，试验结果表明经过长期高温临氢服役后，管道材料均受到脆化损伤，塑性、延性和韧性均已下降。
The piping material degradation after ten-year service exposed hydrogen was studied by mechanical property measurements. Experiment results indecate that the piping material degradation occurs during the operation, resulting in decreases in plasticity, ductility and toughness
