摘　　要：评估服役多年压力容器壳体材料剩余的使用期,均基于腐蚀及疲劳损伤的原理进行评测。对于服役多年的压力容器壳体,当壳体材料的力学性能指标下降后,如何合理地评估,在国内外标准中,尚未有明确的规定。现以某型高压加热器为例,评估了旧壳体材料的力学性能。The remaining service life of pressure vessel shell materials in service for many years is evaluated based on the principle of corrosion and fatigue damage.For pressure vessel shells in service for many years,when the mechanical properties of shell materials decline,how to evaluate them reasonably has not been clearly defined in domestic and foreign standards.Taking a high pressure heater as an example,the mechanical properties of the old shell material are evaluated.
