摘　　要：合理确定设计寿命体现设计水平,而确定设计寿命需要失效模式的控制和工程经验的积累。一般以工程经验确定设计寿命,再以失效模式控制来保障设计寿命。其中合理结构选材及确定腐蚀裕量是对腐蚀失效的控制,而合理设置安全附件又是对超设计条件失效的控制,开孔补强则是对强度失效控制之一,耐压试验是对建造的可靠性控制等,结合分气缸施工图工艺审图所发现的问题,对此进行了讨论,并给出合理的建议。Reasonable design life reflects the design level. The determination of the design life needs failure mode control and engineering experience accumulation. Usually, the design life is confirmed by engineering experience, and ensured by failing mode control. Reasonable material and structure to determine the corrosion allowance is the control of corrosion failure. Setting up reasonable safety attachment is the control of the super design conditions for the failure. Opening reinforcement is one of the controls of strength failure. Withstand voltage test is to build the reliability of the control and so on. Found with the technological plan approval points to the problems of cylinder construction drawing, which are discussed, and given reasonable Suggestions.
