液化石油气储罐设计风险评估分析

Design Risk Evaluation Analysis of the LPG Storage

压力容器在设计时事先考虑全寿命过程中可能的主要失效模式和损伤机理产生的风险对设备安全性与寿命的影响,通过合理选材,改进结构设计、优化制造工艺等措施,在设计、制造早期控制和降低压力容器在使用过程中的风险,并结合从工艺流程上采取的措施,使其安全服役到预定的设计寿命。

The effect of failure modes and mechanisms risk to the safty and life should be pre-considered for pressure vessel design.By ration select material,configuration improvement,manufacture technics optimization,through controling and decreasing the risk of pressure vessel during usage in the design and early manufacture,with measures from the process,the safe life can achieve the desired.
