摘　　要：采用不同方法对存在裂纹的筒状压力容器的安全性进行评定,并选用无塑性变形条件下的计算公式和ASME标准进行只漏不爆判定。结果表明,该压力容器满足只漏不爆条件。Various means were adopted to assess the safety of cylindrical pressure vessels with cracks,and then the formula based on no plastic deformation and ASME standard were applied to judge the leak before break condition. The results have shown that the pressure vessels meet the requirements of leak before break.

关 键 词：压力容器 裂纹 安全性 只漏不爆
