球罐安全评定方法的比较

Comparison of the Safety Assessment Methods of Spherical Tanks

利用CVDA-1984《压力容器缺陷评定规范》及《在用含缺陷压力容器安全评定》对含缺陷的球罐进行断裂与塑性失效安全评定,并分析比较所运用的评价方法。结果表明,《在用含缺陷压力容器安全评定》标准更具有优越性。

The fracture and plastic failure safety assessments of spherical tanks were made by using 《CVDA- 1884 Pressure Vessel Defect Evaluation Code》 and 《Safety Assessment for In-Service Pressure Vessels Containing Defects》, the used methods were analyzed and compared, It shows that 《Safety Assessment for In-Service Pressure Vessels Containing Defects》 is more superior.
