摘要: 蒸汽发生器传热管的局部腐蚀减薄及机械磨损是导致其承压能力降低而破裂的主要原因。本文借鉴极限载荷分析方法,探讨采用有限元数值模拟估算蒸汽发生器Incoloy 800传热管爆破压力(P_B)的工程方法,并在此基础上研究体积型缺陷各向尺寸对传热管P_B的影响规律。

Abstract: The local wall thinning of steam generator tubes due to corrosion and mechanical wear is the main reason decreasing the bearing capacity and the following rupture of SG tubes.Based on the theory of limit load,the numerical simulation method is used in this paper to estimate the bursting pressure of steam generator tubes.The effect of the volume defect dimensions in all directions on the burst pressure of the pipe is studied.
