Calculation and Discussion of Pressure-Temperature Limit Curves Based on RCCM Code
-
摘要: 相对于2000版RCCM规范,2007版RCCM规范对压力-温度限值曲线(P-T曲线)计算有了改进。本文针对2007版RCCM规范对计算过程缺少明确描述的问题,提出2种不同的P-T曲线计算过程。在数值算例中分别给出根据2000版RCCM规范和2007版RCCM规范得到的P-T曲线,并讨论降温速率、堆焊层等因素对P-T曲线的影响。Abstract: Comparing with RCCM code Ver.2000,some changes for pressure-temperature(P-T) limit curve calculation in the Ver.2007 are introduced,and two P-T limit curve calculation procedures are proposed based on the Ver.2007.In the numerical example,the P-T limit curves are given by the RCCM code Ver.2000 and Ver.2007,respectively.Furthermore,the effect of some parameters,such as the cooling rate and the cladding,on the P-T limit curves,is studied.
