摘要
本文提出了一种新的蠕变变形量表达式,并提出了一种主蒸汽管道寿命预测新方法。定义了许用蠕变量[ε],提出了高温高压主蒸汽管道蠕变变形的判废准则ε≤[ε]=1.9％。
A new mathematical model for creep deformatim was set up and a new method of life prediction on main steam pipe was proposed in this paper. Degree of allowable creep [ε] was defined and the failure criterion for creep of the main steam pipe under high tempe- rature and pressure, ε≤[ε]=1.9%, was suggested.
