浅析工作温度、金属壁温、设计温度三者之间的关系

摘要

在压力容器的设计、制造、使用、检验等过程中都会涉及到工作温度、金属壁温、设计温度等，本文主要论述上述三者温度值的区别、计算的方法及三个温度值在设计时的选取原则。%In the design of pressure vessel manufacture, use, inspection process will involve working temperature,metal wall temperature, design temperature, etc. This paper discusses the differences between the above three temperature values , methods and values calculated at three temperatures select the design time.
