本文提出的设计思想可供G E公司汽轮发电机组的用户在设计机组蒸汽管道系统布置时参考。鉴于已经出版了大量高温管道系统方面的资料,本文不再重复那些可以轻易找到的数据。只是列出了部分有关参考文献。而本文的目的是提出一些最基本的原则,同时列举一些有关G E公司汽轮机管道系统设计的特殊要求和建议。一般来说,一个管道系统是否令人满意,或者管道本身是否产生应力,其判定标准可以用某些专门的方法估算出来,并加以一定的限制。如果考虑管道系统对汽轮机的影 The design idea proposed in this paper can be used by G E Turbogenerator users when designing the steam pipe system layout of a unit. In view of the fact that a large number of high-temperature pipe systems have been published, this article will not repeat the data that can be easily found. Only some of the relevant references are listed. The purpose of this article is to present some of the most basic principles and to list some of the specific requirements and recommendations for the design of G E’s steam turbine piping systems. In general, whether a pipeline system is satisfactory, or whether the pipeline itself produces stress, the criteria can be estimated by some special methods, and to some restrictions. If you consider the pipe system shadow on the turbine
