对非常温管道进行正确的应力分析是管道正常、稳定运行的重要保证之一。但是否所有非常温工况、所有规格的管道都必须进行应力计算 ?或象有的设计人员认为只要多加几个弯头 ,增加管道的柔性 ,就可无需应力分析了呢 ?事实并非如此。下面简单介绍国外配管设计中判断管道是否需要 The correct stress analysis of very warm pipe is one of the important guarantees for the normal and stable operation of the pipe. But are all of the pipes under very warm operating conditions stress-relieved? Or, as some designers think, adding more bends to increase the flexibility of the pipe eliminates the need for stress analysis? This is not the case. The following brief description of the foreign pipe design to determine whether the need for pipe
