| 摘 要： | 本文在文献1]的基础上,进一步讨论了平面内不对称的“L”形及“U”形架空热力管道的热胀位移和支架处摩擦力的计算,计算中考虑了管道内压对弯头柔性系数和管道位移的影响。文中给出了计算实例,并编制了计算机程序以便于工程设计使用。本方法也可适用于两个固定支架之间的其它形式的架空热力管道系统。

| Abstract: | This paper gives a further analysis of the thermal expansion displacements on unsymmetrical "L" type and "U" type of heating pipelines. The effects of piping internal pressure on the flexibility factor of pipe bends or elbows and the displacements of pipelines are considered as an additional temperature change. A computer programme has been developed for engineering design. |
