加氢精制装置分馏塔顶油气线的管道设计

Piping Design for Oil Vapor Line on Top of Fractionating Tower in Hydro-refining Unit

在加氢精制装置管道设计中,分馏塔顶油气管线是具有代表性的重要管道。文章从平面布置、管道设计、应力分析和支吊架设置等方面对分馏塔顶油气管线进行了分析比较。对分馏塔顶油气管线的管道设计优化和支吊架的合理设置,可以降低管道对设备嘴子的受力,提高该管系及设备的安全性。

The pipeline on top of fractionating tower is a typical important pipe. Its design is analyzed in aspects of layout plan, piping design, stress and spring design. Through design optimization of the pipe and reasonable arrange of support and hanger, the measures has reduced the stress of equipment nozzle and improved the security of piping and equipment.
