摘要:

钢结构系统管廊以其大体量和动辄数公里的长度,在石化项目的钢结构用钢量中占据较大的比重,因此优化系统管廊布置以节约钢材具有很重要的意义。通常来讲,管廊跨度由上游专业管道布置决定,但结构专业可以在前期与上游专业共同确定方案,通过对管廊榀距进行控制来达到优化设计的目的。文中提出了一种能够代表整个项目系统管廊用钢量方案对比的普遍性方法,通过对具有代表性的6 m、9 m两种榀距的纯钢结构双跨系统管廊的用钢量进行对比分析,得出6 m榀距的管廊造价更经济,是优化的设计。

Abstract:

Steel structure pipe racks, characterized by their large volume and lengths often spanning several kilometers, account for a significant proportion of the steel consumption in petrochemical projects. Therefore, optimizing the layout of pipe racks to save steel is of great significance. In terms of design, the span of pipe racks is usually determined by the piping layout of upstream disciplines. However, the structural discipline can collaborate with upstream disciplines in the early stages to determine the scheme and optimize the design by controlling the bay spacings of pipe racks. This paper proposes a universal method that can represent the entire project's steel consumption for pipe racks. By analyzing and comparing the steel consumption of representative double-span steel structure pipe racks with bay spacings of 6 meters and 9 meters, it is concluded that the pipe rack with a 6-meter bay spacing is more economical and represents an optimized design.
