海上油气田上部设施管道支吊架的工程设计

The Engineering Design of Piping Supports on Topside of Offshore Oil ＆ Gas Oilfield

以美国石油协会API14E和ANSI B31．3标准为基础，根据中国海洋石油工程公司的常用方法，对海上油气田上部设施管道设置中支吊架的基本形式和选用进行阐述。提供了管支吊架间距的设计方法，对管支吊架的材料选择和载荷的考虑进行分析，并根据支吊架的作用分析其在管道应力中的作用。最后给出了支吊架在工程设计中应当考虑的实际重点问题。

Based on API 14E, ANSI B31.1 and the usual ways of engineering design, The basic form and selection of piping supports on topside of offshore oil ＆ gas oilfield are introduced in this paper. This paper provides the design method of space between piping supports and the methods of selecting the pipe material in different cases and analyzes the piping supports load and piping supports function in the pipe stress. Finally the key points of the piping supports design in the practical engineering are presented.
