摘　　要：在外压(或真空)压力管道在设计中,为了节约成本,优化设计,往往需要在管道上设置加强圈,但在GB/T 20801-2006《压力管道规范-工业管道》颁布之前,对管道加强圈的设计计算没有具体的设计规范,一般都是根据个人经验进行管道加强圈选型和设计。文中根据GB/T20801.3-2006的规定,结合GB 150.3-2011《压力容器》第4章的规定,对外压(或真空)压力管道加强圈的设计计算方法进行系统的整理,通过计算,一方面可以指导设计人员对管道加强圈的截面形式进行合理的选择,以便制作和施工的方便;另一方面可以对优化管道设计有一定的指导作用,做出经济性比较高的管道加强圈设计。In design of the external pressure （ or vacuum） pipeline, the reinforcing pad will always be used to save cost and to optimize the design. However, before the issue of Code for pressure pipeline - industrial pipe- line （ GB/T 20801 - 2006）, there are no any codes for the calculation of reinforcing pad and relevant selection and design are carried out based on personal experience. This paper systematically sorted out the calculation methods of reinforcing pad in design of external pressure （ or vacuum） pipeline by consulting the code of GB/T 20801.3 - 2006 and Chapter 4, code for Pressure Vessels （ GB 150.3 - 2011 ）. According to the calculation, on the one hand it will be easier for designers to select the reliable section form of reinforcing pad and thus help facilitate the manufacture and construction ; on the other hand, it can optimize the design of piping and make the design of reinforcing pad more economic.
