摘要

为了在管道设计中合理选择支吊架间距

达到高质量、低造价的目的

本文比较分析了不同标准对管道支吊架间距计算中强度条件的弯曲应力、刚度条件的弯曲挠度及固有频率等要求

并以某电厂已投运超超临界660MW空冷机组几种常用管道支吊架间距计算为例

得出国内管道支吊架间距计算可划分为电力行业和石化行业2种模式

2种模式的计算公式基本一致

但因行业特点和相关数据取值不同

造成管道支吊架间距计算值的差异较大。建议在修订《管道支吊架第1部分:技术规范》(GB/T 17116.1)时综合考虑各个行业的设计特点和要求

统一相关数据的取值

以保证管道系统的安全运行。

Abstract

In order to achieve reasonable hangers and supports interval with high quality and low cost

this paper comparatively analyzes the calculation methods for pipe hanger interval according to different rules.It focuses on the bending stress of strength condition and bending deflection

natural frequency of stiffness condition.Moreover

these methods were used for interval calculation for several common pipe hangers in an ultra-supercritical 660 MW unit air cooling power plant.It concluded that the domestic pipe hanger interval calculation can be divided into two categories

the domestic power industry mode and the petrochemical industry mode.These two models are basically similar

but manifold industry features and relevant evaluations cause huge calculation difference.It is recommended that when the Pipe Hangers Part 1:Technical Specification GB/T 17116.1is amended

overall industry design characteristics and requirements shall be taken into account

so as to ensure the safety operation of the pipelines.
