钢结构对管道应力的影响研究

Study on the Influence of Steel Structure on Pipeline Stress

总结了某化工园区原料结构调整项目脱硫脱碳工段的变换气管道配管设计及应力分析,利用CASERII软件的Structural模块,将钢结构的力学特性耦合到变换气管道的应力计算中,分析了钢结构的变形特性对管道应力的影响。考虑到钢结构自身的力学特性,可以在很大程度上降低管道的柔性,节约管道及其附属材料,降低投资成本,经济效果显著。

This paper summarizes the piping design and stress analysis of the transfer pipeline in the Desulfurization and Decarbonization Section of a raw material restructuring project in a chemical industry park.Using the Structural module of CASER II software to project the mechanical properties of the steel structure onto the stress calculation of the transfer pipeline,the paper analyzes the influence of the steel structure deformation on the pipeline stress.Considering the mechanical properties of the steel structure itself,flexibility of the pipeline can be reduced to a great extent,to save materials of the pipeline and its fittings,reduce investment,and achieve remarkable economic benefit.
