裂解气管道应力分析

STRESS ANALYSIS OF TRANSFER LINE

结合工程实例运用有限元分析手段,通过对支架设置、管线走向的优化对裂解气管道进行应力计算,并对裂解气大阀法兰面受力进行对比分析。提出了设计中需要注意的问题,为今后此类管线柔性设计问题的进一步优化积累经验并提供借鉴。

This paper analyzes the problems in design of process piping of transfer line from the viewpoint of piping layout,piping support and forces and moments of pipeline,TLV and decoking valve,and points out the problems to which special attention should be paid.
