摘要: 在石油化工领域,超高压蒸汽主要用于乙烯装置裂解气压缩机的透平驱动,其输送管道具有温度高、压力高、管径大的特点。借助CAESAR II软件,在满足美标ASME B31.3要求的一、二次应力强度校核条件下,对不同管径的超高压蒸汽管道轴向位移、补偿弯臂长、补偿弯延伸量、补偿弯垂直载荷、固定端水平推力等方面进行应力分析,并进行归纳总结,分别提出了拟合公式,对工程设计领域,尤其是在前期可研、总体设计及基础工程设计阶段的工作具有一定的参考和借鉴意义

Abstract: In petrochemical industry, ultra-high pressure steam is mainly used for turbine drive of cracking gas compressor in ethylene plant. Its transmission pipeline has the characteristics of high temperature, high pressure and large diameter. While meeting the primary and secondary stress intensity check condition requirements stipulated in ASME B31.3, this paper uses CAESAR II software to analyze the stress of ultra-high pressure steam pipeline with different pipe diameters in terms of axial displacement, compensated bending arm length, compensated bending extension, compensated bending vertical load and fixed end horizontal thrust, summarizes and puts forward fitting formulas respectively, providing reference for engineering design, especially in the stages of feasibility study, overall design and basic engineering design.

Key words: ultra-high pressure steam pipeline, stress analysis, CAESAR II software, fitting formula
