摘要
利用CAESARⅡ应力分析程序对1000MW直接空冷机组排汽管道进行了整体应力分析。根据美国ASMEB31.1《动力管道》标准要求及工程实践经验,考虑了管道在内压、自重、热胀、基础差异沉降、地震、风载等荷载作用下管道的受力情况,并通过荷载工况的组合作用,得出各个工况下管道的应力分布和各个支吊点、设备接口的受力情况,并进行了补偿器的初步选型,为1000MW直接空冷排汽管道设计提供了解决方案。
Exhausting steam pipe for 1 000 MW direct air-cooled power plant has been strength analyzed using CAESAR Ⅱ software in this paper. According to the requirements of ASME B31.1 Power Piping and project experiences, vacuum condition, dead weight, thermal expansion, foundation settlement difference, seismic load, wind load, friction, etc. have been considered in this analysis. Based on combination actions of various loads, stress, supports loads, force and thrust on equipment connections at various conditions can be obtained. Expansion joints load and deformation can also be obtained in this analysis. The results are essential to the design of exhausting steam pipe for 1 000 MW Unit.
