摘要:

海洋平台中的排烟管温度很高.管路系统在热胀和冷缩时,会导致管系的热应力,并对连接设备和船体结构产生很大的作用力,因此膨胀节的选型,管路系统的布置,支撑类型和结构等将直接影响船体和连接机器的安全.结合工程实例,采用CAESARⅡ管道应力分析软件对高温管道进行静力学及动力学模态分析.按照大口径管道的弯头和三通的柔性系数对模型进行特殊考虑.经过模拟分析计算,证实该高温管道系统的一次应力和二次应力均满足标准要求.

关键词: 管道应力, 高温, 排烟管, 海洋平台, 大口径管

Abstract:

The temperature of exhaust pipe in offshore platform is very high. This high temperature will cause thermal stress in piping system and large force to connecting machine and hull structure during piping thermal expansion and contraction. Selection of expansion joint, pipeline arrangement, as well as type and structure of the supports have direct effects on the safety of connecting machine and hull structure. Static analysis and modal analysis are carried out with CAESARⅡ piping stress analysis software. The flexible factors of bend and tee of large diameter pipe are included as references. According to the calculation results, the primary stress and secondary stress of high temperature piping system can meet the standards.

Key words: piping stress, exhaust pipe, high temperature, offshore platform, large diameter pipe
