摘要:
为了保证某集气站改建的放空管道安全运行, 对其设计方案进行管道应力优化研究。利用CAESAR Ⅱ软件分别对管道设计压力, 操作温度, 管道壁厚, 约束条件的影响机制进行模拟计算和分析。结果表明: 管道一次应力随着设计压力的升高而增大, 随着管道壁厚的增加而减小; 二次应力随着管道运行温度与环境温度温差的减小而减小, 随管道壁厚的增大而减小; 设置约束可以有效减小位移和一次应力, 但固定约束会使二次应力增加, 承重约束对减小管道位移作用较小。在设计中, 管道一次应力较大, 可以采用增设15个导向约束, 并合理布置约束位置的方法进行优化, 放空管道的最大一次应力降低10.8%左右, 符合安全要求。
Abstract:
In order to ensure the safe operation of the vented pipeline reconstructed in a gas gathering station, the pipeline stress optimization study of its design scheme was carried out. CAESAR Ⅱ was used to simulate and analyze the design pressure, operating temperature, wall thickness, and constraints of the pipeline. The results show that the primary stress of the pipeline increases with the increase of the design pressure and decreases with the increase of the wall thickness of the pipeline; the secondary stress decreases with the decrease of the temperature difference between the pipeline operating temperature and the ambient temperature, and decreases with the pipeline wall thickness decreases with increasing thickness; setting constraints can effectively reduce displacement and primary stress, but fixed constraints will increase secondary stress, and load constraints have less effect on reducing pipeline displacement. In the design, the primary stress of the pipeline is large. It can be optimized by adding 15 guidance constraints and arranging the constraint positions reasonably. The maximum primary stress of the vented pipeline is reduced by about 10.8%, which meets the safety requirements.
