摘　　要：本文结合工程设计、针对球罐配管简化为薄壁圆管组成的空间钢架结构，按照管道布置和支持的实际情况，计算了球罐配管系的位移、内力和应力以及球罐向心接管斜法兰与焊缝强度、弯矩和轴向力，分析了球罐向心接管法兰面倾斜７．５°对位移、应力、弯矩、轴向力的影响，并提出设计建议供工程设计参考。Abstract In this paper,the authors built up a spatial steel tubes structure model and applied it to represent the pipeline system which connecting with six spherical tanks. The pipeline model is implemented into MSC/NASTRAN finite element method software calculation the pipeline system deformation and node inner-force and stress results were given out.analyses the influence of centripetal takes over oblique flanges 7 5° of spherical tank to the weld area strength、pipeline system deformation and stress.make proposal of engineering design by this paper.
