摘要
非圆形截面容器设计 ,ASME和GB150中有明确的规定。燕化公司化工一厂苯乙烯装置 30 0单元脱氢尾气冷却器EA - 30 9壳程入口段为长圆形截面容器。由于结构特殊 ,规范不适用 ,在重新设计时 ,针对其结构特征 ,进行了受力分析 ,推导出符合实际的应力计算公式。
The design of noncircular section vessels is specified in ASME and GB150. EA309 is the dehydrogenating tail gas cooler in unit 300 of styrene workshop in chemical works No.1.which inlet section is circular section vessel. Because of its special structure, formulae in former specifications can not be used. During redesigning, force analysis and theory deduction is redone according to the structure of EA309. Practical stress formulae are obtained.
