- 摘要:
- 苏丹港红海终端现共有8座7万m3浮顶罐,其中1～5号、6号、7号和8号罐分别于不同时期先后建成。文章就外方设计先建成的1～5号罐与江汉设计院设计的6号、7号和8号罐的设计进行了对比,指出采用“一次密封+二次密封”的双重密封型式,其密封效果优于原来的“一次密封+挡雨板”密封型式。同时考虑到制造施工方面的难度,建议在大型储罐设计中以不设清扫孔为宜。文中还将API650-1998标准与国内对应标准SH3046-1992进行了对比,提出计算大型储罐罐壁时采用API650-1998标准比SH3046-1992标准更经济合理。在罐壁和罐底排板时,采用宽板幅的罐壁板和底板可减少现场焊接工作量。
There are 8 floating roof oil tanks at Red Sea terminal of Sudan Harbor each has the storage capacity of 7×104 m3. The design contrasts between No.1～5 tanks which were designed and built earlier by foreign contractor and No.6～8 tanks which were designed by Jianghan Design Institute later is made. The results show that the effectiveness of the double seal form of ″primary seal + secondary seal″ used in No.6～8 tanks is much better than the seal form of ″primary seal + rainproof board″ used in No.1～5 tanks. Considering the difficulties of manufacture and construction the proposal that cleaning hole is unsuitable to make in a large scale tank is provided. It is pointed that the adoption of standard API 650-1998 for large scale tank wall calculation is more reasonable than that of domestic corresponding standard SH3046 and utilization of wider wall plates and bottom plates can significantly reduce field welding workload.2005,2(2): 42-45 收稿日期：2004-10-12分类号：TE972作者简介：武林静(1973-),女,河南人,工程师,1994年毕业于西南石油学院机械设计与制造专业,一直从事压力容器、大型储罐等非标设备的设计工作.参考文献：
