大型原油储罐构件预制方法

Method on Units Prefabrication for Large Crude Oil Tanks

对构件进行预制可以提高施工效率、缩短工期,是目前大型原油储罐建造的常用方法。对照阿布扎比原油管道项目16×10~4m^3浮顶储罐建造案例,以大型原油储罐的构件预制过程为基础,对清扫孔和有罐嘴的罐壁板的预制方法、检验步骤和热处理过程进行详细分析,大型储罐底板、壁板等主要构件需要按照合理的工作流程进行预制,并进行适当的热处理和检测,以提高制造精度。采用构件预制方法,可以保证大型浮顶储罐的构件预制深度,提高大型储罐的建造效率,节约时间成本和施工成本。

PreFabrication of units is one oFthe most commonly used construction method for large storage tanks because of high efficiency and short construction duration. The key processes of the crude oil tank units prefabrication were discussed based on the construction of 16 × 10^4 m3 tank in Abu Dhabi pipeline main terminal station. The prefabrication, testing procedure and heat-treating process of cleanout door and shell plate shall Follow the normal procedures with high accuracy, before the PWHT and inspection. The optimized procedures can ensure the units prefabrication quality, provide comprehensive and detailed technique instruction, improve the construction efficiency, and shorten the time costs and construction COSTS.
