- 我国原油储罐正向大型化、群罐化发展。储罐变形的控制是大型储罐施工中的核心问题,而储罐壁板立缝角变形的控制是保证罐体施工质量的关键环节。为此,提出了壁板预制质量控制和壁板焊接角立缝变形控制的系列措施,使施工质量达到规范要求。
In our country, crude oil storage tanks are being developed in the form of large scale and clusters. Thereof, the control of storage tank deformation is the core of the storage tank construction. The control of angular deformation at vertical welds of large scale storage tank wall is critical for assuring the construction quality of the tank. Therefore, a series of measures controlling prefabrication quality and welding angular deformation of the tank wall are put forward and the tank construction quality satisfies the code requirement.2008,6(6): 54-55 收稿日期：2008-1-24分类号：TE972.5作者简介：王宏强（1982-），男，宁夏西吉人，助理工程师，2003 年毕业于兰州石化职业技术学院机械工程专业，现从事设备专业项目管理工作。参考文献：
