大型油罐壁板组装焊接变形的综合控制措施

Welding Deformation Controls for Large-Volume Oil Tank Wall Erection

壁板的变形控制是大型油罐质量控制的重点和难点。本文结合 10 0 0 0 m3 内浮顶油罐的工程实践 ,从预制加工、组装、焊接全过程分析壁板变形的各种现象和成因 ,针对壁板变形的不同情况提出有针对性的控制措施 。

Deformation control of the wall is of great importance and difficulty for quality control of large-volume oil tank.Based on the process of the wall preparation,erection and welding from the practice of some 10,000 m^3 oil tanks with an inner floating drum,this article analyzes the phenomena and causes of the wall deformation and puts forward the relevant controls for a variety of the wall deformation,which have already achieved reasonable effects.
