由于最近几年石油开采量的不断提高,相应地引起石油炼厂基本建设规模的巨大增长,为了缩短炼厂建设期限,适应石油工业发展的要求,必须继续不断地改进自己的施工方法和采用先进的(快速)施工方法进行工艺装置的施工。立式圆柱形钢质油罐的建造,几年来各施工单位曾大批地采用了倒装法及卷装法,代替了旧的正装法,并取得了比较成熟的经验。经验证明,采用倒装法及卷装法安装油罐有很多优点:缩短了安装期,例如一具容积400米~3油罐用正装法需14天,而倒装法仅用10天,提高了焊接质量,特别突出的是卷装法可以采用
Due to the continuous increase of petroleum exploitation in recent years, a corresponding huge increase in the scale of capital construction of petroleum refinery, in order to shorten the construction period of the refinery and meet the requirements of the development of the oil industry, we must continue to improve our own construction methods and adopt advanced (Rapid) construction method for the construction of process equipment. Vertical cylindrical steel tank construction, the past few years the construction units have used a large number of flip and roll method, instead of the old formal method, and has gained more experience. Experience has shown that the use of flip and roll installation of the tank has many advantages: shorten the installation period, for example, a capacity of 400 m ~ 3 tank with the law to take 14 days, and flip-up only 10 days, increased The quality of welding, with particular emphasis on the package method can be used
