中小型圆柱形钢油罐直径和高度的计算方法

Selection of Diameter and Height of Medium and Small Cylindrical Steel Tank,OGST

从实际计算出发,将等壁厚油罐和变壁厚油罐统一考虑,得到了最省材料的中小型油罐的高度确定方法。计算表明,油罐的最优高度不但与钢材种类、焊接水平、顶底厚度之和有关,而且还与所设计油罐的圈板数(或圈板高度)、最小壁厚、液面蒸气压等有关。用原有方法确定油罐高度有些偏大。对公称容积相同但计算容积不同的油罐,其设计高度应有所区别。

Based on the actual design of medium and small cylindrical steel tank,a method to calculate the height of the tank has been found. At the height the steel to be used is least. The method can be applied to uniform and variable shell thickness of the tank. It was found that the height is dependent not only on steel, welded seam and the thickness of the shell and bottom,but also on height of wall-plate,minimum shell thickness and vapour pressure. The height calculated by the old method is more than that by the paper. The height of different actual volume tank at uniform nominal volume should be a little different.
