大型外浮顶罐加顶盖问题探讨

ADDING A HEAD ON LARGE EXTERNAL FLOATING-ROOF TANKS

大型外浮顶罐由于浮顶暴露在大气中,受外界自然现象的影响很大,从而引发许多不安全因素并带来较大的经济损失。借鉴国外经验,在外浮顶油罐加上铝合金穹顶,可以带来一系列好处,而且便于实施。敞口的大型外浮顶罐将逐步被代替。

As the large external floating-roof tank is exposed to atmosphere, it is subject to the great impact of natural conditions which may bring in numerous unsafe factors and lead to greater economic losses. The installation of an additional vault head on the external floating-roof tank, which is easy in implementation, offers a number of advantages. Therefore, the open large external floating-roof tanks will gradually be replaced by this design.
