球罐在石油、化工、冶金、城建等部门已得到了比较广泛的应用。随着各种球罐建造量逐年增加,由各种原因引起的爆炸破裂事故也有所增加。球罐一旦发生爆炸破裂事故,后果严重,损失极大。因此,对球罐破裂原因的分析越来越引起人们的关注。我厂一台400m~3球罐在水压试验过程中曾发生破裂,本文仅对该球罐破裂的经过及原因作一初步分析。一、设计条件和原始数据几何容积:408m~3;设计压力:22kgf/cm~2(表);
Spherical tank in the petroleum, chemical, metallurgy, urban construction and other departments have been more widely used. With the construction of various types of spherical tanks increasing year by year, explosions and fractures caused by various reasons have also increased. In the event of an explosion and explosion of a spherical tank, the consequences will be serious and the loss will be enormous. Therefore, the analysis of the causes of the rupture of the spherical tank attracts more and more attention. I plant a 400m ~ 3 spherical tank in the hydrostatic test occurred in the rupture, this article only on the rupture of the tank and the reasons for a preliminary analysis. First, the design conditions and the geometric data of the original data: 408m ~ 3; design pressure: 22kgf / cm ~ 2 (table);
