三、液氯钢瓶的爆炸 及原因分析 经调查,几年来在钢瓶的使用中发生过一些事故,其中有因焊缝腐蚀造成漏气的(图3); 也有保护罩被碰坏的(图4);有的发生了明显的永久变形(图5)。产生永久变形的钢瓶与爆破试验时达到屈服压力后的钢瓶(图6)比较,外形是近似的。另外,有些钢瓶在使用过 Third, the explosion of liquid chlorine cylinders and analysis of the cause After investigation, in the past few years in the use of the cylinder there have been some accidents, including leakage due to corrosion of the weld (Figure 3); also the protective cover was damaged (Figure 4 ); Some obvious permanent deformation occurred (Figure 5). Cylinders that produce permanent deformation are approximately similar in shape to cylinders that have reached yield pressure during the burst test (Figure 6). In addition, some cylinders are used
