自1979年末,因焊接缺陷等原因,吉林某地液化气球形容器发生重大恶性爆炸事故以来,我国的容器制造、使用、管理和检验水平已有很大提高,但开裂的现象仍时有发生。这里介绍一起因容器壳板材料不良,球罐在水压试验中开裂的事故。一、壳板材料及加工情况球罐名义容积为200m~3,壳板厚24mm,设计压力1 6kgf/cm~2,常压下使用,按J B
Since the end of 1979, due to welding defects and other reasons, a serious explosion of liquefied gas spherical vessel occurred in Jilin Province. The level of manufacture, use, management and inspection of containers in our country has been greatly improved, but the phenomenon of cracking still occurs frequently. Here is a case of container shell due to poor material, spherical tank cracking in the hydraulic test accident. First, the shell material and processing conditions The nominal volume of the spherical tank is 200m ~ 3, shell thickness 24mm, the design pressure of 1 6kgf / cm ~ 2, atmospheric pressure, press J B
