2011年8月某汽车运输公司一辆装载环氧乙烷的罐车在EO充装站充装中发生泄漏事故。当时值班人员检查发现罐体牵引盘处有液体漏出,充装站立即启动应急预案,罐内物料被抽,出事后检验人员将罐体前部保温层剥开,在罐内注入清水后,发现拖车盘上方罐体支座垫板与罐体连接处的角焊缝上有水漏出。1事故罐车参数设计压力0.8MPa,设计温度-10~20℃,材料0Cr18Ni9,简体、垫板壁厚8mm。外表面发泡保温。2缺陷形状描述
In August 2011 a tanker loaded with ethylene oxide from a motor carrier leaked at filling of the EO filling station. At that time on duty inspectors found liquid leakage at the tank traction plate, filling station immediately start the emergency plan, the tank material was pumping, after the accident inspector will be able to peel the front of the tank insulation in the tank into the water and found that There is water leakage on the fillet weld at the junction of the tank support plate and tank at the top of the trailer plate. 1 accident tanker design pressure 0.8MPa, design temperature -10 ~ 20 ℃, material 0Cr18Ni9, simplified, plate thickness of 8mm. Foam insulation on the outer surface. 2 defect shape description
