摘　　要：以山东某些汽车罐车使用厂家已产生缺陷的几台汽车罐车为研究对象,对其实际运输过程中焊缝开裂、筒体裂纹、防波板处裂缝等缺陷以及对事故处理不当造成的缺陷进行了分析,提出了相应的解决办法。分析结果表明,缺陷产生的主要原因是在制造过程中未能按设计资料进行加工制造。对于罐车的缺陷修复,应在设计者提出具体修理方案并办理相关手续后,由有资质的维修单位按相关标准和法规的要求进行,修复后需经检验机构检验合格方可使用。To a great extent, traffic accidents of liquefied gas tankers were caused by the defects inside the tankers themselves. It is of great significance to analyze what caused the defects and how to put forward the corresponding prevention measures, to reduce accident risk. The research objects were some defective liquefied gas tankers in propylene factories in Shandong. The defects in actual transportation process containing weld joints defects, crack, anti-wave plates and the defects caused by the accident misconduct were analyzed, and the corresponding solutions were put forward on the basis of the literature analysis. The results show that the main causes of the defects are that the manufacture and processing do not correspond with design data. The defects repair of the liquefied gas tankers should be performed by qualified service units after specific re- pair plan and relevant formalities are put forward. The repaired liquefied gas tanker should be inspected and qualified by the inspection organizations.
