Abstract : The defect s possibly bring about in t ruck and railway tankers during their fabrication
and using andthe relative nondest ructive testing methods were reviewed , including radiographic
testing , ult rasonic testing ,ic particle testing , dye rant testing , ic flux leakage
testing , acoustic emission testing ic memory testing. The characteristics of the methods
were also int roduced.

《压力容器安全技术监察规程》将汽车罐车(液化气体运输(半挂) 车、低温液体运输(半挂) 车) 、
铁路罐车(介质为液化气体和低温液体) 和罐式集装箱(介质为液化气体和低温液体) 统称为移动式压力
容器,有常温型、低温型和深冷型。它们广泛用于石油和化学、航天航空、电子与机械、食品与烟草和医
疗等领域,特别是近几年来,我国加快城市燃气化的步伐和加大环境保护的力度,对该类容器的需求
