摘要
GB15 0标准中规定 :“低温容器用钢的冲击试验温度应低于或等于壳体或其受压元件的最低设计温度”。当容器的最低设计温度为 - 196℃时 ,实际的低温冲击试验温度无法实现低于或等于- 196℃的要求。本文经分析论证了多项影响因素 ,提出了对GB15
It is stipulated in GB150 Standard 'The cryogenic impact test temperature for the steel of the cryogenic vessel shall be lower than or equal to the lowest design temperature of its shell or pressure components'.When the lowest design temperature of the vessel is -196℃,it is impossible for the actual cryogenic impact test temperature to be lower than or equal to -196℃.After a number of factors have been analyzed and expounded,the revision proposal for the stipulation of the cryogenic impact test temperature in GB150 Standard is presented.
