| 摘 要： | GB150-1998规范根据我国多年来的使用经验和习惯,把低温压力容器的温度界线定为≤- 20 ℃,而ASME规范是根据材料种类及性能、材料热处理状态、材料厚度及应力状态,通过计算确定允许的最低设计金属温度(MDMT),若容器的使用温度低于允许的MDMT,则属低温范围,要求进行冲击试验。二者有着明显的区别。

| Abstract: | is setlled as the low temperature demarcation for a vessel in GB 150-1998 based on the practical experience and custom in China. But in ASME code, the allowable minimum design metal temperature (MDMT)is settled based on the sort and property of material, the heat treatment state of material, material thickness and its stress state. If the applied temprature is lower than the allowable MDMT, which means in low temperature scope and needs an impact test. There are obvious difference between these two standards. |
