我们常见的压力钢瓶有两种:一种是压缩气钢瓶,另一种是液化气钢瓶。前者钢瓶内压力比较高,其中常用的是150kg/cm~2,也有200、300kg/cm~2等级的钢瓶。如氧气、氢气、氮气、甲烷、惰性气体钢瓶等,这类压力钢瓶都有相应的耐压强度。后者钢瓶内压力较低,根据充装的介质不同,设计压力等级也不同,如液化丁烷钢瓶为10kg/cm~2,液氯钢瓶为20kg/cm~2,液氨钢瓶为30kg/cm~2,光气钢瓶为50kg/cm~2,这些钢瓶相对于前者耐压强度较低。
We have two common pressure cylinders: one is a compressed gas cylinder, the other is a liquefied gas cylinder. The former cylinder pressure is relatively high, which is commonly used is 150kg / cm ~ 2, there are 200,300 kg / cm ~ 2 cylinder. Such as oxygen, hydrogen, nitrogen, methane, inert gas cylinders, such pressure cylinders have the corresponding compressive strength. The latter cylinder pressure is low, according to the filling of different media, design pressure levels are also different, such as liquefied butane cylinders 10kg / cm ~ 2, liquid chlorine cylinder 20kg / cm ~ 2, liquid ammonia cylinder 30kg / cm ~ 2, phosgene cylinder 50kg / cm ~ 2, these cylinders relative to the former compressive strength is lower.
