各位海友，常压罐压力一般为1.2Kpa ，那么常压跟标准大气压语言上怎么理解，一个1.2Kpa 一个101.3Kpa

常压是指的一个标准大气压，而一个标准大气压的压力是101.3kPa，而工程上常将一个标准定为100kPa，所以一般常压设备指的就是操作压力1点多千帕，这个值与所处的地域的大气压力有一定的管线；而标准大气压指的是是在标准大气条件下海平面的气压，是一个定值101.3kPa

本帖最后由广州起义于 2019-11-28 14:59 编辑 101.3KPa指的是绝压，常压罐1.2KPa是表压。是这意思吧。常压容器压力规定，设计压力大于-0.02MPa,小于0.1MPa，是指表压。

常压是当地的大气压，标准大气压是101.325kpa
