Pressure vessel at normal temperature and pressure
Thread Content
What is the typical temperature for pressure vessels under normal temperature and pressure conditions? What is the pressure? If the operating temperature is at room temperature, then what should the design temperature be? Should we take into account the difference in temperatures between winter and summer?
At normal temperature and pressure, it can no longer be considered a pressure vessel; it can only be called a container.
The operating temperature is at room temperature, and the design temperature should take into account the highest and lowest monthly average temperatures in the local area.
Room temperature and pressure should refer to the ambient temperature! The design temperature and pressure allow for operational flexibility; there are no fixed values!
The highest and lowest metal temperatures should take into account both the ambient temperature and the medium temperature, right?
It mainly depends on the ambient temperature......
Low-temperature and low-stress operating conditions can be considered; otherwise it cannot be used
According to standards, room temperature generally refers to around 20°C; in reality, however, it denotes a range of -20 to 50°C. Atmospheric pressure refers to one atmosphere.
Atmospheric pressure is easy to understand; it refers to a gauge pressure of zero. Room temperature generally refers to a temperature of around 20°C, but considering that the ambient temperature is surely below zero degrees, the temperature of the medium usually does not drop below zero degrees. Therefore, corresponding thermal insulation requirements should be specified when designing the container.
The normal temperature should be the same as the ambient temperature; normal pressure refers to one atmosphere, that is, a gauge pressure of 0 and an absolute pressure of 0.1 MPA.
