Is a resin column filled with liquid and under pressure considered a pressure vessel?
Thread Content
Specifically, the resin column operates at room temperature; the feed is an aqueous solution. As this solution is fed in, it fills the resin column, and then the pressure difference across the resin, provided by the pump, of approximately 0.3 mPa ensures the required flow rate. However, according to the definition of pressure vessels given in the catalog of special equipment, since the maximum operating temperature of the liquid inside this resin column is not higher than its boiling point, does this mean it does not qualify as a pressure vessel?
Elements of pressure vessels: medium (gas or liquefied gas), pressure, volume!
Pressure vessels filled with liquid that have not reached the standard boiling point do not fall under the regulations regarding fixed capacity
It is considered a pressure vessel and is not governed by the containment regulations. The original poster doesn’t have a clear understanding of what a pressure vessel is; any container that holds a pressure higher than that of the surrounding environment is considered a pressure vessel. It’s just that some of these containers pose very little risk in the event of an accident, which is why there are no mandatory requirements or relevant legal regulations for such containers.
Thank you! I see; I was mistaken before. It turns out that pressure vessels are not the same as those specified in the pressure vessel regulations
So far, the clearest description of the definition of pressure vessels that I have seen.
