Equipment with a design pressure of 0.3 Mpa and an operating pressure at atmospheric level is it considered a pressure vessel?
Thread Content
As shown in the figure, is the atmospheric pressure vessel determined based on the operating pressure or the design pressure?
I’m reaching out to all you guys for help; I’m a bit stuck. According to the definitions, the design pressure is required to be below 0.1 MPa
Not only the pressure, but also the medium needs to be considered. It cannot be judged solely based on pressure.
Yes, it also depends on the medium. Another factor is to consider the actual maximum operating temperature
You need to first understand the definition of pressure vessels; then you’ll realize that it’s not just about pressure, but also about the medium, the volume, and the boiling point of the medium
How can we determine whether this container is a pressure vessel and whether it is open?
Common containers are determined based on the operating pressure.
Regarding work pressure, values below 0.1 MPa are not within the scope of regulation; all three conditions must be met.
Whether it falls under regulatory oversight depends on the working pressure; whether it is all governed by GB150 and NB/T47003.1 depends on the design pressure. Of course, other conditions also need to be met.
Use the fixed volume gauge to check the operating pressure, and use GB150 to check the design pressure
It does not fall under the category of pressure vessels; pressure vessels require a pressure level of more than 0.1 MPa. Do not refer to GB150 – the requirement in that standard that the design pressure should be no less than 0.1 MPa is merely a constraint applied to the scope of that standard, and it has nothing to do with whether something is considered a pressure vessel or not
