Do containers that are not of a special type refer to atmospheric-pressure containers?

How to tell the difference? {:1_90:}
Those that comply with NB/T 47003.1 are atmospheric pressure vessels, while those that comply with GB150 but are not subject to inspection under the Fixed Pressure Vessels Regulations are non-classified vessels
Scope of application of GB150 \"Steel Pressure Vessels\": 0.1~35MPa; -0.1~-0.02MPa
No. Those with a design pressure of P≥0.1MPa or a vacuum level of ≥0.02MPa fall under the category of pressure vessels as defined in GB150. Those with a design pressure of P＜0.1MPa or a vacuum level of ＜0.02MPa are considered normal-pressure vessels. Additionally, there may be containers that are not covered by either GB150 or NB47003, such as those used in direct flame heating applications or within nuclear energy installations.
It is best to make a detailed judgment based on the container’s purpose, the medium used, and the conditions of its use. Each standard has its own scope of application; it cannot be simply assumed that a container belongs to the category of atmospheric pressure containers just because it does not fit into another category.
Category is related to pressure, but not in every case; a container filled with water at a temperature of no more than 100 degrees will not experience any pressure regardless of its height. Let’s take a look at the tolerance specifications and 150 instead!
The classification of containers is determined according to the (new container regulations). Atmospheric pressure vessels are definitely not classified; pressure vessels may be classified or fall outside any classification. The 4th floor provides a more comprehensive explanation; judgments should be made according to its corresponding standards.
Reply to 1# HaiChuanXiaoDangJia: The answer to this question cannot be explained in just a few words. I’m not sure what you want to know; are you involved in the design of pressure vessels?
