How are low pressure, medium pressure, high pressure, and vacuum defined in pressure vessels?
1. Low pressure (code L): 0.1MPa ≤ P < 1.6MPa 2. Medium pressure (code M): 1.6MPa ≤ P < 10MPa 3. High pressure (code H): 10MPa ≤ P < 100MPa 4. Ultra-high pressure (code U): P ≥ 100MPa 5. Vacuum vessel: A vessel in which the pressure of the medium inside is lower than the ambient atmospheric pressure, i.e., it operates under vacuum conditions. 6. Atmospheric pressure vessel: A vessel that is directly connected to the ambient atmosphere or operates at a gauge pressure of 0; vessels with a design pressure ranging from greater than -0.02MPa to less than 0.1MPa are considered atmospheric pressure vessels

There’s a test tomorrow; values below 0.1 MPa aren’t considered vacuum, right?
How are the data for vacuum vessels defined?
It is determined based on the level of pressure. 1. Low pressure (code L): 0.1MPa ≤ P < 1.6MPa 2. Medium pressure (code M): 1.6MPa ≤ P < 10MPa 3. High pressure (code H): 10MPa ≤ P < 100MPa 4. Ultra-high pressure (code U): P ≥ 100MPa 5. Vacuum vessel: A vessel in which the pressure of the medium inside is lower than the ambient atmospheric pressure, i.e., it operates under vacuum conditions. 6.
