Although the medium is water, a gas phase space is taken into account, which is why it is classified as category 2
Depending on the conditions of the medium, it falls outside the scope of dimensional tolerances and therefore should not be classified.
If there is no gas phase space, it does not fall into this category; the maximum operating temperature of the medium is not higher than or equal to its standard boiling point.
Judging from the data sheet, it is an external container.
In accordance with the Provisions on Safety Supervision of Pressure Vessels, medium-pressure vessels, low-pressure vessels handling highly toxic media, low-pressure reactors and storage vessels containing flammable or toxic media, as well as low-pressure waste heat boilers with an inner diameter of less than 1 meter – any vessel that falls under one of these categories is classified as a Class II vessel. I’m not entirely sure whether what you’ve sent is specifically related to the gas phase space
Based on the data table, it should be a non-classified container.
The medium is water; heat exchangers generally do not have a gas phase space, and the operating temperature is below the standard boiling point, so they should not be classified as special containers
The medium is water; although the design pressure is 2.5 MPa, the operating temperature does not reach the standard boiling point, so it should not be classified
