Regarding the classification of containers

According to relevant regulations, devices with an operating pressure below 1 bar are not classified as pressure vessels; however, an engineer at the company today said that it does fall under the category of pressure vessels, on the grounds that the design pressure is 1.45 bar. There was a long debate regarding this, and things became confusing. I wonder if it’s me who misunderstands or if the engineer is wrong. What the engineer meant was that since the design pressure is 1.45 bar, it falls under the scope of these regulations

Code for Fixed Pressure Vessels 1.7 Categories of Pressure Vessels: “Based on the degree of hazard, pressure vessels within the scope of application of these regulations are classified into three categories to facilitate categorized supervision and management...””

If your engineers believe that the design pressure is greater than 0.1 MPa and therefore it falls under the scope of safety regulations, then you need to learn more*.
Reply to 1# lxh313314: Your engineers are correct; it belongs to pressure vessels. However, it doesn’t fall into a specific category (your engineers didn’t insist on classifying it as such either, so what’s there to be confused about?).
It doesn’t fall into any specific category, but its manufacturing must comply with GB150 standards; it is a pressure vessel yet lacks a designated category. Nowadays, the regulations regarding pressure vessels tend to focus more on the management of such equipment.
There should be no further deliberation on this issue. Categorize by work pressure.
It falls under pressure vessels but is not regulated by the \"Regulations on Pressure Vessels\"; just give this document to the engineer so they can study it, that’s all
It falls under pressure vessels, but is not within the scope of supervision for fixed vessels
New capacity standard*: operating pressure greater than 0.1 MPa
