These parameters can be used to design a product and determine its category. For your reference: Name: Heat exchanger; Heat exchange area: 5 m3; Shell side dimension: DN325; Tube side dimension: L=1000; Fluids: Tube side – tail water; Shell side – 5°C cold water; Operating temperature: Tube side – 80°C; Shell side – 5°C; Operating pressure: Tube side – 0.09 MPa; Shell side – 0.15 MPa
Is there a gas phase space? If it is ordinary water-to-water heat exchange, it does not fall into this category
Categories can be determined, but a product cannot be designed
Based on the data provided by the poster, to design a heat exchanger, this needs to be considered from two perspectives. If such a request is made to the equipment department in an engineering company or design firm for a detailed design, it’s simply ridiculous. First, such conditions cannot be applied in the processing room; second, the equipment will not accept such conditions. If it is proposed by an individual owner, private manufacturers may be able to proceed after communicating with the owner regarding the relevant terms.
It’s not classified as such; the temperature hasn’t exceeded the boiling point, and both the tube side and the shell side are in a liquid state
Is the determination of the heat exchange tube based on the design pressure of the shell side or that of the tube side?
It falls outside the scope of regulatory control and is not classified. (According to the given conditions)

Determine separately which one is higher, and follow that one
Then may I ask, should my product not be classified in that category?
