The inner tube is at atmospheric pressure; is the heat transfer oil in the jacketed tube considered a pressure pipeline?

Dear marine industry professionals, the inner pipe contains asphalt as the medium (at atmospheric pressure), while the jacket pipe uses heat transfer oil; both the inner and outer pipes have a diameter of over 100. Does such a pipeline qualify as a pressure pipeline?
Well, nowadays all Class C media are considered pressure pipelines.
If the inner tube is at atmospheric pressure, does it still need to be classified as a pressure pipeline?
The netizen on the 1st floor replied very professionally; I learned a lot from it
How could it be at normal pressure? How does the medium flow? Is there no pump? Does it flow due to gravity?
