Does a vacuum heating furnace belong to pressure vessels?

Thread Content

Why are vacuum heating furnaces regulated as pressure vessels? Is it because the medium inside the tube side of the vacuum heating furnace is a pressurized oil-water mixture?

There are many disputes regarding the management of heating furnaces. I’m not sure what level of vacuum you are referring to; as long as the pressure inside the enclosed housing is less than -0.02 MPa, the housing should be designed for a pressure rating of 150. But it is not necessary to classify them, and they are not subject to tolerance regulation oversight
