When defining the volume of a pressure vessel as ≥0.03 m3, is this to exclude the volume of the material filled inside it?
Under normal circumstances, the volume of a pressure vessel refers to the total internal volume of the vessel, including the volume of the material contained within it. Therefore, to meet the volume requirement of ≥0.03 m3, all the space inside the container must be taken into account, including the space occupied by the filler. .
Fillers do not belong to the category of “permanent connections””
Permanent connection: refers to the welding method
Simply put, it’s something that exists in the design.
This volume isn’t something you need to worry about; the design team will provide professional advice.
There should be no need for a deduction; it depends on the design specifications
The volume that can be replaced will not be deducted.
