Help: There is a /F.V. indicated for the design pressure on the pressure vessel design drawings.
Thread Content
On the design drawings of pressure vessels, there is a value denoted as F.V. associated with the design pressure. What does F.V. mean? For example, on the design drawings, the design pressure is indicated as 2/F.V. MPa – what is this F.V.? I would appreciate it if someone could explain it to me!

F.V. indicates that the design pressure is in a vacuum state, while 2/F.V. means there are 2 design conditions: one with a design pressure of 2.0 Mpa and the other in a vacuum state:handshake :handshake
The answer above is correct; FV refers to the full vacuum design condition (which is an abbreviation for full vacuum), with a design pressure of -0.1 MPa (gauge pressure). This post was last edited by c_m_1979 on 2008-1-10 at 10:00.]

FV stands for complete vacuum, and -0.1 MPa is usually adopted in calculations. However, it’s not true that complete vacuum always equals -0.1 MPa; this value depends on the atmospheric pressure in the area where the equipment is located. In high-altitude regions, the value for complete vacuum might be -0.08 MPa.
FV denotes full vacuum; it is specified as -0.1 MPa in the design
I’ve seen this situation for the first time; I learned from it
FV is in a fully vacuum state, with a design pressure of -0.1 MPa
