Issues regarding the calculation of wall thickness for vacuum pressure vessels.
Thread Content
For a circular tank with a design pressure of -0.1 to 0.6 MPa, a diameter of 500 and a height of 950, how should the wall thickness be calculated when both negative and positive pressures are present? Could you please explain in detail how to calculate it? Thank you
I used SW6 to calculate that the wall thickness is 4 mm, but it seems a bit unreliable to me. Could you please help check whether I entered the wrong data?
Corrosion margin, material type, and negative deviations in material thickness all need to be taken into account. For 345R, since corrosion margin is not considered, it’s not a big issue; I recommend consulting someone who specializes in equipment.
Material 30408, corrosion margin 1.5
Then you need to calculate it again.
A thickness of 6 mm is sufficient. 4m is a bit too thin; this is based on experience from those who work with equipment.
