What standards are followed in the design of atmospheric pressure vessels, and how is the design pressure determined? Is non-destructive testing required for the weld?
Reference can be made to NBT 47003.1-2009 for steel welded atmospheric pressure vessels; if the operating pressure is at atmospheric pressure, I usually set the design pressure to the same value； The inspection requirements can also refer to the previous standards. If the medium height is high and the hazard level is extreme, exceeding the scope of NBT 47003.1-2009, a design pressure of 0.1 MPa shall be adopted, and the design shall be carried out in accordance with GB/T150
Agree with the second floor’s opinion; additionally, consider the minimum thickness required to account for deformation during transportation, as well as factors such as negative pressure and stiffness, and stability.
Please refer to NBT 47003.1-2009 Steel Welded Atmospheric Pressure Vessels
Design pressure: We usually fill in 0.02 MPa
wanlirn: The design pressure is set at 0.02 MPa – is this based on the design criteria for pressure vessels subjected to external pressures?
Gauge pressure: 0.02 – how can it be external pressure?
Is this value a value intended to facilitate calculations? Why isn’t it 0.03?
This pressure of 0.02 is the upper limit for the standards of atmospheric-pressure vessels; therefore, our company sets the minimum design pressure for such vessels at 0.02； Anyway, anything exceeding that falls under GB150 standards
