I humbly ask the experts: what markings should be applied to containers designed for negative pressure?
Is what the poster is referring to a vacuum container? Depending on the vacuum level, determine whether to apply the 150 standard or the normal pressure vessel standard
Negative-pressure containers are also considered pressure vessels; during design, the wall thickness is determined primarily based on the stiffness of the equipment
GB/T150-2011
It’s generally in accordance with GB150, right? The standard is specified there, isn’t it?
Check what the negative pressure is and what type of equipment it is. For storage tanks, there are the standards 50341 and 3167. If it is a container with high negative pressure, then 150 is the only option.
