About equipment nameplate media printing
Thread Content
Our company produces vertical cryogenic liquid storage tanks (high vacuum multi-layer insulation, implementing standards GB/T150, TSG 21, GB/T18442), with a volume of 4.99 cubic meters, a design pressure of 1.68MPa, a working pressure of 1.6MPa, a design temperature of -196℃, a working temperature of 50℃, and filling media of liquid nitrogen, liquid oxygen, and liquid argon (the design drawing is a set, and the filling medium is liquid oxygen, nitrogen, and argon). When our company obtains the special equipment supervision and inspection certificate after the manufacturing is completed, can all the filling media in the name brand content be printed with liquid nitrogen, liquid oxygen, and liquid argon? If there is no basis for it? Now the local supervisory inspection agency does not agree to use the three media. But other companies do it this way.
With such a big platform, no one makes this kind of storage tank?
The nameplate should be consistent with the design drawing.
It's written like this on my drawing. Can famous brands also be written like this?
Generally, it is done according to the drawings, but the equipment is subject to supervisory inspection. If others do not agree, you can only follow other people's instructions. If you don't listen to them, your equipment will not leave the factory. To choose one, you choose the medium that is most important for classifying the container.
The physical properties of these three media are different. How come the working temperatures are the same? And the working temperature is 50℃?
Low-temperature storage tank, double-layer insulated, 50 is the outer shell
The saturated vapor pressures at the corresponding temperatures of the three media are different, and the operating conditions are also different. It seems inappropriate to use one picture.
