What does fixed roof mean? What other types are there besides fixed roofs?
Relative to the floating roof. . . . . .
Fixed-roof storage tanks and floating-roof storage tanks are both vertical tanks at atmospheric pressure, and their selection is generally determined based on the flash point of the material.
A fixed roof means that the roof of the storage tank cannot move; it is fixed in place. There are also internal floating roof and arch top tanks.
The difference between fixed-roof storage tanks and floating-roof storage tanks is that the roof of the former does not move up and down as the material moves in and out, while that of the latter does move up and down； Floating roof tanks are further divided into internal floating roofs and external floating roofs
When a fixed-roof storage tank is used to store gas, does the pressure inside it change?
Are fixed-roof storage tanks used to store gases? I haven’t heard of that; are they gas cabinets?
Devices for storing gas are generally pressure vessels. It needs to be discussed separately
Gas is stored in a floating roof, that is, a gas holder, which is used for recovering the released gas. The gas pressure inside the gas holder remains essentially constant, with the compressor being used to increase the pressure.
Is it true that fixed roofs are generally only suitable for storing liquids, while floating roofs are only suitable for storing gases?
