Technical Field

[0001] The utility model relates to the technical field of pressure vessels, in particular to a low-temperature storage tank pressure vessel. Background Art

[0002] Pressure vessels refer to closed equipment that contains gas or liquid and bears a certain pressure. The scope is defined as fixed containers and mobile containers for gases with a maximum working pressure greater than or equal to 0.1MPa (gauge pressure) and a pressure-volume product greater than or equal to 2.5MPa·L, liquefied gases and liquids with a maximum working temperature higher than or equal to the standard boiling point; gas cylinders containing gases with a nominal working pressure greater than or equal to 0.2MPa (gauge pressure) and a pressure-volume product greater than or equal to 1.0MPa·L, liquefied gases and liquids with a standard boiling point equal to or lower than 60°C; oxygen chambers, etc.

[0003] Storage tanks are generally used to store gaseous or liquid chemicals.
