Annular metal shielding device for low-temperature film shielding device

The utility model discloses an annular metal shielding device for a low-temperature film shielding device, which belongs to the technical field of liquefied natural gas (LNG) low-temperature storage devices and comprises at least one low-temperature shielding structure arranged in a sequence form or a staggered form. The low-temperature shielding structure is made of at least one standard template, and the standard template is a metal sheet with a continuous annular corrugated convex structure. According to the utility model, the annular convex film shielding structure is used for replacing the existing film, the dependence on the special equipment film is reduced, the batch production is realized, the working hours of glue bonding, solidification waiting, construction drying and the like on the construction site are reduced, the working hours are changed into skilled welding work, the construction amount is reduced, and the construction period is shortened. 本实用新型公开了一种用于低温薄膜屏蔽装置的环形金属屏蔽装置，属于液化天然气(LNG)低温储存装置技术领
