Embodiment Construction
[0055] figure 1 Shown is a corrugated metal sheet 1 used to form the sealing membrane of a tank for storing cryogenic fluids such as liquefied natural gas.
[0056] The metal plate 1 comprises a first series of parallel corrugations 2, called lower corrugations, extending along the y-direction, and a second series of parallel corrugations 3, called upper corrugations, extending along the x-direction. extend. The direction x and the direction y of these series of corrugations are perpendicular. The corrugations 2, 3 protrude from the sides of the inner face of the metal plate 1 to come into contact with the fluid contained in the tank. In this case, the edges of the sheet metal 1 are parallel to the corrugations 2 , 3 . It should be noted that the terms "upper" and "lower" have relative meanings and mean that the corrugations 2, called lower corrugations, have a lower height than the corrugations 3, called upper corrugations. Furthermore, in an embodiment not shown, the co...
