Disclosed is a membrane for a cryogenic fluid storage tank. The membrane for a cryogenic fluid storage tank of the present invention includes: a plurality of transverse corrugations formed on a metal membrane sheet in a transverse direction; and a plurality of longitudinal corrugations formed thereon in a longitudinal direction, wherein all the transverse and longitudinal corrugations are finished on an inner side of the membrane sheet so that an edge of the membrane sheet is provided in a flat shape. Reinforcing corrugations having a width and a height smaller than that of the transverse and longitudinal corrugations are formed in the flat edge of the membrane sheet. Therefore, the stress can be prevented from being concentrated around a flat welding line of the edge of the membrane.

    극저온 유체 저장탱크의 멤브레인이 개시된다. 본 발명은 금속 멤브레인 시트 상에 횡방향으로 형성되는 다수의 횡방향 코러게이션 및 종방향으로 형성되는 다수의 종방향 코러게이션을 포함하는 극저온 유체저장탱크의 멤브레인에 있어서, 상기 횡방향 및 종방향 코러게이션은 멤브레인 시트의 내측에서 모두 마감이 이루어져, 멤브레인 시트의 가장자리가 플랫한 형태로 마련되고, 멤브레인 시트의 플랫한 가장자리에 상기 횡방향 및 종방향 코러게이션보다 작은 폭과 높이를 가지는 보강 코러게이션이 형성됨으로써, 멤브레인 가장자리의 플랫한 용접라인 주위에 응력이 집중되는 것을 완화시킨다.
