A corner insulation wall of a membrane type storage tank according to the present invention comprises: an insulation layer wherein the inside space of a liquefied natural gas (LNG) storage tank is insulated from the outside, having a bent shape to be arranged in a corner of LNG storage tank; a coupling layer of a first sealed wall coupled along with the bent corner of the insulation layer; and a coupling layer of a second sealed wall spaced from the coupling layer of the first sealed wall and coupled to the insulation layer. According to the present invention, the membrane type storage tank has the second sealed wall made of stainless steel, is able to endure a thermal deformation, and can be easily coupled to an insulation wall.
본 발명에 따른 멤브레인형 저장탱크의 코너부 단열벽은, 액화천연가스 저장탱크의 내부 공간을 외부와 단열시키며, 액화천연가스 저장탱크의 코너에 마련되도록 절곡된 형태를 갖는 단열층, 상기 단열층의 절곡된 모서리를 따라 결합되는 제1 밀봉벽 결합층 및 상기 제1 밀봉벽 결합층과 이격되어 상기 단열층 상에 결합되는 제2 밀봉벽 결합층을 포함함으로써, 본 발명에 의하면, 2차 밀봉벽이 스테인리스 강으로 형성되면서도, 열변형에 대응할 수 있고, 단열벽과의 결합이 용이하도록 구성되는 멤브레인형 저장탱크를 구현할 수 있다..
