Abstract
(EN)
The present invention relates to a membrane-type insulating system for a cargo tank and a liquefied gas fuel container of a cryogenic liquefied gas carrier, the system having a corrugation-finishing membrane, which is made from an Invar material, welded to a secondary membrane connecting part or a primary membrane connecting part in order to seal corrugations at corner parts when a primary membrane and/or a secondary membrane is made from a SUS material having the corrugations, so that a separate angle piece for connecting the corrugations on the adjacent wall surfaces of the corner parts is unnecessary, and thus workability is improved and manufacturing costs can be reduced.
(FR)
La présente invention concerne un système d'isolation de type à membrane destiné à une citerne à marchandise et un conteneur de combustible liquéfié gazeux d'un transporteur de gaz cryogénique liquéfié, le système ayant une membrane de finition cannelée, qui est constituée d'un matériau Invar, soudée à une partie de raccordement de membrane secondaire ou à une partie de raccordement de membrane primaire afin d'isoler des cannelures au niveau de parties angles lorsqu'une membrane primaire et/ou une membrane secondaire sont constituées d'un matériau SUS présentant les cannelures, de sorte qu'une partie angle distincte destinée à relier les cannelures sur les surfaces de paroi adjacentes des parties angles n'estt pas nécessaire, et ainsi l'aptitude au façonnage est améliorée et les coûts de fabrication peuvent être réduits.

본 발명은 극저온 액화가스 운반선의 화물창 및 액화가스 연료용기의 멤브레인형 단열시스템에 관한 것으로, 1차 멤브레인과 2차 멤브레인 중 적어도 어느 하나 이상이 주름부를 갖는 서스(SUS) 재질로 구성되는 경우, 코너부에서 주름부를 밀봉 처리하기 위하여 2차 멤브레인 연결부 또는 1차 멤브레인 연결부에 인바 재질의 주름부 마감용 멤브레인을 용접함으로써, 코너부의 인접한 벽면에서 주름부를 연결하기 위하여 별도의 앵글 피스(angle piece)가 불필요하게 되어 작업성을 향상시키고 제조비용을 절감할 수 있다.
