Disclosed is a liquefied natural gas transfer pipe for supplying fuel of a ship engine. The transfer pipe comprises: an inner pipe for forming a flow path in which liquefied natural gas moves; a heat-insulating part for encompassing the outer peripheral surface of the inner pipe; an outer pipe for encompassing the heat-insulating part so that the inner peripheral surface thereof is spaced a predetermined interval from the outer peripheral surface of the heat-insulating part, thereby enabling an air gap to be formed; and an interval-maintaining means provided on the heat-insulating part and the outer pipe so as to separate the outer peripheral surface of the heat-insulating part and the inner peripheral surface of the outer pipe and maintain an interval therebetween, wherein the heat-insulating part has independent unit heat-insulating members, which have hollow portions and are stacked in a radial direction around the outer peripheral surface of the inner pipe, and the unit heat-insulating members, having the same diameter and being stacked in the longitudinal direction of the inner pipe, are continuously joined so that independent contact air gaps are formed between the stacked unit heat-insulating members.

    L'invention concerne un tuyau de transfert de gaz naturel liquéfié destiné à l'alimentation en carburant d'un moteur de navire. Le tuyau de transfert comprend : un tuyau interne destiné à former un trajet d'écoulement dans lequel se déplace le gaz naturel liquéfié ; une partie d'isolation thermique destinée à entourer la surface périphérique externe du tuyau interne ; un tuyau externe destiné à entourer la partie d'isolation thermique de telle sorte que sa surface périphérique interne soit espacée d'un intervalle prédéterminé de la surface périphérique externe de la partie d'isolation thermique, formant ainsi un espace d'air ; et un moyen de maintien d'intervalle disposé sur la partie d'isolation thermique et le tuyau externe de manière à séparer la surface périphérique externe de la partie d'isolation thermique et la surface périphérique interne du tuyau externe et à maintenir un intervalle entre elles. La partie d'isolation thermique comporte des éléments d'isolation thermique unitaires indépendants, qui présentent des parties creuses et sont empilés dans une direction radiale autour de la surface périphérique externe du tuyau interne, et les éléments d'isolation thermique unitaires, ayant le même diamètre et étant empilés dans la direction longitudinale du tuyau interne, sont joints en continu de telle sorte que des espaces d'air de contact indépendants sont formés entre les éléments d'isolation thermique unitaires empilés.

    본 발명은 선박엔진의 연료공급용 액화천연가스 이송관을 게시한다. 이 이송관은 액화천연가스가 이동되는 유로를 형성하는 이너파이프와; 상기 이너파이프의 외주면을 감싸도록 형성되는 단열부와; 상기 단열부의 외주면과 그 내주면이 소정간격 이격되어 에어갭 형성될 수 있도록 단열부를 감싸는 아웃터파이프와; 상기 단열부와, 상기 아웃터파이프에 설치되어 상기 단열부의 외주면과 아웃터파이프의 내주면을 이격시키킴과 아울러 간격을 유지하는 간격유지수단을 구비하며, 상기 단열부는 이너파이프의 외주면을 중공부를 가지는 독립된 단위단열부재가 반경방향으로 적층되며 이너파이프의 길이 방향으로 적층되며, 동일한 직경의 단위단열부재들이 연속하여 접합됨으로써 적층된 단위단열부재들의 사이에 독립된 밀착에어갭이 형성된다.
