Disclosed is a high-insulation metal hose for liquefied natural gas (LNG) bunkering that prevents metal hoses from freezing and bursting even in harsh environments of extremely low temperatures. According to the disclosed invention, the high-insulation metal hose for LNG bunkering comprises: an internal metal hose in which a first inner flat tube and a second inner flat tube are arranged in-line, and an inner corrugated tube is connected by welding between the first inner flat tube and the second inner flat tube; and an external metal hose in which first outer flat tubes are welded at intervals on the outer peripheral surface of the first inner flat tube, second outer flat tubes are welded at intervals on the outer peripheral surface of the second inner flat tube, and an outer corrugated pipe is connected by welding between the first and second outer flat tubes. The space between the internal metal hose and the external metal hose is in a vacuum state for insulation.

    LNG 벙커링용 고단열성 메탈호스가 개시되어 있다. 개시된 본 발명은 제1 내부평관과 제2 내부평관이 인라인 상으로 배치되고, 상기 제1 내부평관과 제2 내부평관 사이는 내측 주름관이 용접에 의해 연결된 내부 메탈호스; 및 기 제1 내부평관의 외주면에는 제1 외부평관이 간격을 두고 용접되며, 상기 제2 내부평관의 외주면에는 제2 외부평관이 간격을 두고 용접되고, 상기 제1, 2 외부평관 사이는 외측 주름관이 용접에 의해 연결된 외부 메탈호스;로 구성되되, 기 내부 메탈호스와 외부 메탈호스의 사이공간은 단열을 위하여 진공상태인 것을 특징으로 한다.
