The present invention discloses 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.
本发明公开了船舶发动机燃料供给用液化天然气输送管。该输送管包括:内管,形成用于液化天然气移动的流路;绝热部,形成为围绕所述内管的外周面;外管,围绕所述绝热部,并使所述绝热部的外周面和所述外管的内周面隔开预定的间隔以形成气隙;以及间隔维持机构,设置在所述绝热部与所述外管之间,以将所述绝热部的外周面和所述外管的内周面隔开并维持间隔,其中,在所述绝热部中,具有中空部的独立的单位绝热部件在内管的外周面上沿着内管的半径方向层叠且沿着内管的长度方向层叠,并且单位绝热部件连续地接合,从而在层叠的单位绝热部件之间形成独立的紧密气隙。
