Document Type and Number:
WIPO Patent Application WO/2020/235970
Kind Code:
A1
Abstract:
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.
