The invention relates to a piping structure for extremely low temperature liquid, which is suitable for ships for storing extremely low temperature liquid with boiling point below-196 DEG C under normal pressure. This piping structure is provided with: low-temperature piping (10) that is disposed along a structural member (4) of a ship (1) at a position separated upward from the structural member (4) and through which an extremely low-temperature liquid flows; and a porous heat dissipation layer (20) which is provided below the low-temperature pipe (10) so as to cover the structural member (4), and which, when liquefied air is formed on the surface of the low-temperature pipe (10), receives and evaporates the droplets of the liquefied air.

    一种极低温液体用配管结构,适用于贮存常压下的沸点为‑196℃以下的极低温液体的船舶。该配管结构包括:低温配管(10),在相对于船舶(1)的结构部件(4)向上方离开的位置处沿着该结构部件(4)布设,并且让极低温液体流通;以及,多孔的散热层(20),在低温配管(10)的下方以覆盖结构部件(4)的方式而被设置,在低温配管(10)的表面形成有液化空气的情况下承接该液化空气的滴落并使之蒸发。
