Ship heat insulation cabin penetrating piece and ship

The utility model discloses a ship heat insulation cabin penetrating piece and a ship. Wherein the cabin penetrating pipe penetrates through a cabin wall or a deck, the casing pipe is arranged outsidethe cabin penetrating pipe in a sleeving mode, the corrugated plate is welded between the cabin penetrating pipe and the casing pipe, fluid pipes are connected to the two ends of the cabin penetrating pipe respectively, the outer side wall of the casing pipe is welded to the cabin wall or the deck, and a heat insulation layer is arranged between the cabin penetrating pipe and the casing pipe. Andthe heat insulation layer completely wraps the corrugated plate. And the corrugated plate is elastically deformed between the cabin penetrating pipe and the sleeve to weaken the influence of thermalexpansion and cold contraction on the cabin wall or the deck, so that the cabin wall or the deck is prevented from being broken. Due to the existence of the corrugated plates, the heat transfer area of the heating medium fluid
