To propose piping structure in a multi-shell tank, in which pipe penetration portions of the tank can be integrated.SOLUTION: A multi-shell tank comprises an inner tank, an outer tank in which the inner tank is housed, an outermost shell in which the inner tank and the outer tank are housed, and inter-tank piping which is passed between the inner tank and the outer tank. The inner tank has an inner tank main body, and an inner tank projecting portion which penetrates the outermost shell from the inner tank main body and projects to the outside of the outermost shell. The outer tank has an outer tank main body covering the inner tank main body, and an outer tank projecting portion which penetrates the outermost shell from the top of the outer tank main body, projects to the outside of the outermost shell, and surrounds at least a portion of the inner tank projecting portion. The outer tank projecting portion has, in at least a portion thereof, an outer tank exposed portion exposed to the outside of the outermost shell. The inter-tank piping is passed between the inner tank main body and the outer tank main body, is passed between the inner tank projecting portion and the outer tank projecting portion, penetrates the outer tank exposed portion of the outer tank projecting portion and is extended to the outside.SELECTED DRAWING: Figure 2
【課題】多重殻タンクにおける配管構造であって、槽の管貫通部が集約され得るものを提案する。【解決手段】内槽と、内槽を収容した外槽と、内槽及び外槽を収容した最外殻と、内槽と外槽との間を通された槽間配管とを備える。内槽は、内槽本体と、内槽本体から最外殻を貫いて最外殻の外側へ突出した内槽突出部とを有する。外槽は、内槽本体を覆う外槽本体と、外槽本体の頂部から最外殻を貫いて当該最外殻の外側へ突出し且つ内槽突出部の少なくとも一部分を包囲する外槽突出部とを有し、外槽突出部は最外殻の外側に露出した外槽曝露部を少なくとも一部分に有する。槽間配管は、内槽本体と外槽本体との間を通され、内槽突出部と外槽突出部との間を通され、且つ、外槽突出部の外槽曝露部を貫いて外側へ延出されている。【選択図】図2
