PROBLEM TO BE SOLVED: To provide a liquefied gas tank in which a well can be easily manufactured.SOLUTION: The liquefied gas tank comprises: an open part 12 formed in a bottom part 11 and composed of a straight portion 12a and a curved portion 12b; a straight-shaped member 21 composed of one piece of a flat surface web 21a forming a flat surface and a pair of straight flanges 21b disposed along the upper and lower ends of the flat surface web 21a; and a curve-shaped member 22 composed of one piece of a curved surface web 22a forming a curved surface and a pair of curved flanges 22b disposed along the upper end and lower ends of the curved surface web 22a; and a bottom plate 23 for forming the bottom of a well 2. The straight-shaped member 21 and the curve-shaped member 22 are butt-welded together to form an annular body 24. The bottom plate 23 is butt-welded to the inner edge of the lower end of the annular body 24. The outer edge of the upper end of the annular body 24 is butt-welded to the inner edge of the open part 12.

    【課題】ウェルを容易に製作することができる液化ガスタンクを提供する。【解決手段】底部11に形成され直線部12aと曲線部12bとから構成される開口部12と、平面を形成する一枚の平面ウェブ21aと平面ウェブ21aの上端及び下端に沿って配置される一対の直線フランジ21bとから構成される直線状形材21と、曲面を形成する一枚の曲面ウェブ22aと曲面ウェブ22aの上端及び下端に沿って配置される一対の曲線フランジ22bとから構成される曲線状形材22と、ウェル2の底部を形成する底板23と、を有し、直線状形材21及び曲線状形材22を突き合わせ溶接して環状体24を形成し、環状体24の下端の内縁に底板23を突き合わせ溶接し、環状体24の上端の外縁を開口部12の内縁に突き合わせ溶接する。【選択図】図2
