The invention relates to the technical field of marine transportation tank bodies, and provides a marine LNG double-layer liquid tank pipeline connecting structure and a marine liquid tank, the marine LNG double-layer liquid tank pipeline connecting structure comprises a sleeve and a jacketed pipeline, the sleeve comprises a sleeve part and a first deformation part, the jacketed pipeline is arranged in the sleeve in a penetrating mode to be used for being communicated with an inner layer container, and the first deformation part is arranged in the sleeve part. One end of the first deformation part is connected with the sleeve part, the other end of the first deformation part is connected with the jacketed pipeline, and the first deformation part is used for releasing stress at the joint of the sleeve part and the jacketed pipeline through deformation; by means of the first deformation part, stress in the direction of the jacketed pipeline can be released, and stress perpendicular to the direction of the jacketed pipeline can also be released, so that the reliability of the connecting part between the jacketed pipeline and the sleeve is improved, and the risk of cracking of the connecting part between the jacketed pipeline and the sleeve is reduced.

    本发明涉及船用运输罐体技术领域,并提供一种船用LNG双层液罐管路连接结构及船用液罐,该船用LNG双层液罐管路连接结构包括套管和夹套管路,所述套管包括套管部和第一变形部,所述夹套管路穿设于所述套管内以用于连通内层容器,所述第一变形部的一端与所述套管部连接,所述第一变形部的另一端与所述夹套管路连接,所述第一变形部用于通过变形以释放所述套管部与所述夹套管路连接处的应力;本发明中通过第一变形部不仅可以释放沿夹套管路方向的应力,还可以释放垂直于夹套管路方向的应力,从而以提高夹套管路与套管之间连接部位的可靠性,以减少夹套管路与套管之间连接处开裂的风险。
