The invention relates to an LNG ship liquid cargo containment system corrugated unit and a corrugated plate, the LNG ship liquid cargo containment system corrugated unit comprises a center plane part with a certain shape, all edges of the center plane part are connected through corresponding corrugated protrusions, the corrugated protrusions corresponding to every two adjacent edges are connected with each other, and the corrugated plate is arranged on the center plane part. The corrugated bulges have a certain height relative to the central plane part; the bottoms of the corrugated bulges and the central plane part are positioned on the same plane; and the shape of the bottom edge of the corrugated unit is the same as that of the central plane part. Longitudinal and transverse cold shrinkage deformation margins are pre-stored in a corrugated protrusion mode, and compared with a straight material, the cold shrinkage internal stress borne by a single mass point at the low temperature is reduced. The corrugated unit form is simple in structure and easy to machine, forming is easy to control in the machining and stamping process, the thinning rate is uniform and dispersed, and the yield is high.
本申请涉及一种LNG船液货围护系统波纹单元及波纹板,其中,所述LNG船液货围护系统波纹单元包括具有一定形状的中心平面部,所述中心平面部的各条边通过对应的波纹凸起进行连接,每相邻两条边对应的所述波纹凸起均相互连接,所述波纹凸起相对于所述中心平面部具有一定的高度;所述波纹凸起的底部与所述中心平面部位于同一平面上;所述波纹单元底部边缘的形状与所述中心平面部的形状相同。本申请通过波纹凸起的形式预储存纵横两向的冷缩形变余量,相较平直材料在低温下单个质点受到的冷缩内应力减小。波纹单元形式结构简单,易于加工,加工冲压中成形易控至,减薄率均匀分散,良品率高。
