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 bottom plane part and a corrugated protruding part which are arranged in a stacked mode, the corrugated protruding part has a certain height relative to the bottom plane part, and the height is smaller than the length of the bottom plane part; the projection of the corrugated protruding part on the bottom plane part coincides with the bottom plane part. The bottom plane part is provided with a plurality of edges, and the edges of the bottom plane part are connected with the corrugated protruding parts respectively. According to the corrugated plate, transverse and vertical low-temperature contraction deformation is absorbed at the same time through the corrugated convex structures, and internal stress generated by low-temperature contraction of the corrugated plate in a large-temperature-difference-change working scene can be 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叠放设置的底部平面部和波纹凸起部,所述波纹凸起部相对所述底部平面部具有一定的高度,所述高度小于所述底部平面部的长度;所述波纹凸起部在所述底部平面部上的投影与所述底部平面部重合;所述底部平面部具有多条边,所述底部平面部的各条边分别与所述波纹凸起部连接。本申请通过波纹凸起结构同时吸收横向和竖向的低温冷缩形变,可降低波纹板在大温差变化工作场景中低温收缩产生的内应力。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。
