Recently, in order to reduce the time required for the cover frame to reduce the rework waste and improve the production efficiency, Nantong Zhongyuan Heavy Industry Co., Ltd. has improved the butt weld process of the folding hatch girder web and the top plate, which not only greatly saves the flap and The lifting time also reduced the repair rate of the problem from the original 25% to 0, which solved the raw materials, other auxiliary materials and waste of working hours caused by the heavy seam problem, and obtained the unanimous approval of the shipowner's ship inspection.
It is reported that for the folding hatch, Nantong COSCO Heavy Industries has modified the butt weld size of the trunk girder web and the roof panel without violating the design structure, so that even in the group production, the girder web joints The interchange of the left and right sides of the position also ensures that the splicing seam of the girders of the girders and the splicing joints of the roof are completely staggered during the assembly phase, thereby avoiding the waste of rework and the influence of the construction period caused by such re-arrangement.
Our products are widely used in various factories, civilian building, warehouse and other steel structure building.
