[0027] Examples:
[0028] Plug-in nozzle 2 size: inner diameter is 1800mm, wall thickness is 280mm; cylinder 1 size: inner diameter is 3400mm, wall thickness is 210mm; welding method is:
[0029] As shown in Figure 2, it is a schematic diagram of the lower weld seam. First, use a crane to insert the connecting pipe 2 into the holed cylinder 1, and assemble it as required. The lining plate 13 is welded on the outside of the cylinder at the bottom of the groove, and then the cylinder is welded. Twelve anti-deformation rigid fixed ribs 14 are evenly arranged on the outer circumference of the body 1 and the connecting pipe 2 and welded properly;
[0030] Then use a crane to place the assembled non-right-angle intersecting plug-in nozzle and the cylinder workpiece in the orientation shown in Figure 2, that is, the nozzle 2 is placed vertically on the ground, the cylinder 1 is tilted up, and the workpiece is placed and fixed. The lower port of the body 1 is installed with the working pl...
