The number of storage rolls is 10 rolls. The steel plate of the storage bin is transported to the finishing press unit through the conveying device. The finishing press unit has two functions, one is to accurately level the steel plate, and the second is to make a groove for both ends of the leveling steel plate to facilitate the next step of welding. That is the process of steel plate forming for steel pipe, the use of cold extrusion forming principle, its forming process is like this, the use of circular foveaux, slowly deformable steel plate in stages, and finally the two ends of the steel plate are rounded into a circle, the shaped steel pipe arc welding, arc welding efficiency is high and the shape variable is small, the welded steel pipe with groove cutting tools to remove excess welding ribs, After the welded steel pipe is removed, it is cut into the specified length, generally 12 meters, and the cut steel pipe is transported to the testing workshop for testing.
