The rolled flange refers to a kind of flange that is welded into a circular flange by rolling a strip of flat steel on the equipment. This flange is different from the laser cut flange. The cut flange does not have a crater and does not need to be welded. The rolled flange is generally rolled from flat steel with at least one crater. The advantage of this welded flange is that it saves more materials. If the inner core steel plate of the cut flange cannot have a suitable model, it can continue to be used to cut the flange, Will be wasted. There are also some processes that are laser cut into several arcs and then spliced into a circular flange. This flange process has many weld junctions, and the process is more complex than the rolled welding flange. In a word, the rolled flange made of flat steel will be more widely used due to saving labor and materials, so the cold rolling flange machine, the processing equipment for rolling flanges, is becoming more and more popular.
