What are the production processes of spiral steel pipe?

The spiral steel pipe feeds the strip steel into the welded pipe unit. After rolling through multiple rolls, the strip is gradually rolled up to form a circular tube blank with an open gap. The reduction of the pressing roll is adjusted to control the weld gap in 1~ 3mm and make the ends of the solder joint flush.
