SSAW Steel Pipe Manufacturing Process:

Spiral steel pipe (SSAW)is a spiral seam steel pipe made of strip steel coils as raw materials, often extruded and formed by automatic double-wire double-sided submerged arc welding. The spiral steel pipe feeds the strip steel into the welded pipe unit. After rolling by multiple rollers, the strip steel is gradually rolled up to form a round tube blank with an open gap. The reduction of the squeeze roller is adjusted to control the weld gap at 1~ 3mm, and make both ends of the welding joint flush.

Machine of manufacturing SSAW steel pipe

Edge planing machine, edge milling machine, pipe cutting machine,butt welding machine, pinching machine, hydraulic testing machine.
