90m/Min Square Tube Mill for 20x20-60x60mm Carbon Steel Pipes

Blue Welded Pipe Production Line 90m/Min Size 20*20-60*60mm Square Tube Mill

Product Information

Blue Welded Pipe Production Line 90m/Min Size 20*20-60*60mm Square Tube Mill  adopts roller type forming principle and high-frequency induction welding. The strip is fed into the forming machine by the feeding device in the mill and the forming roller continuously rotate and press the strip into the required shape. Due to the skin and the kindred effect, the high-frequency current is concentrated on the weld joint that is heated rapidly and reaches the welding temperature. The tube seam is welded under the pressure of squeeze rollers. The finished welded tube with required size can obtained after the cooling, sizing and primary straightening.
