As it is impossible for a pipe-shaped workpiece to be 100% circular or for the turning rolls to be 100% level, the workpiece moves laterally as it rotates on the turning rolls. SANGNIM MSP Anti Drift Turning Roller system prevents drift when the workpiece deviates to the side, by having a sensor receive the signal, and through PLC automatic control, the servo motor operates the roller to return the workpiece to its original position.

  • The total length of the finished product of a large pipe structure (monopile, pressure vessel, etc.) is easily over 100m, and the length is increased by continuously welding unit cans.
  • Lateral movement occurs when rotating the material during machining and welding of can connections.
  • This amount of lateral movement come to very large, which is a fatal factor in welding defects
  • Improves machining and weldability by controlling the axial movement amount as follows.
