Complete set of online anneal equipments of steel pipe welding seam

Induction annealing equipment of steel pipe takes the induction heating coil as the main components for continuous welding pipe machine, it heats the seam which has just been welded and quenched, to above the critical temperature and anneals it (seam) to avoid the potential crack. The fine-crystal-particle structure produced by this process will guarantee a steel pipe tenacious that meet all standard requirements of the specification.

Single frequency: 300~600KW

Working frequency: 0.5~8KHZ

Heating steel OD: ≥45mm

Heating steel thickness: 1~25mm

Tracking range for tube seam: ±15°

  • Flexible avoid function for welding seam burr.
  • The output transformer with spaced winding between special primary and secondary which increases system efficiency.
  • Operation flexible and reliable.
