The medium frequency seam normalizer is mainly applied for steel pipe welding straight seam annealing process operation.

The seam normalizer is mainly for steel pipe annealing process operation.

The application of seam annealing method promotes steel pipe quality level. Induction heater is the main part of steel pipe induction annealing equipment, which heat the pipe seam welded and quenched to critical temperature, this process can reduce welding stress and potential crack, and the produced close grains structure can guarantee producing tenacious steel pipe meeting all standard specifications. With the advantage of seam rapidly sectional heating, the oxydation and deformation of steel pipe can be made minimum, and the precise diathermancy make the close grains in seam area consistance with its parent material.
