Intermediate Frequency Quenching Heat Treatment

On-line intermediate frequency annealing equipment is a special equipment for longitudinal welded pipes instead of petroleum welded pipes on the basis of absorbing foreign advanced equipment experience and combined with the actual domestic situation.

Suitable for on-line weld annealing of 114-610 straight seam steel pipes.

Sweep frequency zero-voltage software is activated, with a success rate of 100%, digital triggering at equal intervals, and precise control of output power.

The whole set of equipment adopts PLC, touch screen control, with temperature nose ring control and temperature display.

It has the functions of electric ascent and descend, electric forward and backward, arc tracking, etc., which is convenient to adjust the gap between the sensor and the steel pipe weld.
