Seam Annealing

Thermatool seam annealing systems can be provided for the complete size range of API pipe and for spiral pipe with any helix angle.

Systems include a mill mounted carriage for holding the inductor above the pipe, equipped with a quick lift feature to rapidly raise the inductor off the pipe to clear any damaging obstructions.

The system can also be equipped with a fully automatic seam tracking system to ensure the complete annealing of the weld seam if it should vary from the vertical position.

Thermatool powers its seam annealing systems with a rugged, reliable VIP Series inverter power supply, which are available in 500 KW or 1,000 KW outputs for operation at 1, 3 or 6 kHz.
