Mid frequency heater
To improve the quality of welding, to prevent the pipe material lattice coarsening caused by delayed cracking the temperature of the base metal needs to be strictly controlled before welding. Our resistance heaters are designed to satisfy the pipe welding process needs. The heater using electromagnetic induction heating technology, with heating speed, high thermal efficiency, good controllability.
