One of the largest applications of induction mass heating is heating pipes and tubes. The choice of power and frequency depends on the material of the pipe, its diameter, and the wall thickness. Pipes and tubes are heated to a temperature that depends on what the manufacturers want to do.

Typical examples are :

• Induction annealing of pipes on a continuous line.
• Induction hardening of drill pipes used in rigs.
• End heating of pipes for hot forging and manufacturing of gas cylinders.
• Heating pipes to forging temperature for hot forming, bending
