Induction preheating in the tube and pipe industry

Induction produces quick, accurate, controllable and repeatable heat. This makes it an excellent method for preheating tubes and pipes to prevent cracking, reduce hardening structures and increase welding speed.


EFD Induction offers a series of solutions for induction preheating within tube and pipe. Some examples are heating prior to welding, tin remelting, galvanizing, pipe forming and bending, and application of plastic powder or paint to tube.


You can also use induction preheating  to get better adhesion of insulation round heating pipes (compare with the process of adhering insulation round cables and wires).
