Technical Q&A: Induction Heating Machine for Steel Pipe

1. Overview of Steel Pipe Induction Heating Machine

A steel pipe heat treatment machine is a special electromagnetic thermal processing equipment designed for tubular metal materials. Based on Faraday’s electromagnetic induction law, the high-frequency power supply generates an alternating magnetic field inside the induction coil. Eddy current is produced on the pipe surface, converting electric energy into thermal energy for rapid heating. This equipment is widely applied in steel pipe bending, thermal expansion, anti-corrosion pretreatment, quenching and tempering processes. Compared with traditional flame heating, it features contactless heating, clean combustion and easy automatic production.
