Inline Bright Annealing Equipment

In-line Bright Annealing Equipment is mainly used to in-line anneal AISI 300 and AISI 400 stainless steel pipe. The annealing process is completed under a controlled atmosphere (Pure Hydrogen) in order to assure the brightness of the surface and to re-gain the natural hardness of the material before forming and welding. Tube straightening is not required after the process.

In-line bright annealing equipment is based on Mosfet and IGBT transistor technology, and is available with output frequencies ranging from 10-400kHz and output power from 50-500kW according to requirements. It is used for continuous bright annealing, in a controlled atmosphere (pure hydrogen, while argon is utilized to flush the unit) of stainless steel welded pipes.

This type of equipment is generally installed on weld lines that utilise the TIG or laser method and it enables continuous annealing and allows the surface of the pipe produced to be cleaned and polished. The pipe is heated to a temperature of approximately 1,200 C and is then conduction-cooled so that large volumes of gas are not made to circulate. The equipment is supplied complete with gas management system, inductor, cooling tunnel, mobile support, equipment cooling system, temperature control system and control panel.
