SOLID STATE EQUIPMENT FOR BRIGHT ANNEALING OF STAINLESS STEEL PIPES

EQUIPMENT TYPE

Solid state induction heating equipment based on transistor, MOSFET or IGBT technology.

OUTPUT FREQUENCIES

Ranging from 10 to 200 KHz

USE

Induction heating for continuous bright annealing, in a controlled atmosphere with pure Hydrogen, of stainless steel welded pipes. Equipment to be cleaned with Argon.

TYPICAL APPLICATIONS

Food industry, like for example machinery for refrigerating drinks; chemical and pharmaceutical industry; heat exchanger ecc.

WORK PROCESS

The system is installed downstream TIG or laser weld lines. The temperature during the annealing process, is of approx. 1200°C; then the subsequent conduction-cooled system avoids making circulate large gas volumes. Due to the controlled atmosphere, the pipe produced is cleaned and polished.

COMPOSITION

Gas control system, cooling tunnel, adjustable support frame, water cooling system, temperature control system and control desk.

OPTIONS Remote-controlled Supervision System.
