Process Flow
Bright Annealing finned pipe is produced by heat-treating (annealing) steel with a controlled protective atmosphere furnace. After heat-treatment, the steel has a reflective, mirror-like appearance, but may also have some imperfections and cloudiness. Bright annealing stainless steel can be buffed to attain a more reflective finish, and is often specified for applications where a highly reflective surface is desired.
On-Line Fixing & Fusing (Anealing) equipment can heat the stainless steel welded pipeto 1050°C then cool it to the temperature lower than 100 °C under the protection of hydrogen.The heating power supply of the intermediate ferquency induction is the newest DSP+IGBT structure.With DSP digital control system,there are self protection and self diagnostic functions.With small volume,it heats pipes rapidly and efficiently with energy-saving and low-waste features.The especially developed inducer designed according to the features of stainless steel can save 15%-20% energy in contrast of other products of the same class.Using hydrongen as of gas every minute.
