As a professional bright annealing tube manufacturer, we have comprehensive knowledge about bright annealing technology that other bright annealing tube manufacturers may not be clear about. Bright annealing tubes are manufactured by using bright annealing equipment. Bright annealing equipment is special equipment to heat the stainless steel pipe to more than one thousand degrees Celsius and then place the tube under the protection of hydrogen, rapidly cooled to below 100 degrees Celsius. The main characteristic of bright annealing tube manufacturing system is not to use hydrogen repeatedly. Meanwhile, the exhaust emissions are able to burn. Spread of hydrogen gas into the surrounding air can be prevented. The devices that bright annealing tube manufacturers need to prepare are as follows:

1. The heating section. The heating section is consisting of the medium frequency power supply and induction coil. Induction heating part of bright annealing is based on IGBT transistor solid frequency conversion technology. According to the need, the output frequency can be changed in the 20-30 KHZ range. Output and load is a match in the IGBT induction solid state technology. Induction heating coil is usually brass solenoid structure. Brass internal is cooled by softened water. Induction coil is about 800 mm long, lined with a casing used for the insulation of the controlled atmosphere. Heat treatment time is short.

2. Cooling tunnel. Heated stainless steel tube gets into the cooling channels. By way of heat exchange, heated stainless steel tube can be cooled. Hydrogen will do further heat conduction to the outer special mold liner. The liner has a high thermal conductivity. Finally, the stainless steel tube can be cooled by external cooling water. The same as the heating part, all the work of cooling was conducted under the pure hydrogen atmosphere.

3. Circulating cooling system. Bright annealing tube manufacturers use soft water circulating system. The cooling water can be used repeatedly. Therefore, we will not waste resources. Bright annealing tube manufacturers can replace about 1.5 cubic meters of water once a year. So maintenance cost is low.

4. Gas control system. The system is used for continuous bright annealing to manufacture bright annealing tubes. Unique gas protection device is consisting of argon and hydrogen gas inlet, each equipped with a pressure reducing valve and pressure gauge, gas path, flow regulator and flow meter.

Apart from equipment mentioned above, there is other equipment used for bright annealing tube manufacturing such as temperature control system and console.
