Bright Annealing is the process of heat treatment, which, tube surfaces made clean and free of foreign matter. The annealing atmosphere must be relatively free of oxygen (if a bright result is desired). This is accomplished by removing nearly all gas (creating a vacuum) or by displacement of oxygen and nitrogen with dry hydrogen or argon. 
The tube is not pickled afterwards as this is not necessary – and pickling can also potentially damage the oxide layer. As a result, with a cleaner and brighter appearance and a controlled inside-surface condition, bright annealed tubing has a much smoother surface which imbues the component with better resistance to pitting corrosion
