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
