Bright Annealed Tubes (BA Tubes)/High Precision Tubes

What is Bright Annealing Tube?

Bright annealing is a solution- annealing process performed in a vacuum or a controlled atmosphere containing hydrogen. This is to reduce the surface oxidation to a minimum which results in a bright surface and very thin oxide layer.

Hengyang Piping supplies bright annealing tubes both welded and seamless, stainless steel and carbon steel. Steel grades include 304, 316L, 904L, S32205, S32750, S32760, A179 etc.
