Precision Tubing  Bright annealed tube A269

Superior Surface Finish

The traditional annealing method is performed in a called open furnace, where the atmospheric oxygen causes scaling of the heat treated materials, which makes the surface rough. MTSCO has developed a special bright annealing process, the heat treatment is performed in a so called closed furnace. The heat treated materials is protected by an inter gas atmosphere, which guarantees the oxygen cannot enter the furnace or come in to contact with the materials and react to form scale on or tarnish the materials. The surface finish is clean, bright and precision, which is an excellent starting point for further process, like electro-polishing and mechanical polishing.

Especially for the tube with length more than 12 meters, the traditional pickling tube is very hard to clean the inner surface, however, with the bright annealing method, our tubing is much cleaner, smoother on both inner and outer surface.
