Superior Surface Finish:
The traditional annealing:
Open furnace---Oxygen atmosphere---form Scale, tarnish the material, For more than 12m tubes this method is hard to clean inner surface.
A special bright annealing:
Closed furnace---Intert atmosphere use noble gases(Nitrogen and argon) Preventing Oxygen to contact with material---Surface finish is clean, bright and precision, which is an excellent starting point for further process, like electro-polishing and mechanical polishing. For more than 12m tubes, this method is much cleaner smoother on both inner and outer surface.
Packing:
Each tube in a plastic bag, then put tubes in a seaworthy woven bag ,each unit weight 400kg-500kg/bundle.
With strong wood structure box packing by containers loading and shipping.
Or as customer's requirement.
