Matrial	Duplex 2205 Stainless Steel
Size	WT: 1.65mm-30.75mm OD: 21.3-711mm Length: as customers' requirement
Technique	Hot Finish,cold Finish
Surface Treament	Annealed, Brightly Annealed, Polish
Application	Pressure vessel, high pressure pipe line, heat exchanger(chemical processing industry), oil and gas pipeline

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.
