A789 UNS S31803 Super Duplex 2507 Oil Gas Stainless Pipe Coiled Tubing

A789 UNS S31803 Super Duplex 2507 Oil Gas Stainless Pipe Coiled Tubing

Manufacture:

Pipes shall be made by the seamless process and shall be either hot finished or cold finished.

Application:

high pressure pipe line, heat exchanger(chemical processing industry), oil and gas pipeline

Size Range:
OD:21.3-711mm

WT: SCH5/SCH10/SCH40/SCH80/SCH160/XXS(1.65mm-30.75mm)

Length: max 12000mm

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.

Material:

Grade: Duplex 2205

Mechanical Properties:

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.
