What is Super Duplex Tube?

A Super Duplex Tube is a type of tubing manufactured from a specialized alloy known for its superior corrosion resistance, exceptional mechanical strength, and durability. Comprising a high concentration of chromium, nickel, and molybdenum, super duplex tubes exhibit a dual-phase microstructure that combines the best attributes of both ferritic and austenitic stainless steels. This unique composition enables super duplex tubes to withstand highly corrosive environments such as offshore oil and gas platforms, chemical processing plants, and marine applications. It makes them an ideal choice for industries where extreme corrosion resistance and structural integrity are paramount.

Manufacturing Process of Super Duplex Tubes

Super Duplex Tube is produced in seven steps. It manufactures a wide range of shapes, goods, and parts, ranging from Super Duplex Tube and Coil.

Step 1 : Raw Material Selection
To begin the process of creating Super Duplex, raw materials such as iron ore and other elements including nickel, chromium, and molybdenum are carefully selected. The choice of alloying elements depends on the specific properties that the Super Duplex is intended to possess.
Step 2 : Smelting and Melting
Once the raw materials have been selected, they are smelted in a furnace to create a molten metal alloy. The composition of the alloy is closely monitored and controlled to achieve the desired grade of Super Duplex.
Step 3 : Forming
After the molten Super Duplex has been produced, it is cast into different shapes and forms, depending on its intended use. The most common shapes include slabs, billets, blooms, or ingots.
Step 4 : Primary & Secondary Steelmaking
The subsequent step is primary steelmaking, which can be accomplished through different methods such as the Basic Oxygen Furnace (BOF) or the Electric Arc Furnace (EAF). At this stage, impurities like carbon are eliminated to achieve the desired chemical composition.
Step 5 : Casting
The molten Super Duplex is then cast into semi-finished forms, which can take the shape of plates, sheets, bars, or other forms. Continuous casting or ingot casting methods are usually employed for this purpose.
Step 6 : Hot Rolling
In the case of products like Super Duplex Tubes, the semi-finished castings are hot-rolled to achieve the desired thickness and shape. During this process, the thickness of the castings is reduced while improving their mechanical properties.
Step 7 : Cold Rolling and Annealing
In the case of specific Super Duplex products such as thin sheets and coils, cold rolling is employed to further reduce the thickness and enhance surface finish. To relieve stresses and enhance corrosion resistance, annealing is frequently performed.
