How to prevent corrosion in Duplex Tubes?

  • Preventing corrosion in Duplex Tubes involves implementing several proactive measures to maintain the integrity and longevity of the piping system. First and foremost, proper material selection is critical. Choosing the correct duplex stainless steel grade based on the specific environment and application helps ensure optimal corrosion resistance. Common grades such as 2205 and 2507 are selected for their ability to withstand corrosive substances and harsh conditions.
  • Additionally, adopting effective corrosion prevention methods, such as regular inspection, maintenance, and the application of protective coatings, is essential. Routine inspections can identify early signs of corrosion, allowing for timely repairs or replacements. Protective coatings, such as passivation treatments or corrosion inhibitors, can be applied to the surface of Duplex Tubes to create a barrier against corrosive elements. Proper installation practices, including avoiding contact with incompatible materials and minimizing exposure to aggressive chemicals, prevent corrosion in Duplex Tubes.

Manufacturing Process of Duplex Tubes

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

  • Step 1 : Raw Material Selection
    To begin the process of creating 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 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 Duplex.
  • Step 3 : Forming
    After the molten 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 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 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 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.
