1. Overview of titanium tube materials

       Titanium tubes are characterized by high strength, low density, excellent mechanical properties, toughness, and superior corrosion resistance. They are primarily used to manufacture compressor components for aircraft engines and are also widely applied in structural components of rockets, missiles, and high-speed aircraft. Additionally, they play a significant role in various fields such as electrodes in the electrolysis industry, condensers in power stations, heaters in petroleum refining and seawater desalination, and environmental pollution control devices.

       II. Production Process Flow of Titanium Tubes

       The production process of titanium tubes in Baoji region mainly includes the following steps:

       Melting: Titanium raw materials are melted into titanium liquid.

       Forging: The molten titanium liquid is forged to form a preliminary tubular shape.

       Rolling: Through the rolling process, the forged titanium material is processed into titanium tubes with the required size and shape.

       Heat treatment: including steps such as annealing, solution treatment, and aging treatment, to enhance the mechanical properties and corrosion resistance of titanium tubes.

       Annealing: The purpose is to eliminate internal stress, enhance plasticity, and improve structural stability, thereby achieving better comprehensive performance. Depending on the type of alloy, the annealing temperature varies. For example, the annealing temperature for α alloys and (α+β) alloys is typically chosen to be 120~200℃ below the (α+β)→β phase transformation point.

       Solution treatment and aging: The purpose is to enhance the strength of titanium tubes. Alpha titanium tubes and stable beta titanium tubes cannot undergo strengthening heat treatment and are only subjected to annealing treatment; whereas alpha plus beta titanium tubes and metastable beta titanium tubes containing a small amount of alpha phase can be further strengthened through solution treatment and aging treatment.

       III. Special heat treatment process

       In order to meet the special requirements of titanium tubes, titanium tube manufacturing enterprises in Baoji area have also adopted various special heat treatment processes, such as double annealing, isothermal annealing, β heat treatment, and thermomechanical treatment. The application of these processes has further improved the performance and application range of titanium tubes.

       IV. Market Application and Prospects

       Baoji titanium tubes, with their excellent performance and wide range of applications, hold vast development prospects in the market. As the aerospace, petrochemical, and offshore engineering sectors continue to evolve, the demand for titanium tubes will also persistently grow. Simultaneously, with technological advancements and continuous process innovations, the production efficiency and product quality of Baoji titanium tubes will also be enhanced, providing the market with an increased supply of titanium tube products.

       In summary, the titanium tube material technology in Baoji region boasts profound heritage and rich experience. Through continuous optimization of production processes and technological innovation, Baoji titanium tubes will demonstrate even broader development prospects in the future market.
