Titanium alloy tube, a special pipe made of titanium alloy, has won wide praise and application in many industrial fields due to its excellent characteristics such as lightweight, high strength, high temperature resistance, and corrosion resistance. Its excellent mechanical and stamping properties, coupled with the ability to be processed through welding and other processes, and the strength of the welded joint is almost equivalent to that of the base metal, the cutting performance is also excellent, making titanium alloy pipes play an irreplaceable role in many fields such as chemical equipment, petroleum, power, seawater desalination, construction, and daily necessities.
In the manufacturing process of titanium alloy pipes, the precision of processing technology directly affects the final performance and quality of the pipes. From the initial melting to the final forging, every step has undergone strict control and optimization.
In the melting stage, advanced plasma gun or electron beam gun technology is used to directly melt a mixture of sponge titanium and intermediate alloy to obtain high-purity tubular hollow ingots. During this process, precise control was carried out on parameters such as the ratio of raw materials, melting temperature, and melting time to ensure that the chemical composition and microstructure of the ingot reached their optimal state.
For traditional columnar titanium alloy ingots, they are made into tube billets through drilling technology and titanium chips are recovered for remelting to improve material utilization and reduce costs.
The next stage is the forging phase, which is a crucial step in the forming process of titanium alloy tubes. After heating the as cast billet to a specific temperature, perform three radial forging processes. Every forging requires replacing the core rod and strictly controlling the deformation and movement speed of the billet. Through this series of forging processes, the cross-sectional shape of the billet gradually changes from an initial outer square and inner circle to an outer octagonal and inner circle, and finally returns to a circular shape. During this process, the control of temperature and speed is extremely critical, as they directly affect the mechanical properties, microstructure, and surface quality of the pipe.
In addition, advanced testing technology and quality control measures are adopted during the forging process to ensure that every detail of the pipe meets the standards, thus meeting the various needs and application scenarios of customers.
