Titanium alloy tubing, this special tubing crafted from titanium alloy, has won wide acclaim and applications in many industrial fields for its excellent characteristics such as light weight, high strength, high temperature resistance and corrosion resistance. Its excellent mechanical properties and stamping properties, coupled with the fact that it can be processed through welding and other processes, and the strength of the welded joints is almost equal to the base metal, and the cutting and machining performance is also very good, so that the titanium alloy tubes play an irreplaceable role in chemical equipment, petroleum, electric power, desalination, construction, and daily necessities in many fields.
In the manufacturing process of titanium alloy tubes, the fineness of the machining process directly affects the final performance and quality of the tubes. From the initial melting to the final forging and forming, each step is strictly controlled and optimized.
In the melting stage, a mixture of titanium sponge and intermediate alloys is directly melted by means of advanced plasma or electron-beam gun technology in order to obtain a tubular hollow ingot of high purity. During this process, parameters such as raw material ratios, melting temperatures and melting times are precisely regulated to ensure that the chemical composition and microstructure of the ingots are optimized.
For conventional columnar titanium ingots, they are made into tube billets by drilling process and recycling titanium chips for remelting to improve material utilization and reduce cost.
Next comes the forging stage, a critical step in the process of forming titanium alloy tubes. After the cast billet is heated to a specific temperature, it is radially forged three times. Each forging requires a mandrel change and strict control of the amount of deformation and speed of movement of the billet. Through this series of forging processes, the cross-sectional shape of the billet is gradually transformed from an outer square with a rounded inner part to an outer octagon with a rounded inner part, and finally back to a round shape. In this process, the control of temperature and speed is extremely critical, and they directly affect the mechanical properties, microstructure and surface quality of the pipe.
In addition, advanced testing technology and quality control means are used in the forging process to ensure that every detail of the pipe meets the standard, so as to meet the various needs and application scenarios of customers.
