In the manufacturing process of titanium alloy pipes, the precision of the processing technology directly affects the final performance and quality of the pipe. From initial smelting to final forging, every step is strictly controlled and optimized.
In the smelting stage, advanced plasma gun or electron beam gun technology is used to directly smelt sponge titanium and master alloy mixture to obtain high-purity tubular hollow ingots. During this process, parameters such as the ratio of raw materials, melting temperature and melting time are precisely controlled to ensure that the chemical composition and microstructure of the ingot reach the optimal state.
For traditional columnar titanium alloy ingots, they are made into tube blanks through a drilling process, and titanium scraps are recovered for remelting to improve material utilization and reduce costs.
Next is the forging stage, which is a key step in the titanium alloy tube forming process. After the cast tube blank is heated to a specific temperature, radial forging is performed three times. Each forging requires replacing the mandrel and strictly controlling the deformation and movement speed of the tube blank. Through this series of forging processes, the cross-sectional shape of the tube blank gradually changes from an initial square outside and a circle inside, to an octagon outside and a circle inside, and finally returns to a circle. 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 detection technology and quality control methods are used during the forging process to ensure that every detail of the pipe meets standards, thereby meeting the various needs and application scenarios of customers.
