Titanium alloy tube has high strength, low density, good mechanical properties and excellent toughness and corrosion resistance. In addition, titanium alloy tube has poor processing performance, is difficult to machining, in thermal processing, it is very easy to absorb hydrogen, oxygen, carbon, nitrogen and other impurities. There is poor wear resistance of titanium alloy tube, the production process of titanium alloy tube is complex. Industrial production of titanium began in 1948. With the development of aviation industry, the titanium industry developed at an average growth rate of about 8% every year. At present, the annual output of titanium alloy pipe has reached 4 tons in the word, and the grades of titanium alloy pipe are nearly 30. The titanium alloy tube such as Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and industrial pure titanium (TA2, TA3 and TA1) were widely used.
Titanium alloy tubes are mainly used in the manufacture of aircraft engine compressor components, next are used in the structure of the rocket, missile and high-speed aircraft. In the metaphase of 60s, titanium and its alloys have been applied in the general industry for the production of electrolytic industrial electrodes, power station condenser, oil refining and desalination of the heater, and environmental pollution control devices, etc. Titanium and its alloys have become a kind of corrosion resistant structural materials. It is also used in the production of hydrogen storage materials and shape memory alloys.
In 1956,China began to study the titanium and titanium alloy tubes, in the middle of the 60s, China began to produce the titanium material and study the TB2 alloy.
