Titanium is an important structural metal developed in the 1950s. Titanium alloys are widely used in various fields because of their high specific strength, good corrosion resistance and high heat resistance. Many countries around the world have recognized the importance of titanium alloy materials and have successively researched and developed them for practical applications. Titanium is the ⅣB element in the periodic table, the appearance of steel, melting point of 1 672 ℃, is a refractory metal. Titanium is abundant in the earth's crust, much higher than Cu, Zn, Sn, Pb and other common metals. China's titanium resources are extremely rich, only in Sichuan Panzhihua area found in the very large vanadium and titanium magnetite, associated titanium metal reserves of about 420 million tons, close to the sum of foreign proven titanium reserves.　Titanium alloys can be divided into heat-resistant alloys, high-strength alloys, corrosion-resistant alloys (titanium-molybdenum, titanium-palladium alloys, etc.), low-temperature alloys and special functional alloys (titanium-iron hydrogen storage materials and titanium-nickel memory alloys), etc.

Titanium tube is light in mass, high in strength and superior in mechanical properties. It is widely used in heat exchange equipment, such as column tube heat exchanger, coil tube heat exchanger, serpentine tube heat exchanger, condenser, evaporator and conveying pipeline. Many nuclear power industries use titanium tubes as standard tubes for their units.

Titanium tubes are manufactured according to two national standards: GB/T3624-2010, GB/T3625-2007, according to different requirements and properties.
Supply grade: TA0, TA1, TA2, TA9, TA10, BT1-00, BT1-0, Gr1, Gr2

Note: "○" indicates the specifications that can be produced

For many years now, titanium has shown that it an indispensable material. It has become very valuable in the aircraft industry, chemical processing plants, gas and oil production, and many more.

Titanium can easily be fabricated, welded, and formed to make it useful in a number of industrial operations. Titanium tubes are an example of how titanium can be rendered to become functional today.
