The density of titanium alloy is generally about 4.51g/ cubic centimeter, only 60 of steel, the strength of pure titanium is close to the strength of ordinary steel, some high strength titanium alloy exceeds the strength of many alloy structural steel. Therefore, the specific strength (strength/density) of titanium alloy is much higher than that of other metal structural materials, as shown in Table 7-1. It can produce components with high unit strength, good rigidity and light weight. At present, titanium alloy is used for engine components, skeleton, skin, fasteners and landing gear.
High thermal strength
The use temperature is several hundred degrees higher than aluminum alloy, can still maintain the required strength at moderate temperature, can work for a long time at 450500 temperature these two titanium alloys still have high specific strength in the range of 150500, and aluminum alloy at 150 than the strength decreased significantly. Titanium alloys operate at temperatures up to 500, while aluminum alloys operate below 200.
Good resistance to corrosion
The corrosion resistance of titanium alloy is much better than that of stainless steel when working in humid atmosphere and seawater medium. Resistance to pitting corrosion, acid corrosion, stress corrosion is particularly strong; Excellent corrosion resistance to alkali, chloride, chlorine organic articles, nitric acid, sulfuric acid and so on. But titanium has poor corrosion resistance to reducing oxygen and chromite medium.
Good low temperature performance
Titanium alloy can keep its mechanical properties at low temperature and ultra low temperature. Titanium alloys with good low temperature performance and very low gap elements, such as TA7, can maintain certain plasticity at -253. Therefore, titanium alloy is also an important low temperature structural material.

Titanium alloy tubes can be divided into three categories according to phase composition: α Alloy( α+β) Alloy and β alloy
1. α Stability of alloy containing a certain amount α The element of phase, in equilibrium, is mainly composed of α Phase composition. α The alloy has small specific gravity, good thermal strength, good weldability and excellent corrosion resistance. Its disadvantage is low strength at room temperature. It is usually used as heat-resistant and corrosion-resistant materials. α Alloys can usually be divided into complete alloys α Alloy (Gr7), near α Alloy (ti-8al-1mo-1v) and alloy with a small amount of compounds α Alloy (Ti-2.5Cu).
2. ( α+β) Stability of alloy containing a certain amount α Phase harmony β Phase elements, and the microstructure of the alloy in equilibrium is α Phase harmony β Phase. ( α+β) The alloy has medium strength and can be strengthened by heat treatment, but its weldability is poor. ( α+ β) Alloys are widely used, and the output of Ti-6Al-4V Alloy accounts for more than half of all titanium materials.
3. β The alloy contains a large amount of stable β Phase elements can be used at high temperature β All phases were retained to room temperature. β Alloys can usually be divided into heat treatable alloys β Alloy (metastable) β Alloy and near metastable β Alloy) and thermal stability β Alloy. Heat treatable β The alloy has excellent plasticity in quenched state, and the tensile strength can reach 130 ~ 140kgf / mm2 by aging treatment. β Alloys are usually used as high strength and high toughness materials. The disadvantages are large ratio, high cost, poor welding performance and difficult machining.

Titanium seamless pipe for heat exchanger
The grade 2 titanium tube consists of commercial pure titanium or Unalloyed titanium. The oxygen content of grade 2 is standard. ASTM b861 GR 2 pipes can be easily welded. It also has excellent strength and ductility. The natural strength of metal is used for applications requiring very high strength, and the corrosion resistance is used for long-term appliances. Although most use cases are in industrial standards, titanium grade 2 seamless pipes can also be used in aesthetic and home applications. Due to the cost of raw materials and production costs, the cost is very high. The content of titanium in commercial pure CP grade 2 titanium welded pipe exceeds 99%. It can be cold drawn into titanium seamless pipe or hot rolled into welded pipe. They are used in high temperature applications, such as titanium 2-stage exhaust pipes, which can maintain their shape due to their high thermal conductivity, low thermal expansion and high oxidation resistance at high temperatures.

Tube plate material: according to the need to use different environment, the use of different materials, carbon steel material generally use Q345R container plate, such as first and second pressure vessels, no corrosive medium flow, the use of carbon steel composite plate. In the case of strong acid, high pressure and high temperature, nuclear energy and other environments, stainless steel, 16 manganese, titanium alloy and other corrosion-resistant materials are needed. The application of new synthetic materials brings new vitality to tube-sheet products. With high pressure environment, but also to the case of corrosion resistance, considering the use of cost, generally choose high strength steel and corrosion resistant materials of composite material structure.
