Titanium tube has light weight, high strength and superior
mechanical properties. It is widely used in heat exchange
equipment, such as tube and tube heat exchanger, coil heat
exchanger, snake-like tube heat exchanger, condenser, evaporator
and transportation pipeline. Many nuclear power industries use
titanium tubes as standard tubes in their units.
Titanium alloy has high strength and small density, good mechanical
properties, good toughness and corrosion resistance. In addition,
titanium alloy process performance is poor, cutting difficult, in
hot processing, very easy to absorb hydrogen, oxygen, nitrogen,
carbon and other impurities. There are poor wear resistance and
complex production process. Industrial production of titanium began
in 1948. The need of the development of aviation industry makes the
titanium industry develop at an average annual growth rate of about
8%. At present, the annual output of titanium alloy processing
materials in the world has reached more than 40,000 tons, and
nearly 30 kinds of titanium alloy brands. The most widely used
titanium alloys are Ti-6Al-4V(TC4),Ti-5Al-2.5Sn(TA7) and industrial
pure titanium (TA1, TA2 and TA3).
Titanium alloy is mainly used in aircraft engine compressor parts,
followed by rocket, missile and high-speed aircraft structural
parts. By the mid-1960s, titanium and its alloys were already in
general industrial use, making electrodes for industrial
electrolysis, condensers for power stations, heaters for petroleum
refining and seawater desalination, and pollution control devices.
Titanium and its alloys have become a kind of corrosion - resistant
structural material. In addition, it is also used to produce
hydrogen storage materials and shape memory alloys.
China began titanium and titanium alloy research in 1956; In the
mid 1960s, industrial production of titanium materials began and
TB2 alloy was developed.
Titanium alloy is a new important structural material used in
aerospace industry. Its specific gravity, strength and service
temperature are between that of aluminum and steel, but it has high
specific strength and excellent seawater corrosion resistance and
ultra-low temperature performance. In 1950, the U.S. first used the
f-84 fighter-bomber as the rear fuselage heat shield, air hood,
tail hood and other non-bearing components. Since the 1960s, the
use of titanium alloy has moved from the rear fuselage to the
middle fuselage, partially replacing structural steel in making
important load-bearing components such as enclosures, beams, flaps
and slide rails. The use of titanium alloys in military aircraft
has increased rapidly, reaching 20 to 25 percent of the weight of
aircraft structures. Since the 1970s, civil aircraft began to use
numerous titanium, such as Boeing 747 passenger aircraft with
titanium amount of more than 3640 kilograms. Aircraft with Mach
numbers less than 2.5 use titanium mainly in place of steel to
reduce structural weight. For example, in the US SR-71
high-altitude high-speed reconnaissance aircraft (flying Mach
number of 3, flying at 26,212 meters), titanium accounted for 93%
of the weight of the aircraft structure, known as "titanium"
aircraft. When the thrust-weight ratio of the aero-engine is
increased from 4 ~ 6 to 8 ~ 10, and the outlet temperature of the
compressor is correspondingly increased from 200 ~ 300 °C to
500 ~ 600 °C, the original low-pressure compressor plate and
blade made of aluminium must be changed to titanium alloy, or
titanium alloy instead of stainless steel to make high-pressure
compressor plate and blade, in order to reduce the structural
weight. In the 1970s, the amount of titanium alloy used in
aero-engines generally accounted for 20% ~ 30% of the total weight
of the structure. It was mainly used to manufacture compressor
parts, such as forged titanium fans, compressor plates and blades,
cast titanium compressor casing, intermediate casing, bearing
housing, etc. The spacecraft mainly uses the high specific strength
of titanium alloy, corrosion resistance and low temperature
resistance performance to manufacture a variety of pressure
vessels, fuel storage tank, fasteners, instrument straps, frame and
rocket shell. Earth satellites, lunar modules, manned spacecraft
and space shuttles also use titanium plate welds.
