Product Specification

Titanium Elbow Titanium Gr2 OD76*ID5.5 Titanium Seamless Tube Titanium Round Tube 

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.
