Application of titanium in the chemical industry

Titanium used in petroleum, chemical and other sectors

Petrochemical reactors, pressure vessels, heat exchangers, separators, piping, distillation tower condenser lining and so on.
Chemical industry distillation columns, reactors, pressure vessels, heat exchangers, filters, measuring instruments, turbine blades, pumps, valves, pipes, chlor-alkali production electrodes, synthetic lining tower, other acid-resistant equipment lining.
Paper Industry blender, bleaching tower, heating bath, the reaction tower piping.
Bleacher continuous textile industry, a distillation column, the reaction vessel, a condenser, heat exchange tubes, centrifuge, spinneret, valves, pumps.
Metallurgical Industry steel getter alloy additives, superconducting alloy material, electrolytic high purity metal (e.g., sodium, nickel, cobalt) of the cathode plate and the plating bath and the like.
Desalination and power plant heat exchangers, condensers, water heaters, pipes, other contact with seawater equipment.
Naval vessels housing industry, decks, valves, wing, propeller boats, drive shaft, the steam engine, the deep submarine pressure tanks, development of marine equipment.
Other titanium industrial bar ultrahigh vacuum pumps, medical and orthopedic instruments, artificial joints, pharmaceutical and food industry equipment.
Second, the titanium in the aviation industry application specific strength of titanium and its alloys (important than strength) is high in the metal structure of the material, its strength steel equivalent, but its importance is only 57% of the steel. In addition, the heat resistance of titanium and its alloys are strong, in the atmosphere of 500 ℃ can still maintain good strength and stability, but also short-term operating temperature even higher. The aluminum 150 ℃, stainless steel at 310 ℃ to lose their mechanical properties. When the aircraft missiles, rocket-speed flight, the engine and the surface temperature is very high, aluminum was not competent, the application of titanium alloy is very appropriate. It is because when the titanium and its alloys have high strength, light weight, heat and strong overall excellent performance, aircraft used instead of other metals in it, not only to extend the service life of the aircraft, but also can reduce their weight, thus greatly improve its flight performance. Therefore, titanium is one of the aviation industry and the aerospace industry's most promising structural materials. Titanium and its alloys. Mach 2 aircraft that its engine with titanium increased, but also part of the body needs titanium. Greater than Mach 3.5 aircraft, the engine inlet temperature is very high, it is not a high impact strength, can withstand high pressure, anti-vibration. Therefore, titanium round bar and its alloys in rockets, missiles and spacecraft only for the manufacture of the engine casing and structural components, and for the manufacture of pressure vessels, such as high-pressure gas cylinders, cryogenic liquid fuel tanks. In addition, titanium and its alloys in nuclear reactors and weapons have military applications.
