We need to know the characteristics of titanium before using it. First, titanium has low density, which is half of stainless steel, so the weight of titanium is only half of stainless steel with the same volume, and it greatly reduces the weight. Second, titanium has better corrosion resistance to salt water (sea water) than copper. The titanium alloy materials such as Ti-3Al-2.5V, Ti-6Al-4V have the above advantages, and they also have higher strength and hardness.
Titanium tube is a metal material with high strength, hardness and corrosion resistance, which is widely used in aerospace, chemical corrosion prevention, health care, marine engineering equipment, refrigeration and heat transfer, bicycle and wheelchair frames, etc.
With the development of science and technology,is used more and more widely in many fields.
1. Aerospace field
Titanium tube used in aerospace field must have high strength and hardness, good creep resistance, high tensile strength at high temperature, and also certain corrosion resistance. The main titanium alloy material used is Grade 9(Ti-3Al-2.5V). AMS 4943, AMS4944, AMS4945 standards are implemented.
2. Chemical corrosion prevention field
Titanium tube can be used in acid and alkali environment, but not usable in sulfuric and nitric acid environment.
Chlor-alkali industry specializes in producing chlorine gas and caustic soda by electrolyzing salt aqueous solution. As the earliest, chemical industry that uses titanium, it has a history of more than one hundred years. The main titanium equipment used in chlor-alkali production is metal anode electrolytic cell, ion-film electrolytic cell, tubular wet chlorine cooler, refined brine preheater, dechlorination tower, chlor-alkali cooling scrubber, vacuum dechlorination pump and valve, etc.
Titanium tube can be used in the temperature of -50℃~+250℃. but cannot be used in higher temperature and extremely cold environment. Commercial pure titanium is the main material used.
3. Health care field
Since titanium tube is harmless to human body, so it is applicable to produce ventilator and breathing tube. Medical titanium is a metal which has much better antibacterial performance than stainless steel, so titanium tube is currently recognized internationally as the most ideal medical device material.
In addition, titanium is widely used in medical fields, including the production of heart valves, cardiac pacemakers and other medical devices, and also surgical materials due to its characteristic of harmless to human body.
4. Marine engineering field
Marine engineering mainly refers to the construction of ocean facilities, including sea vessels, undersea tunnels and various drilling platforms. Titanium has good corrosion resistance, high strength and good temperature resistance. As one of the main metal in marine engineering equipment, it has a wide range of applications.
Thin-walled titanium tube has many uses in desalination, including ships, deep-sea probes, offshore oil and gas exploration, and various seawater pipelines.
5. Refrigeration and heat transfer field
Titanium tube refrigerating system can be used in various industries, such as seafood culture constant temperature, condensers, heat exchangers, swimming pool heat pump system. Although titanium has lower thermal conductivity than copper, it has better resistance to saltwater corrosion, so it can greatly extend the service life of the equipment.
6. Bicycle and automobile field
Titanium alloy is currently recognized internationally as the most ideal material for high-grade bicycles. Titanium alloy is characterized by lightweight, high strength, good elasticity, good impact resistance, good fatigue performance, good corrosion resistance, and never rust. Therefore, it is widely used in bicycles, especially racing cars, which requires lightweight, good stiffness and good impact performance, in order to improve speed and reduce physical exertion over long distances. It is also widely used in exhaust pipe system of automobiles.
