Titanium alloy tubes are tubes made of titanium alloys. Titanium tubes have high mechanical properties and excellent stamping properties, and can be welded in various forms. The strength of the welded joint can reach 90% of the strength of the base metal, and the cutting performance is good. Titanium tubes have high corrosion resistance to chlorides, sulfides, and ammonia. Titanium has higher corrosion resistance in seawater than aluminum, stainless steel, and nickel-based alloys. Titanium also has strong water impact resistance.
Characteristics of titanium tubes
1. Titanium tubes have plasticity. The elongation of high-purity titanium tubes can reach 50-60%, and the cross-sectional shrinkage can reach 70-80%. Although high-purity titanium tubes have low strength, a small amount of impurities, and the addition of alloying elements in pure industrial titanium can significantly enhance its mechanical properties, making its strength comparable to high steel. That is to say, as long as industrial pure titanium tubes contain a small amount of interstitial impurities and other metal impurities, they can have both high strength and appropriate plasticity.
2. The specific strength (strength-to-weight ratio) of industrial pure titanium tube is very high among metal structural materials. Its strength is equivalent to that of steel, but its weight is only 57% of that of steel.
3. The Titanium tube has strong heat resistance and can still maintain good strength and stability in an atmosphere of 500℃.
4. The Titanium tube also has good low-temperature resistance. Even at an ultra-low temperature of -250℃, it still has high impact strength and can withstand high pressure and vibration.
5. The Titanium tube has strong corrosion resistance. This is because it has a particularly strong affinity for oxygen and can form a dense oxide film on its surface, which can protect titanium from medium corrosion. Therefore, titanium has good stability in acidic, alkaline, neutral salt solutions and oxidizing medium, and has better corrosion resistance than existing stainless steel and other non-ferrous metals.
Specific applications of titanium tubes
Titanium tubes are lightweight, high in strength, and have excellent mechanical properties. The characteristics of titanium tubes are widely used in heat exchange equipment, such as shell-and-tube heat exchangers, coil heat exchangers, serpentine heat exchangers, condensers, evaporators, and pipelines. Specifically:
1. Chemical industry
The types of equipment have developed from small and single to large and diversified. According to the chemical industry, the application of titanium tube equipment has expanded from the initial soda ash and caustic soda industry to the entire chemical industry. The annual use of titanium tubes in the chemical industry will exceed 1,500 tons. After the 1970s and 1980s, China's vacuum salt-making enterprises gradually began to use titanium tube metal materials to manufacture equipment, resulting in a significant improvement in equipment corrosion.
2. Petroleum refining
The sulfides, chlorides, and other corrosive agents in petroleum processing products and cooling water are seriously corrosive to the refining equipment, especially the atmospheric and vacuum tower top condensing equipment in the low-temperature light oil part during the petroleum refining process. The equipment corrosion problem has become one of the prominent problems plaguing the refining industry. In recent years, the United States, Japan, and other countries have introduced titanium tube equipment into these highly corrosive links and achieved good results.
3. Automobile industry
The application of titanium tube characteristics in racing cars has a history of many years. The lightweight and high-strength properties of titanium tubes have long been the focus of automobile manufacturers. At present, almost all racing cars use titanium tubes (handheld spectrometers), and Japanese cars use titanium. The production of titanium tubes has exceeded 600 tons. With the development of the global automobile industry, the use of titanium tubes for automobiles is still increasing rapidly.
4. Sports goods
Titanium tubes have the characteristics of high strength, light weight, and corrosion resistance. They are very suitable for making high-quality irons, golf clubs, bicycle frames, and other sports equipment.
5. Medical field
Titanium tubes have good biocompatibility and are not easy to cause humans. At the same time, they have excellent corrosion resistance and strength, and have gradually become the preferred material in the medical field. The characteristics of titanium tubes can be used to make artificial joints, dental implants, skull repair materials, internal stents, and other medical devices.
6. Aerospace field
Titanium tubes have excellent corrosion resistance and corrosion resistance, and can be used to produce various structures and components, such as engine components, cylinders, landing gear, seat frames, oxygen cylinders, rocket sealing structures, etc.
7. Marine engineering
In the environment of huge water pressure in the deep sea, the corrosion resistance of titanium tubes has become a necessary condition for marine engineering. It is widely used in the production of submarine pipelines, submarine oil wells, support structures of marine wind turbines, marine biological resource survey equipment, etc.
