Characteristics and application of industrial pure titanium tube
Titanium has plasticity. The high-purity titanium has an elongation of 50 to 60% and a reduction in area of 70 to 80%. Despite the low strength of high-purity titanium, pure industrial titanium contains a small amount of impurities and the addition of alloying elements can significantly enhance its mechanical properties, so that its strength can be compared with high strength. This means that industrial pure titanium tubes can have both high strength and proper plasticity as long as they contain a small amount of interstitial impurities and other metal impurities.
The specific strength (strength to weight ratio) of industrial pure titanium pipes is very high in metal structural materials. Its strength is comparable to that of steel, but its weight is only 57% of that of steel. In addition, the titanium tube has a high heat resistance and maintains good strength and stability in an atmosphere of 500 °C. The titanium tube also has good low temperature resistance, and even at an ultra-low temperature of -250 °C, it has high impact strength and can withstand high pressure and vibration.
Another remarkable feature of the industrial pure titanium tube is its high corrosion resistance. This is because it has a particularly high affinity for oxygen and can form a dense oxide film on its surface to protect the titanium from the medium. Therefore, titanium has excellent stability in acidic, alkaline, neutral saline solutions and oxidizing media, and is superior in corrosion resistance to existing stainless steels and other non-ferrous metals. Industrial pure titanium tubes are widely used. At present, industrial pure titanium tubes are not only used in aerospace and aviation industries, but also widely used in many industrial sectors such as chemical, petroleum, light industry and power generation.
Because pure industrial titanium tube has many excellent characteristics such as light weight, high strength, strong heat resistance and corrosion resistance, it is known as “the metal of the future” and is a new type of structural material with great development prospects.
