Many nuclear power industries use titanium tubes as standard tubes for their units. Titanium tube is light in quality, high in strength and superior in mechanical properties. It is widely used in heat exchange equipment, such as tube heat exchanger, coil heat exchanger, serpentine tube heat exchanger, condenser, evaporator and conveying piping.
Titanium tube has plasticity: the elongation of high purity titanium tube can be up to 50-60%, section shrinkage can be up to 70-80%. Despite the low strength of high-purity titanium tube, but pure industrial titanium contains a small number of impurities and add alloying elements can significantly strengthen its mechanical properties, so that its strength can be compared with high strength. That is to say, pure industrial titanium tube, as long as it contains a small amount of interstitial impurities and other metal impurities, you can make it both high strength, but also has the appropriate plasticity.
Industrial pure titanium tube specific strength (strength to weight ratio) in the metal structure materials is very high, its strength and steel, but its weight is only 57% of steel.
Titanium tube is very heat-resistant, in the atmosphere at 500 ℃ can still maintain good strength and stability.
Titanium tube also has good low-temperature resistance, even at -250 ℃ under the ultra-low temperature, it still has a high impact strength, can be resistant to high-pressure anti-vibration.
Titanium tube corrosion resistance, which is due to its affinity for oxygen is particularly large, can generate a dense layer of oxidized film on its surface, can protect the titanium from medium corrosion. Therefore, titanium in acidic, alkaline, neutral saline solution and oxidizing media with good stability, than the existing stainless steel and other non-ferrous metals have good corrosion resistance.
