Many nuclear power industries use titanium tubes as their unit standard. Titanium tube has light weight, high strength, and excellent mechanical properties. It is widely used in heat exchange equipment, such as tubular heat exchangers, coil heat exchangers, serpentine heat exchangers, condensers, evaporators, and transportation pipelines.
Titanium tubes have plasticity: the elongation of high purity titanium tubes can reach 50-60%, and the reduction of area can reach 70-80%. Despite the low strength of high purity titanium tubes, pure industrial titanium containing a small amount of impurities and adding alloying elements can significantly enhance its mechanical properties, making its strength comparable to high strength. This means that industrial pure titanium tubes can have both high strength and appropriate 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 tubes is very high among metal structural materials, and its strength is equivalent to that of steel, but its weight is only 57% of that of steel.
Titanium tubes have strong heat resistance and can maintain good strength and stability in an atmosphere of 500 ℃.
Titanium tubes also have excellent low temperature resistance. Even at ultra low temperatures of - 250 ℃, they still have high impact strength and can withstand high pressure and vibration.
Titanium tubes have strong corrosion resistance due to their strong affinity for oxygen, which can form a dense oxide film on their surface, protecting titanium from medium corrosion. Therefore, titanium has good stability in acidic, alkaline, neutral saline solutions and oxidizing media, and has better corrosion resistance than existing stainless steel and other nonferrous metals.
