Many nuclear power industries use titanium tubes as the standard tubes for their units. Titanium tube has light weight, high strength and excellent mechanical properties. It is widely used in heat exchange equipment, such as tubular heat exchanger, coil heat exchanger, serpentine heat exchanger, condenser, evaporator and transmission pipeline.

Titanium tube has plasticity: the elongation of high-purity titanium tube can reach 50-60%, and the reduction of area can reach 70-80%. Although the strength of high-purity titanium tube is low, pure industrial titanium containing a small amount of impurities and adding alloy elements can significantly strengthen its mechanical properties, making its strength comparable to high strength. That is to say, as long as there is a small amount of interstitial impurities and other metal impurities in the industrial pure titanium tube, it can have both high strength and proper plasticity.

The specific strength (strength to weight ratio) of industrial pure titanium pipe 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.

The titanium tube has strong heat resistance and can still maintain good strength and stability in the atmosphere of 500 ℃.

Titanium tube also has good low temperature resistance. Even at the ultra-low temperature of - 250 ℃, it still has high impact strength and can withstand high pressure and vibration.

Titanium tube has strong corrosion resistance, which is due to its strong affinity for oxygen, which 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 brine solution and oxidizing medium, and its corrosion resistance is better than that of existing stainless steel and other non-ferrous metals.
