As a rare metal element, titanium has much more properties than meets the eye. General power generation equipment, especially the side with low thermal cycle temperature, provides an ideal environment for titanium.

Likely to develop a higher operating temperature application a new type of titanium tube, compared with the high strength and low temperature titanium pipe has been developed, it will be to save and improve the efficiency of metal side has more potential, use the next goal is to develop a temperature can reach 650 ℃ of the titanium alloy tube, this alloy can be used for high pressure turbine wheel, Compared with the common base wheel, the weight can be reduced by 20%.

However, with the increase of the working temperature of titanium alloy tube is bound to bring more new problems, such as surface oxidation, long-term stability of mass metallurgical production, friction corrosion, fire risk and hot salt stress corrosion. Some problems can be solved by means of surface coating or surface treatment, and research in this area is being actively carried out.
