Can Large Diameter Titanium Tubes Be Used At Low Temperatures?

Can large diameter titanium tubing be realized for low temperature use? Titanium, as a rare metal element, has much more to offer than what we see, and power generation equipment in general, and the lower temperature side of its thermal cycle in particular, provides an ideal environment for titanium to be used.
It is possible to develop a new type of titanium alloy tube applied at higher lower operating temperatures, compared with the developed high-strength low-temperature titanium alloy tube, it will have greater potential to save metal and improve efficiency, the future goal is to develop a use of titanium tubes with a temperature of up to 650 ° C. This alloy can be used for high-pressure turbine discs, and commonly used in the base of the discs compared to the weight can be reduced by 20%.
However, with the increase in operating temperature will inevitably bring more new problems, such as surface oxidation, long-term stability of high-volume metallurgical production, frictional corrosion, fire hazards and hot salt stress corrosion. Some of these problems can be solved by means of surface coatings or surface treatments, for which research is being actively pursued.
