Because of its excellent corrosion resistance and extreme specific strength, titanium has been processed into various forms and forms of products used in various fields. Titanium Pipe is a relatively rare product form in the titanium family. It is made of titanium and titanium alloy coil or wide sheet rolled into a tube shape and welded.
Development of Titanium Welded Pipe Industry in China [1]
Due to the constraints of raw materials and processing technology, the production technology of titanium welded pipe has been in the hands of Japan, the United States and other developed countries for numerous years. The development of titanium welded pipe in China started late, and the early development is moderate.
In the early stage of the development of titanium welded pipes, although China introduced a complete tiny-diameter automatic production line of titanium welded pipes from abroad, the domestic production of titanium welded pipes was inhibited because the raw material of titanium coil for the production of titanium welded pipes was entirely dependent on imports at that time, and the price was relatively steep. In addition, due to multiple difficulties in technology introduction and raw material procurement, domestic titanium welded pipe has not been truly capable of mass production.
In the past ten years, due to the domestic production technology of titanium coil having made a major breakthrough, China’s titanium welded pipe industry has developed rapidly, and even achieved batch export. It can be seen that the production process and quality level of domestic titanium welded pipe have been considerably improved compared with before.
Application of titanium welded pipe [2]
At present, titanium welded pipes have become numerous industries to replace stainless steel pipes, copper nickel alloy pipes, titanium seamless pipes of choice.
1. Application in seawater desalination
In the past, most condensate tubes used in seawater desalination equipment were copper alloy tubes, but its corrosion resistance is poor, and with the increase of copper price, the cost has increased a lot.
Later, stainless steel welded pipe with excellent corrosion resistance gradually replaced copper alloy pipe as the main condensate pipe materials. And the application of titanium welded pipe is also gradually developed. Many countries are more willing to use high cost but better corrosion resistance of titanium welded pipe.
2, the application in the power industry
Both thermal power plants and nuclear power plants need to use a large number of heat exchanger devices, such as condensers, condensers, heat exchanger and so on. Most of these power plants use seawater as the cooling medium, and typically adopt corrosion resistant and lengthy maintenance cycle titanium welded pipe as the cooling pipe.
3. Application in petrochemical industry
In some fields of the petrochemical industry, such as the cooler used in the process of crude oil refining and p-xylene production, it is not suitable for stainless steel welded pipe, extremely easy to pitch, must use titanium welded pipe.
In the chemical industry, numerous corrosive devices can only use titanium welded pipe to ensure the normal operation of equipment, reducing the time and frequency of maintenance.
4. Sports industry
The application of stainless steel welded pipe in sports equipment occupies the main position, but the application of titanium welded pipe in sports goods is also extremely wide. At present, there are more applications for golf clubs, bicycle racks and so on.
5. Applications in the aerospace industry
In the field of aeronautics and astronautics, titanium welded pipe has incomparable advantages compared with stainless steel welded pipe. It can not only reduce the weight of the aircraft, but also extend the service life and reduce maintenance time.
In short, titanium welded pipe is extremely superior in practicality, but the price is also costly. With the progress of production process and technology, the price of titanium welded pipe will be gradually reduced, accepted by the majority of users.
