Original Title: Development and Application of Titanium Welded Pipe in China Titanium has been processed into various forms and forms of products used in various fields because of its excellent corrosion resistance and high specific strength. Titanium welded pipe is a relatively unique product form in the titanium family, which is made of titanium and titanium alloy coiled strip or wide plate by rolling into pipe shape and then welding. 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 many years. The development of titanium welded pipe in China started late and developed slowly in the early stage. In the early stage of titanium welded pipe development, although China introduced a complete small-diameter titanium welded pipe automatic production line from abroad, the domestic production of titanium welded pipes was inhibited because the raw material titanium coil and strip for domestic production of titanium welded pipes was completely dependent on imports at that time, and the price was relatively expensive; in addition, due to multiple difficulties in technology introduction and raw material procurement,titanium tubing price, domestic titanium welded pipes have not really had the capacity of mass production. In the past ten years, due to the major breakthrough in the production technology of titanium coil and strip in China, the titanium welded pipe industry in China 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 greatly improved compared with before. Application of Titanium Welded Pipe [2] At present,titanium bar gr5, titanium welded pipe has become the preferred pipe to replace stainless steel pipe, copper-nickel alloy pipe and titanium seamless pipe in many industries.

Application in seawater desalination In the past, most of the condenser tubes in seawater desalination equipment in China were made of copper alloy tubes, but their corrosion resistance was poor, and with the increase of copper price, the cost increased a lot. Later, Titanium welding pipe ,titanium round bar, stainless steel welded pipes with good corrosion resistance gradually replaced copper alloy pipes and became the main material for condenser pipes. The application of titanium welded pipe is also gradually expanding, and many countries are more willing to use titanium welded pipe with high cost but better corrosion resistance. 2. Application in power industry Both thermal power plants and nuclear power plants need a large number of heat exchanger devices, such as condensers, condensers, heat exchangers and so on. Most of these power plants use seawater as cooling medium, and titanium welded pipes with corrosion resistance and long maintenance cycle are generally used as cooling pipes. 3. Application in petrochemical industry In some fields of petrochemical industry, such as the cooler used in the process of crude oil refining and p-xylene production, it is not suitable to use stainless steel welded pipe, which is very prone to pitting corrosion, so titanium welded pipe must be used. In the chemical industry, many corrosive devices can only use titanium welded pipe to ensure the normal operation of the equipment and reduce the time and frequency of maintenance. 4. Sports industry Stainless steel welded pipe is mainly used in sports equipment, but titanium welded pipe is also widely used in sports goods, such as golf clubs, bicycle frames and so on. 5. Application in aerospace industry In the field of aerospace, titanium welded pipe has incomparable advantages compared with stainless steel welded pipe. It can not only reduce the weight of the aircraft, but also prolong the service life and reduce the maintenance time. In a word, the practicability of titanium welded pipe is very high, but the price is expensive. With the progress of production process and technology, the price of titanium welded pipe will be gradually reduced and accepted by the majority of users.
