The Development And Application Of Titanium Alloy Welded Pipes in China

Titanium is processed into various forms and forms of products used in various fields due to its excellent corrosion resistance and high specific strength. Titanium welded pipe is a relatively unique product form in the titanium family. Titanium and titanium alloy coiled strips and wide plates are rolled and welded into a pipe shape.

The development of China's titanium welded pipe industry

Due to the constraints of raw materials and processing technology, the production process of titanium welded pipe for many years has been mastered in Japan, the United States and other developed countries. China's titanium welded pipe development started late, the early development is slow.

In the early stage of the development of titanium welded pipe, China introduced a complete automatic production line of small diameter titanium welded pipe from abroad, but at that time, the domestic production of titanium welded pipe raw materials titanium coil and strip is completely dependent on imports, the price is high, so inhibit the domestic production of titanium welded pipe, in addition, due to the introduction of technology and raw material procurement and many other difficulties, the domestic titanium welded pipe really does not have the ability of mass production.

Application of titanium welded pipe

At present, titanium welded pipe has become the first choice to replace stainless steel pipe, copper-nickel alloy pipe and titanium seamless pipe in many industries.

1,Application in seawater desalination

In the past, China's desalination equipment in the condensate pipe material is mostly copper alloy tube, but its corrosion resistance is poor, and with the rise in copper prices, the cost also increased a lot.

Subsequently, stainless steel welded pipe with good corrosion resistance gradually replaced copper alloy pipe and became the main material of condenser pipe. The application of titanium welded pipe is also gradually launched, many countries prefer to use high cost but better corrosion resistance of titanium welded pipe.
2, in the power industry

Whether it is thermal power plants or nuclear power plants, need a large number of heat exchange devices, such as condensers, condensers, heat exchangers and so on. These power plants mostly use seawater as the cooling medium, and generally use corrosion-resistant, long maintenance cycle of titanium welded pipes as cooling pipes.

3,Application in the petrochemical industry.

In some areas of petrochemical industry, such as crude oil refining, xylene production process used in the cooler, is not very suitable for stainless steel welded pipe, prone to pitting corrosion, must use titanium welded pipe.

In the chemical industry, many corrosive devices only use titanium welded pipe to ensure the normal operation of the equipment, reduce the time and frequency of maintenance.

4, sports industry

Stainless steel welded pipe in the application of sports equipment accounted for the main position, but titanium welded pipe in sporting goods is also widely used, the current application of more golf clubs, bicycle frames and so on.
