Development trend of titanium pipe in China

1, China's titanium industry background and titanium pipe application field

From the United States in 1948 with the production of titanium sponge 2T magnesium reduction method, titanium industry ushered in the era of human; although the real industrialization began in 1950s, but the titanium with light weight, high strength, corrosion resistance, low thermal conductivity, good temperature resistance, welding, no magnetism, good biocompatibility and other excellent the characteristics, has been widely concerned; but because of the high production cost, large range of hindered titanium material in the field of industrial use. In recent years, the development of science and technology and the progress in the production technology of making titanium material can be processed into various products used in many areas, after more than half a century of development, has become an indispensable material of titanium aerospace, marine, petroleum and chemical industry, medical and other materials.

As can be seen from the data in table 1......

2, the production process and product characteristics of titanium seamless pipe

Because the performance of pure titanium is similar to that of common steel, the production process of titanium tube is similar to that of steel tube. However, the application of titanium tube has been restricted by cost. In recent years, with the change of the market, the increase in the number of titanium manufacturers, leading to the gradual decline in the price of titanium tubes, while the economic applicability of titanium tubes are gradually recognized, which makes the further expansion of the application of pipe......

The existing production of titanium seamless pipe, mature technology, product supply stability, but for the special requirements of the pipe, the difficulty of titanium seamless tube production, such as titanium and titanium alloy thin-walled tube, super long titanium tube length of more than 14m; at the same time, titanium seamless tube production need more tools, tools, equipment complex, lead to the manufacturers production capacity is limited. The production cycle is longer, can not meet the market demand for a large number of thin walled tube, low cost, long tube tube.

3, the production process and product characteristics analysis of titanium pipe

Based on the shortcomings of the above titanium seamless pipe, titanium welded pipe. At present, the international large-scale titanium pipe company is the Steel Corp of Japan and Kobe steel company, France Valtimet company, VSMPO company in Russia etc.. In the middle of the 1980s, Baoji nonferrous metal processing factory imported titanium pipe production line from the United states. Since then, the history of China's production of titanium welded pipe can not be. The main factor that restricts the development of our country's titanium welded pipe is the production technology of titanium. Until 2005, baotaigufen initiated by the French Valtimet company to provide technical support, the United States Timet company titanium strip coil material, three joint venture .

Titanium welded pipe with the stable supply of titanium, the cost of further decline, more intense competition. Data shows that since 2008, the expansion of the expansion of titanium sponge production capacity, to speed up China's titanium strip production line with the pace of construction, raw material supply situation changed rapidly and the expected Chinese plan to stimulate the construction of nuclear power in titanium, since 2008, China unleashed a strong titanium pipe production line investment boom...... it can be predicted that the cost of titanium pipe advantage, will promote the future of titanium pipe substitute seamless titanium.

4, the development prospects of other titanium tube

Production and development of 4.1 hot extruded titanium alloy tubes

With the development of economy, the demand for oil and gas drilling and exploitation has been accelerated, and the demand for large diameter titanium alloy tubes, such as oil wells, geothermal and natural gas pipelines, has increased. At present, the United States will (48-610) Ti6Al4V-Ru alloy tube mmx26mmx2600mm for geothermal and offshore pipeline, the American company RMI 650mmx (22-25) mmx350000mm long Ti3Al2.5V-Ru alloy tube used for offshore oil exploitation; Norway Beihai drilling platform riser is used in Ti6Al4V Eli 600mmx25mmx15000mm alloy tube......

Development and production of 4.2 titanium tube

The development process of international titanium tube is relatively slow, only the United States, using extrusion and stretching method, produce square, rectangle, triangle, oval shape titanium tube, become the world's only a production of titanium tube company. Because of the obvious anisotropy, large deformation resistance, poor plasticity, the elongation characteristics and difficulties in forming and springback of forming of titanium alloy at room temperature, the bending process of titanium material is very complex, because of this reason, limited the development of titanium tube. Application of titanium tube......

5. Conclusion

On the one hand, with the technological transformation and upgrading of titanium sponge factory, the efficiency will be further improved, the cost of titanium sponge will also be reduced, which directly led to the reduction of the cost of titanium processing materials, and promote the market application of titanium. On the other hand, the further improvement of titanium recovery production line, the cost of titanium materials will be reduced, compared to other materials, titanium pipe prices will be more competitive advantage......

In the titanium pipe, with a titanium belt production line, improve the production process of titanium strip, strip product quality improved steadily, which reduced the production cost of titanium pipe itself, the price is stable; with the improvement of the quality of the welding of titanium tube, titanium pipe will further expand the market share, and gradually replace titanium seamless pipe.
