With the rapid development of China's economy, the consumption of stainless steel pipes in China is also growing rapidly. During the period from 1990 to 2008, the annual average growth rate of apparent consumption of stainless steel pipes in China was 23.4%, which was 4 times of the international growth rate during the same period (the average annual growth rate of the apparent consumption of international stainless steel pipes during the same period was 6%). The rapid growth in the consumption of stainless steel pipes in China has stimulated the rapid development of the domestic stainless steel pipe industry. With the support of relevant government policies, the output of stainless steel pipes in China has grown from more than 200,000 tons in 1998 in a short period of time of less than ten years. By the 2006 level of 5 million tons, the production capacity will have increased to more than 10 million tons.
At present, in the consumption structure of stainless steel pipes in China, in addition to individual high-end products such as ultra-wide and ultra-thin specifications that still rely on imports, the low-end and middle-end products can basically be self-sufficient, and the situation in which stainless steel pipe consumption is completely dependent on imports has been greatly improved. The volume is also rapidly expanding. According to statistics, in 2009 China's actual output of stainless steel pipe was approximately 5.1 million tons, the growth rate was approximately 60%, the import volume fell to 2.6 million tons, and the export volume increased to 600,000 tons.
Power station boiler tubes, heat transfer tubes, according to survey, a 600,000 kilowatt boiler with a variety of specifications of 455 tons of steel tubes, each 600,000 kilowatts of nuclear power plants require the use of evaporator "U" shaped heat transfer tubes 100 tons. In addition, there are a large number of precision reactors and control rods for reactor internals, nuclear fuel tubes, and the like. The 304 stainless steel pipe is currently in the boiler's important pressure-receiving parts - superheater and reheater parts of the coal-fired thermal power unit in China. Large domestic steel mills have already developed the seamless steel pipe blank for domestic super-supercritical boilers. Blank new products have reached the international advanced level of similar products and can replace imports. Domestic Huaxin Lihua, Huzhou Jiuli and other companies have also developed seamless steel tubes for super (super) critical power station boilers, and also lay the foundation for boiler tube applications in the nuclear power industry. The foundation. At present, the "U" shape evaporator of nuclear power plants is basically dependent on imports. The stainless steel super long tube in the boiler tube is also basically imported, such as Ф16mm×2.11-2.50mm, the annual demand for the length of 22-24m is 7,000 tons, the Ф16mm×1.2-3.0mm, and the annual requirement for the length is 12.5-18.0m. It is also 7,000 tons.
In January-November 2011, the state of power generation in China was as follows: The power generation capacity of power plants above designated size nationwide was 312,290 million kwh, which was an increase of 6.8% over the same period of last year.

The total power generation capacity of the major national power grids was adjusted to 2.719923 trillion kwh, and the maximum power generation load was 479.81 million kilowatts, an increase of 8.77% and 8.24% respectively from the same period of last year. From January to November, the capacity of power generation equipment for production of 6000 kilowatts and above was 7414.4200 kilowatts, an increase of 11.0% year-on-year. Among them, hydropower was 139.189 million kilowatts, an increase of 17.9% year-on-year; thermal power was 583.714 million kilowatts, an increase of 8.9% year-on-year; nuclear power was 8.846 million kilowatts, unchanged from last year.
Stainless steel pipe has a unique corrosion resistance, it can react with oxidants, forming a thin and dense oxide film, to prevent further oxidation reaction. For other types of metal pipes, there is almost no passivation function, which is one of the main reasons why the corrosion resistance of stainless steel pipe materials exceeds that of ordinary metal pipes. At the same time, stainless steel is also an environmentally friendly material. The stainless steel pipes do not cause secondary pollution to the water and meet the health requirements. Stainless steel pipe is a water pipe that can be completely recycled and will not leave unhandled garbage for children and grandchildren. The strength of the stainless steel pipe is higher than that of any water pipe material, which greatly reduces the phenomenon of the water pipe leaking due to external force and effectively saves water resources.
At present, China is already the world’s largest producer and consumer of building materials. The main building materials such as cement, flat glass, building sanitary ceramics, stone and wall materials have been ranked first in the world for many years. At the same time, the quality of building materials continues to increase, energy and raw material consumption decline year by year, new types of building materials continue to emerge, and building materials products continue to upgrade. In North China, there are many manufacturers of pipes, such as Hebei's Puri Steel. Among them, Mengcun, Hebei Province, is known as the “Capital of Chinese Pipe Fittingsâ€, which is the main gathering place for the production and sales of stainless steel pipe fittings in China. About 70% of the fittings in China are There is production in this place and it is also a Chinese export base for pipe fittings. Recently, the new project of Mengcun County: International Hardware Pipe Fittings City, covering an area of ​​600 acres, with first-rate facilities, including property, logistics, etc., is a modern pipe fittings city with epoch-making significance.
In the “Eleventh Five-Year Plan†period, investment in infrastructure construction has reached the middle plate, and the outbreak of investment in infrastructure construction such as roads and railways and the steady increase in ordinary civil construction investment have caused the construction industry to be on the upswing stage. At the same time, under the background of building an energy-saving society and the country’s ability to strengthen independent innovation, the theme of energy conservation and technological innovation will be a hot spot for the development of the industry.
Domestic stainless steel tube application of the most potential areas:
Vehicle / Automotive Industry: This is the fastest growing stainless steel tube application. Countries such as Sweden have made heavy use of stainless steel vehicles. Japan began to promote from the 80s, and currently its stainless steel train vehicles have reached 60%. The car industry is the focus of the development of stainless steel pipe applications. Baoxin stainless steel pipe exhaust pipe is mainly aimed at domestic and foreign high-end automotive market.
Water industry: Stainless steel pipe is the best material for water industry such as preparation, storage, transportation, purification, regeneration and seawater desalination. Construction industry: China will accelerate the process of urbanization, develop projects in the western region and state-guided residential construction, and all will drive the growth in stainless steel pipe demand. China began to use thin-walled stainless steel water pipes in 2000. Its industry standard was introduced in 2001, but it was not used on a large scale in the initial stage of promotion. However, in recent years, as people’s awareness of environmental protection has increased, thin-walled stainless steel pipes have become safe and reliable. The advantages of hygiene, environmental protection, and economical application have attracted more and more attention. Currently, there are professional manufacturers in Beijing, Guangdong and other places, and they are used in drinking water systems, hot water systems, and heating systems.
Environmental protection industry: Industrial waste gas, garbage and sewage treatment devices need to be made of stainless steel pipe. China's green sunrise industry will have a rapid development during the 10th Five-Year Plan period. In 2008, the total output value of China's environmental protection industry is expected to reach 200 billion yuan. During the 10th Five-Year Plan period, the average annual growth rate of China's environmental protection industry is 15%. . This will drive the demand for steel and provide numerous opportunities for steel companies and steel traders.
Industrial facilities: The proportion of stainless steel pipes used in industrial facilities in developed countries is generally 15%-20%, and the proportion of domestic applications is still very small. With the improvement of the quality of domestic stainless steel pipe products and the development of special brand products, the application of stainless steel pipes in domestic industrial facilities will increase year by year.
Home Appliance Industry: In the home appliance industry, the stainless steel tube has a large amount of usage, such as an automatic washing machine inner tube, a water heater liner, a microwave oven outer shell, a refrigerator lining, and ferritic stainless steel. The proportion of stainless steel tubes used in household electrical appliances in Western Europe is relatively large, and Asia is generally less used except Japan, which is close to European standards. China's microwave ovens, refrigerators, air conditioners, televisions and other home appliances industries are potential big markets for stainless steel pipe applications. It is estimated that in the next 5-10 years, it is expected that consumption of stainless steel pipes in the field of household appliances will increase from 8% to 10%, thus stimulating the consumption of stainless steel pipes. The demand for stainless steel pipes in the home appliance industry in China will reach 100,000 to 150,000 tons.
Third, the production capacity has increased and the production situation has improved: At present, the production capacity of stainless steel pipes in China can only meet the demand of 20%, so the production capacity needs to be greatly improved. Changes in the production situation are mainly manifested in two aspects. First, China's accession to the WTO will facilitate the import of stainless steel raw materials (including nickel, chromium and waste stainless steel). Second, the development of the Chinese stainless steel industry will certainly attract foreign investment.
Fourth, management improvement: After China's accession to the WTO, we must improve management and technology, which will help improve the competitiveness of China's stainless steel manufacturers.
