Application prospects of copper pipes

Relevant experts pointed out that according to the development trend of China's air conditioners and other related industries, China's copper pipe market has hidden business opportunities despite the changes. The next 10 years will be an important period for the development of China's copper pipe industry. In addition, the combination, reorganization and restructuring among enterprises will become the trend of industry development, and entering overseas markets will become an inevitable choice for enterprise development. China's copper tube industry has achieved a qualitative leap. According to expert analysis, copper tube is one of the fastest growing products in the production of copper processing materials in China. In 2002, China's copper tube production was close to 1/5 of the world's total copper tube production. In 2002, China's air-conditioning production was estimated at 27 million units, and the use of ordinary internal thread copper pipes alone reached 54,000 tons.
Therefore, if China's output of air conditioners reaches 30.5 million units in 2005, the consumption of ordinary internal thread copper pipes will be close to 92,000 tons. Therefore, industry experts believe that the next 10 years will be an important period for the development of China's copper tube industry. The output of China's copper tube will increase at an average rate of 5% per year, and before 2005, this growth rate could even reach 8%. %. According to the introduction of the Copper Pipe Examination Department of the China Industrial Product Production License Office, there are currently 260 companies that have submitted applications for the issuance of copper pipe production licenses. Based on this calculation, there should be about 300 copper pipe manufacturers in China. According to the latest data analysis of CRU, China has become the second largest copper tube producer and consumer country in the world after the United States. Compared with the previous year, the growth rate was as high as 15% and 10% respectively. If calculated at an average annual growth rate of 8%, the total consumption of copper pipes in China will reach 560,000 tons and 820,000 tons in 2005 and 2010, respectively, indicating that China's copper pipe market is extremely broad. After a series of technological transformation and scale expansion in the past 10 years, the production of copper coils in China has undergone earth-shaking changes, and the output and quality have made a historic leap, basically reaching the world's advanced level. According to incomplete statistics, by the end of 2002, China's copper coil production capacity was about 300,000 tons, ranking first in the world; the current actual production of copper coils is about 120,000 tons, of which internal thread coils are about 60,000 tons. Not only can it meet the needs of the Chinese market, but also some are exported to overseas. Strong demand for high-efficiency heat-dissipating copper pipes In recent years, in addition to the decline in copper pipe production in Western countries, and the crackdown on smuggling, China's air conditioner manufacturing industry has grown rapidly, creating an excellent opportunity for China's copper coil production. opportunity.
In 1998, the total output of air conditioners in China exceeded 10 million units, exceeded 26 million units in 2001, and exceeded 30 million units in 2002. Currently, China's production capacity is about 40 million units. In order to adapt to the development of the air-conditioning industry, by the end of 2000, the production capacity of copper coils and air-conditioning tubes in China had increased to 280,000 tons, an increase of about 4 times compared with 1990. Due to the stable performance, good uniformity, high blanking aging and high yield of copper coils, most air conditioner manufacturers use copper coils with a coil weight of 100 to 200 kg. In order to further improve the thermal efficiency and energy saving level, and manufacture high-efficiency, energy-saving and environmentally friendly air conditioners, it is necessary to use internal threaded copper coils. In addition, because the inner thread makes the medium form turbulent flow and speed up its flow rate, the thermal conductivity is greatly enhanced compared with the smooth pipe of the same specification, the thermal efficiency is increased by 20%-30%, and the energy can be saved by 15%. By the end of 2002, the usage of internally threaded copper pipes by air conditioner manufacturers had reached 50% of the total usage of copper coils, and it was estimated to exceed 60% in 2003 (the usage of threaded pipes by major air conditioner manufacturers in 2003 could reach 50%). 70%), and will be as high as 80% by 2005. That is to say, in 2001, 2002 and 2005, the total demand for copper coils for air conditioners was 60,000 tons, 80,000 tons and 150,000 tons respectively, of which the total demand for internally threaded copper coils would reach 30,000 tons, 50,000 tons and 120,000 tons. Entering overseas markets has become a choice for enterprise development. At present, from the perspective of market supply and demand, the supply of copper coils in China has exceeded the demand. 2002 was the most competitive year in the history of China's copper tube coil market. On the one hand, the continuous development of China's air-conditioning industry has driven the continuous growth of copper tube consumption in China, providing huge market space and development opportunities for copper coil tubes; on the other hand, with the continuous progress of air-conditioning manufacturing technology, copper tube The quality and technical requirements are getting higher and higher, and the market pattern of oversupply promotes the competition in the copper tube market to escalate day by day, forcing all production enterprises to continuously improve the level of technical equipment, find a way out in terms of industrial scale and product quality, and the market has become the configuration of China. The main body of copper tube production factors. Experts predict that in the next 10 years, while the output is growing rapidly, the varieties, production technology and equipment of China's copper pipes will also undergo corresponding changes. Among them, air-conditioning cooling radiator pipes will gradually realize all internal threads, and develop in the direction of small diameter, complex tooth shape, high heat dissipation and high cleanliness. At the same time, the production and application of welded high-efficiency radiator pipes and external finned pipes will also achieve Breakthrough progress. At the same time, the technology and equipment level of China's copper tube production will also be comprehensively improved, that is, the horizontal casting-planetary rolling-disk pulling and upper-drawing cold processing methods will attract more attention from enterprises.
