High pressure valve technology into China's valve market bottlenecks

日期:2013/6/10
In our current valve on the market, in addition to low-pressure valve to achieve a level acceptable to the international market, the high pressure valves still need to rely on imports. Continued good macroeconomic situation, the valve industry, most of the production and sales targets are maintained rapid growth, but by the price war, industry sales revenue and profit over last year dropped significantly. With the world economic recovery, China's import and export of valve products also increased, but due to the high-end technology with foreign manufacturers are still a wide gap between the next period of time, product technology will be restricting our development of a valve products bottlenecks.
    
Valve oil, chemical industry, power stations, long-distance pipelines, shipbuilding, nuclear industry, a variety of cryogenic engineering, aerospace and marine oil and other economic sectors indispensable fluid control equipment. After years of development, China's valve business volume ranks first in the world, a variety of about 6,000 more than the size of the valve, which annual output of more than 5 million have 900.
    
From the product point of view, China's valve industry is now able to produce more than a dozen categories of products, such as gate valves, globe valves, ball valves, butterfly valves, safety valves, check valves, throttle valves, plug valves, valves, diaphragm valves, traps, emergency shut-off valve, the maximum temperature reached 570 ℃, the lowest -196 ℃, maximum pressure of 600MPa, the maximum diameter to 5350 mm. In addition, according to the relevant department statistics, China's annual valve market turnover of up to 500 billion yuan, of which over 100 billion market by foreign occupation of the valve business.
    
At present, China's valve industry, there are still some problems, such as valve company mainly low-level, small-scale, family-owned enterprises. On the product, due to repeated investment, technology transfer is not enough, our valve leading enterprise products is still low quality mass products. At present our production of various valves widespread leakage, internal leakage, the appearance is not high quality, short life, the operation is not flexible and valve actuators and pneumatic devices are not reliable shortcomings, some products are only equivalent to the early 1980s international level, a number of high temperature and pressure and the critical need for the valve device is still dependent on imports. In addition, China's valve industry in the industrial structure, the valve industry, industrial chains, and industry on both the degree of specialization with foreign enterprises there is a big gap.
  
Resulting in poor quality valve products domestic reasons: the rapid expansion of the market, the original state-owned enterprises have Guantingbingzhuan valve, although a number of township enterprises developed rapidly, but due to the low starting point of township enterprises, the technical force is very weak, poorly equipped, products Most are imitating production, especially for the low-pressure valves for drainage problem is serious.
    
But the problem does not affect the future of China's valve industry broad prospects. This is mainly due to the support of national policies and strong market demand valve products, especially the construction of several centuries 'West-East', 'West to East', 'South' and started the project requires a lot of valve products supporting . In addition, China is facing the era of industrialization, the petrochemical industry, power industry, metallurgical industry, chemical industry and urban construction will enhance the use of large valve on the valve products. For example, the power industry 'Eleventh Five-Year' during the coal units in large and medium-sized valves required forecast projects a total of: Valves total demand of 153,000 tons, with an annual demand of 30,600 tons; valves total demand amounted 3.96 billion yuan, average demand amounted to 792 million yuan. In addition, China is becoming the world's largest processing plants, manufacture of valve products face greater space for development.
     
Thus, as long as companies can seize opportunities, strengthen research and development capabilities, and continuously improving product technology content and quality of products, we can in the fierce competition in the market initiative.
