    Development trend of domestic high - pressure valve industry

    The reason for the low quality of the valve products is that, due to the rapid expansion of the market, the original state-owned valve enterprises have shut down and transferred. Although a number of township enterprises have developed rapidly, due to the low starting point of township enterprises, the technical force is very weak, the equipment is poor, Are imitating the production, especially for the low-pressure valve with a serious problem of water supply and drainage, but the above issues do not affect the future of China's valve industry's broad prospects. This is mainly due to the support of national policies and the strong demand of the valve product market. In particular, the projects of "West-to-East Gas Transmission", "West-to-East Power Transmission" and "South-to-North Water Diversion Project" are required to complete a large number of valve products .

    In addition, China is facing the era of industrialization, the petrochemical industry, power industry, metallurgical industry, chemical industry and urban construction, such as the use of large valves will enhance the demand for valve products. For example, the power industry, "Eleventh Five-Year" period in the coal-fired units large and medium-sized projects required for the total valve projections: total valve demand of 153,000 tons, the average annual demand of 30,600 tons; valve total demand of 3.96 billion yuan, The average annual demand for 792 million yuan. In addition, China is gradually becoming the world's largest processing plant, valve products, processing and manufacturing face greater room for development can be seen, as long as companies can seize the opportunity to strengthen research and development capabilities, and continuously improve the technological content of products and product quality, can In the fierce competition in the market take the initiative.

    In China's current valve market, in addition to low-pressure valve to reach the international market can accept the level, the high-pressure valves still need to rely on imports. In the macroeconomic continued optimistic about the situation, the valve industry, most of the production and sales targets have maintained rapid growth, but by the price war, the industry sales revenue and profits fell sharply over the same period last year. As the world economy pick up, China's import and export of valve products also increased, but because of high-end technology with foreign manufacturers still have a large gap compared to the next period of time, product technology will become a constraint on the development of China's valve products bottleneck.

    From the product situation, China's valve industry has been able to produce more than a dozen categories of products, such as gate valve, globe valve, ball valve, butterfly valve, safety valve, check valve, throttle, plug valve, Traps, emergency shut-off valve, the maximum temperature reached 570 ℃, the lowest -196 ℃, the maximum pressure of 600MPa, the maximum diameter of 5350 mm. In addition, according to statistics from relevant departments, China's annual turnover of the valve market as high as 500 billion yuan, of which more than 100 billion market by foreign enterprises occupied the valve. Valve is the oil, chemicals, power plants, long-distance pipelines, shipbuilding, nuclear industry, a variety of low-temperature engineering, aerospace and marine oil production and other sectors of the national economy indispensable fluid control equipment. After years of development, the number of valve enterprises in China ranks first in the world, the size of the valve about 6,000 enterprises, of which more than 500 million annual output of 900.

    At present, China's valve industry still has some problems, such as China's valve business mainly to low-level, small-scale, family-based enterprises. In the product, due to repeated investment, the introduction of technology is not enough, China's leading enterprise valve products is still low-quality mass products. At present, China's production of a variety of common valve leakage, leakage, the appearance of the quality is not high, short life, the operation is not flexible and electrical devices such as valve and pneumatic devices unreliable shortcomings, some products only equivalent to the early 80s of last century Of the international level, a number of high temperature and pressure and the key devices on the valve is still dependent on imports.
