China's large number of valve enterprises, highly competitive, the current status of the valve industry in what? "15" period will be how to develop? This reporter interviewed China General Machinery Valve Industry Association, asked them to talk about the future development of the valve industry. Reporter: It is said that more domestic valve manufacturers, but low profits, do you think is the reason of low productivity, or the problem of industrial structure? A: There are many enterprises engaged in valve production in our country, and most of them are small and medium enterprises. Only Wenzhou in Zhejiang Province, Henan Yang and other regions have hundreds of towns and private enterprises. However, there are only 488 enterprises in the country with annual sales revenue over 5 million, while only 176 belong to our valve association. Among them 152 valve manufacturers. It is estimated that China's annual output of industrial valves more than 100 million tons, of which about 2.01 million tons of high pressure valves: industrial output value 9.37 billion yuan, sales revenue 9.37 billion yuan, a profit of 310 million yuan. Therefore, the valve industry profits in our country is Very low, about 5% to 10%. However, after decades of struggle, we have been manufacturing hand-made from the early days of liberation and following the Soviet Union's standard production. Today, we have adopted automatic production lines, machining centers, automated and semi-automated operations, produced in accordance with European and American standards, and established our own National standard. At present, we can produce complete sets of valve equipment for large-scale projects such as refining, nitrogen fertilizer and long-distance pipeline transportation such as 400,000 tons of synthetic ammonia, 520,000 tons of urea, 60,000 tons of high-pressure polyethylene, 50,000 tons of ethylene, 1.2 million tons of oxidation Aluminum, 500 ~ 10 million tons of oil refining, 600,000 kilowatts generating sets, West-East gas transmission and other projects. Now, the scale and layout of the valve industry in our country is becoming more and more reasonable. Provinces and cities have their own valve manufacturers. The number of flash enterprises, their size, the number of workers and the number of their technicians have been greatly improved: their output, output value and economic benefits have been continuously raised; technologies The level of continuous improvement, product variety greatly increased, the early days of the founding, the valve plant can only produce a small amount of a variety of low-pressure valve specifications, has been able to produce a full range of gate valves, globe valves, check valves, diaphragm valves, safety valves, valves Steam traps and emergency shut-off valves and other 12 categories, more than 3000 models, more than 40,000 specifications of the valve products, the valve pressure from 2X10 -8 bar ~ 1460bar, the temperature from -270 ℃ to 1200 ℃ low temperature to 3430 ℃ High temperature, the nominal diameter from 1mm ~ 9750mm, widely used in people's lives, industrial and agricultural production, offshore oil, oil and gas, transportation, urban construction, aerospace technology and nuclear industry; product quality continues to improve, longer and longer life, valve repair The period has been extended from the past few weeks to more than 1 year and a half, the qualified product rate of more than 90%, the valve long-term existence Of the "one running two leaks" phenomenon has been significantly improved, 91 enterprises received ISO9000 quality certification; process equipment level continuous improvement, both machining and thermal processing technology have been imported foreign advanced technology. Some township and village enterprises have also come to the fore, not only the rapid development of scale, product variety and quality even exceed the state-owned enterprises. However, China's valve product variety can only meet 80% of national needs, output can only meet 90%, and the middle and low product surplus, lack of high-quality valves. The biggest problem is that some small businesses have neither drawings nor technology, nor technical people, the products do not meet the national standards, and even the production of counterfeit and shoddy products has seriously disrupted the valve market and has also wrecked valuable resources. Many big state-owned enterprises are faced with the problems of heavy burden, financial difficulties and outdated technologies. They also have no power to carry out technological transformation and investment in new projects, and the economic benefits are naturally not good. Therefore, the valve products can not fully meet the market demand, some foreign manufacturers by * its excellent product quality and effective marketing tools, occupy a considerable part of the market share. Reporter: We have noticed that many effective valve enterprises have introduced foreign technologies or taken joint ventures with foreign companies to produce co-products. Are advanced foreign technologies decisive? A: China's valve technology and the international advanced level about a difference of about 10 years, such as some high temperature and pressure and corrosion-resistant products can not be produced, the offshore oil exploitation of the valve requires 10 to 15 years without leakage, we do not reach this Claim. Long-distance pipelines are also using the main line of foreign products, domestic products can only be used in the feeder. Not only in technology, there is not a small gap in management. We lack the high level of large-scale valve business executives, especially those who know the capital operation of the valve business experts, is not conducive to the survival of the fittest SMEs bankruptcy, mergers and acquisitions, restructuring, the formation of our own big business, with famous foreign companies competition. We have a lot of enterprises that have imported advanced technology from foreign countries to undertake joint ventures or cooperative projects. They use most of the technologies of Japan and the United States, and other countries. For example, Dalian High-pressure Valve Factory introduced the proprietary technology of steam trap of Velan Engineering Company in Canada and Tianjin Tanggu Valve Factory introduced Mark Control Intrrnational Co., Ltd.'s manufacturing technology of mid-line wafer clamp butterfly valve: Tianjin Valve The introduction of the United States Mark International Control Company of high pressure die-casting steel valve manufacturing technology; Shanghai Valve Factory introduced the German Babukeke high-pressure safety valve Technology: Lanzhou High Pressure Valve Factory introduced the United States inventory analysis (Cooper) valve company of high quality stainless steel and Special alloy steel valve; Shenyang high school pressure valve plant introduced the United States ACF-WKM company's pipeline valve proprietary technology; Shanghai valve Wuchang introduced the British Sandas Valve Co., Ltd. diaphragm valve actuator and diaphragm valve proprietary technology; Beijing valve The plant introduced the proprietary technology of the German company Gestra BK15 steam traps; Shanghai Lianggong Valve Factory introduced the proprietary technologies of pneumatic and electric drive mechanisms for Biffi valves in Italy. China's valve technology has played a catalytic role to improve and enhance the product's Times and quality, not only to meet domestic market demand, many products are also exported to other countries.
