At present, domestic ammonia plant required the main valve, the cut-off valve, check valve, trap, butterfly valve, ball valve, Valves, valve, needle-valve, safety valve, high-temperature low-temperature valves. The cut-off valve by valve devices accounted for 53.4 percent of the total data, accounting for 25.1 percent valve, trap accounts for 7.7 percent, accounting for 2.4 percent safety valve, the valve and the valve from the low temperature and other accounting for 11.4%. E, ethylene plant, ethylene Device is the leading petrochemical plant, which required a wide range of valves.
Valve, the cut-off valve, check valve, ball valve leveraged take-off and landing in the majority, which takes the top gate. "Tenth Five-Year" plan, the country needs to build an annual output of 660,000 tons of ethylene 6 sets of equipment, the considerable demand for valves. In addition, large-scale ethylene and high-pressure polyethylene device needs to use ultra-high temperature, the more low-temperature and high pressure valve product line. f, air separation plant. "Air separation" that is, air separation, the device required cut-off of the main valve, safety valve, check valve, valve, ball valve, butterfly valve, low temperature valves. g, polypropylene unit, polypropylene is easy for the Propylene raw materials, polymer derived from high-molecular compound, which required the main valve device, the cut-off valve, check valve, needle-valve, ball valve, trap.
(7) power station with valve: the Power of China's large-scale construction of a positive direction, it required large-diameter high-pressure and the safety valve, relief valve, globe valve, gate valve, butterfly valves, emergency shut-off valve and flow control valves , Spherical valve sealing instruments, (according to the national "Tenth Five-Year Plan", with the exception of Inner Mongolia and Guizhou provinces can be built more than 200,000 kilowatt generating units, the only other provinces and cities to build more than 300,000 kilowatt generating units).
(8) with metallurgical valve: metallurgical industry required major acts of wear-resistant alumina slurry valve (in-flow valve) to regulate the trap. The main steel-making industry required sealed metal ball valve, butterfly valve and ball valve oxidation, as flash and reversing valve.
(9) combined Marine-valve: With the exploitation of offshore oil field development, and its ocean-valve made of the required amount gradually increased. Ocean off the platform needed ball, a non-return valve, multi-way valve.
(10) Food and Drug use valve: the industry's main stainless steel ball valve required, non-toxic plastic ball and butterfly valves.
3, foreign markets. With access to wto, China valve market is facing foreign competitors valve, the valve of imports from abroad will have a greater amount of growth, at the same time, the Chinese, low-grade products, valves, there will be much more room .
(1) China's purchase of valves from developed countries to developing countries: China from the developed countries need to buy the valves, api for the main valve, the cut-off valve, check valve, ball valve, butterfly valve, and so on.
(2) in the Middle East, Iraq and other countries, oil fields, pipelines from the destruction of China's imported oil pipeline systems and valves used: the Middle East, Iraq and other countries need to import oil from our system, with the main valve for the valve, the cut-off valve, check valve, The main long-distance pipelines and valves for flat-panel ball.
(3) the conventional import and export companies in general need to buy the common valve: common type of valve from the valve, the cut-off valve, check valve, ball valve, butterfly valve majority.
At present, domestic and international valve market is very intense competition, particularly in the domestic market, state-owned enterprises and township enterprises and private individual competition, combined with the relative purchasing power weakened, some of the valves so that enterprises are facing a crisis of survival, at the same time, foreign Some of the market opportunities and lead to domestic enterprises in order to survive efforts to open up. By the United States in the Middle East Iraq, Iran sanctions and export opportunities for the good of the situation, China's high quality, cheaper products, valves, it is easy to break into the market in the Middle East, exports to developed countries. As a result, all of the valves business, should seize the opportunity for domestic and international valve market demand and expand markets, increase exports in order to develop.
Third, the domestic development of the valve should be new products
Valve product development should focus on building the country's economic development to focus on. China's "Tenth Five-Year" will focus on economic construction, energy, agriculture, industry and environmental protection, urban construction, that is, valve products in the future the main market in electricity, petrochemicals, fertilizers, environmental protection and urban construction and other industries. These industries are yet to be developed or trial, but also improve the quality of the products of the main valves are:
