Demand Forecast of General Valve in China Petrochemical Industry
With the "Tenth Five-Year" valve market and the development of the industry within the various changes in the valve shares and private enterprises increased, the valve production increased, a substantial increase in valve production. Valve market complete sets, complete sets of levels and complete sets of capacity have greatly improved. At present, the current situation for the valve market, the "Eleventh Five-Year" period of the petrochemical valve demand forecast as follows: "Eleventh Five-Year" period, the petrochemical ethylene cracking gas with high-temperature valve is 800000 tons ethylene plant cracker exports Pipeline essential valves, valve enterprises should be in response to this situation, consider the development of cracked gas valve. In addition, large-diameter high-pressure ball valve, large diameter pipeline valve, LNG cryogenic valves have greater demand. The entire general equipment and valve industry is expected during the "Eleventh Five-Year" period, the total demand of 345 million. In addition, according to the needs of the development of national economy in our country, the development of valves focuses on the development of new valves for supporting the construction of major projects such as thermal power, nuclear power, hydropower, large-scale petrochemicals, oil and natural gas gathering and transportation lines, coal liquefaction and metallurgy. In the development of these new products at the same time, should pay attention to the promotion and application of new technology, such as the development of high temperature and high pressure power station and nuclear power plant valve using forging welding vacuum electron beam welding new technology and shear extrusion technology; development of long-distance pipeline large diameter The overall ball valve application of the overall welding technology.
