High pressure flange and pneumatic valve is how to connect

high pressure pneumatic valve flange steel gate is suitable for the nominal pressure PN. ~。 Mpa, working temperature - ℃ ~ ℃ under various working conditions such as petroleum, chemical industry, power plant of pipeline, cut off or connect medium. High pressure pneumatic valve flange connection steel gate applicable medium: water, oil, steam, etc. Operation mode: manual, gear drive, electric, etc.
my county flange industry for decades of time, during this period, domestic policy and the economy, for the flange industry provides favorable development condition, the rise of space is very large. Flange industry is expected in the next few years' time there will be a big improvement.
at present, China's petrochemical industry is moving toward large-scale, large-scale and internationalization direction development, will continue to maintain sustainable development in the future years. Domestic dozens of sets of thousands of equipment of oil refining and megaton ethylene plant will be new and renovated, flange for petrochemical opened up a broad market demand. In addition, the current domestic each refinery operating various types of pumps has been aging, need to update and reform.
in the coming year sinopec with flange is the development direction of large-scale, electromechanical integration, and product integration and standardization. Especially in high temperature and high pressure flange, flange at low temperature and ultra-low temperature, corrosion resistant stainless steel flanges flanges, conveying viscous medium and solid granules medium stainless steel flange production technology will be rapid development, the demand will increase significantly.
the apparent consumption of our country has reached the highest level close to world/total global consumption, per capita consumption of stainless steel. KG, leaps to the developing countries. Stainless steel flange has corrosion resistance, high strength, light, long life and other excellent characteristics. In recent years, stainless steel flange in shipbuilding, is widely used in the orbital vehicles, such as transportation, with the development of mechanical manufacturing, stainless steel flange will have more broad application prospects. But consumption growth is slowing, and by spending more than an average annual growth rate % of ultra-high speed development stage, to the growth of. % of the steady development stage.
flange market price is quite stable, although a slight lift each year, but are small and promising market prospect was well worth it. According to the National Bureau of Statistics in the statistics data show that China flange manufacturing enterprises above designated size has several, produce flange is close to ten thousand tons, gross industrial output value one hundred million yuan, profit. One hundred million yuan. In the future, the flange industry will develop towards two principal direction, one is from single varieties to more varieties and specifications, development of the second is to develop in the direction of energy saving. To meet the need of complete sets of manufacturing project, for an enterprise to manufacture the flange, it is decided to a flange manufacturer all provide trend will more and more.
