The high pressure flange is suitable for pipelines on the conditions that PN10.0～25.0Mpa, working temperature —29℃～600℃, such as the petroleum, chemic, thermal power station to cut off or associated with the medium. Underhand flange connecting steel gate valve is acceptable for media like water, oil and steam.The operating methods are: manual drive, gear drive, electric drive, etc..
Flange industry has developed for over a decade, in those times, outside domestic Chinese policies and financial situation provided a great condition to build up the flange industry. What’s more, the raised space which very huge. Flange industry is expected to have a more substantial upgrade in the next few years.
At the moment, China’s petrochemical industry is able to the direction of big-scale and international. Over the following five years, it continually maintain sustainable development. Dozens teams of ten millions-a great deal of oil refining unit and million-a great deal of ethylene plant is going to be built and expensed, which uncovers a perse niche for the Petrochemical valve and flange. Moreover, the various types of pumps running in domestic refineries have aged, which needs updating and remodeling.
Next five years, the growth direction of utilizing flange trends to large scale, mechanical and electrical integration, in addition to Standardization and handle set. Specifically in high temperature and high pressure flange, low temperature flange and cryogenic flange, stainless steel flange, conveying sticky medium and the production technology of solid granules medium stainless steel flange develop rapidly, the demand will greatly increase. The price of flange companies are relatively stable, but with a slight rise and fall yearly, the magnitude is incredibly small, hence the flange marketplace is still bright.
