Din steel flange
DIN steel Flange is a very popular in the world a kind of flange, become the German standard flange. Before the flange standard for DIN2501, 2633, 2634 and so on, now universal flange standard is DIN EN 1092.Our company has 36 years of production of flange, in China enjoy a high reputation, is PetroChina, Sinopec’s member units. Export Flange 15, in the international also participated in many large-scale projects. has passed the ISO and CE certification, products in line with international standards, advanced technology and reasonable price, is a lot of engineering and inventory business customers the best partner.

The differences between ASME flange and DIN flange
American Standard Flange (ANSI) Pressure Rating: Class 150 300 400 600 900 1500 2500 Total 7
Corresponding pressure levels PN 2.0, 5.0, 6.8, 10.0, 15.0, 25.0, 42.0 MPa
European-standard Flange (DIN) Pressure rating: PN 0.1 0.25 0.6 1.0 1.6 2.5 4.0 6.3 10.0 16.0 25.0 MPA Total 12
European-standard system and the United States standards system, whether flange or pipe, can not be mixed use. American national standard ANSI B16.5 steel pipe FLANGE and flange pipe fittings, is a more mature, more complete, more popular international advanced standards.
ANSI B16.5 with other related ANSI, ASTM, API, MSS pressure Piping Application standard system formed on the basis of a large number of research experiments, has decades of practice testing, is a relatively advanced, scientific standards, widely accepted by other countries in the world.
The characteristics and service life of the DIN flange summer testing are related to these factors
In the summer when the flange in the installation and use, the flange is often to detect the tightness, in the industrial field, the role of the flange is very obvious, often used in sealed containers, the container flange is also known as equipment flange, is generally the equipment body parts associated with the flange, pressure vessel flange is a device in the flange of the pressure properties of a type.
Often many of the container leakage is connected with the flange, because the flange joint seal failure Light causes energy, raw material waste, heavy will lead to equipment scrap, shutdown, casualties and serious environmental pollution. Flange in use usually have matching gasket, gasket is a kind of plastic deformation, and has a certain strength of the material made of the ring, most of the gaskets are from non-metallic plates, or by professional factory according to the specified size, the material for asbestos rubber plate, asbestos plate, PTFE plate, polyethylene board, etc. Also useful thin metal plate (tin, stainless steel) asbestos and other non-metallic materials wrapped up in the metal package gasket, there is a thin steel belt and asbestos belt around the wound-type gasket, the most commonly used is stainless steel belt and graphite wound metal wound gasket, depending on the use of the environment, winding belt can also use asbestos, ordinary rubber gasket for temperature less than 120 ℃ occasions, asbestos rubber gasket for water vapor temperature less than 450 Dingxiang flange ℃, oil temperature is less than 350 ℃, pressure less than 5MPa occasions, for the general corrosive medium, the most commonly used is acid-resistant asbestos plate.
High pressure vessel flange is used for the nominal pressure of 0.25-1.6mpa, the operating temperature is higher than the -20℃~300℃ steel pressure vessel, a flat welding flanges. Therefore, as the industrial field, the flange connection should be checked regularly, found that there is a bubble in the flange weld, the leakage of the flange for the surface with neck flat welded steel pipe flange, the material is 304 of its contact medium for gaseous vinyl chloride monomer (VCM) and water, the design pressure is 1.4MPa, the maximum working pressure is 1.1MPa, the reaction temperature is 64.7 ℃, the temperature range is 30~70℃.
