Product Description

GOST 12820-80 DN15 to DN1600 Plate Flange

 

Gost flange is a flange system from Russia, include Plate Flanges(GOST12820-80),Blind Flanges(GOST12836-67),Welding neck Flanges(GOST12821-80), Steel Butt-Welded Flanges GOST12821-80 etc., size from DN15 to DN1600.
 

These forms or types of Flange Gost 12820 are used depending on their requirement. Generally, the GOST 12821-80 RTJ Flanges find uses in industries like Natural Gas, Pipe Projects, Oil Field, Offshore, Water System, Shipbuilding, Electric Power, etc.The materials used to manufacture Gost 12821 Flanges include Carbon steel (for e.g. - A105, SS400, SF440 RST37.2, S235JRG2, P250GH, C22.8), Stainless Steel (for e.g. - F304, F304L, F316, F316L, 316Ti ), alloys like copper, nickel, titanium, brass, Hastelloy, Monel etc. An important point to note is that the properties of the GOST Blind Flange like corrosion resistance or strength will depend on the material and surface treatment selected to produce the  Gost 12815 Flanges.

Most common types of Gost Standard Flange 12820-80 include Screwed, Forged, Threaded or Plate. Usually, these forms of the Gost 33259 Flange are easily available in the market.The standard for the various forms of flanges are different for instance, the standard for  Plate Flanges is GOST12820-80, Blind Flanges is GOST12836-67,  Welding neck Flanges is GOST12821-80 and for Steel Butt-Welded Flanges, the corresponding standard number is GOST12821-80.

The nominal Pressure for the Gost 12815 Flange ranges from PN6Mpa, PN10Mpa, PN16Mpa, PN25Mpa, PN40Mpa, PN64Mpa, PN100Mpa, up to PN160 Mpa.Packing of the Gost 12820-80 Flange Dimensions products are generally supplied in a No Fumigate or Fumigate Plywood or a Wooden Pallet or a wooden Case.

Surface Treatment given to the GOST 12821-80 Slip On Flanges include being coated with either Anti-rust Oil or Anti-rust Paint. Another form of surface treatment done on the GOST 12821-80 Blind Flanges includes being either coated with a thin film of zinc by plating it via Transparent, Yellow or Black Zinc. Or by coating it with a thicker layer of zinc by  treating the Gost 33259 Flange to  Hot dipped Galvanizion process. Surface coating is available based on the customers requirement or based on the application  in which the GOST 12820 80 Flanges  will be used.
