Gost 12820-80 Flange Dimensions

Russian-made Gost flange is a type of flange. The term "GOST" refers to a group of technical standards that have been upheld by the Commonwealth of Independent States (CIS) and the Euro-Asian Council for Standardization, Metrology and Certification (EASC), two regional standards organisations (CIS). The GOST contains a variety of regulated standards, with examples ranging from recipes and the nutritional information of brands popular in the Soviet era to charting guidelines for design documentation, such the GOST 12821-80 Threaded Flanges.

In the nations under the control of standards, the GOST concept is significant and well-known. The GOST 12821-80 Stainless Steel Flanges comprise Steel Butt-Welded Flanges, Blind Flanges (GOST12836-67), Plate Flanges, Welding Neck Flanges, and more. These GOST 12821-80 Carbon Steel Flanges are available in sizes DN15 to DN1600. The Gost 12820-80 Flange is not only offered in these sizes but also in a variety of styles or shapes, including plate flange, blind flange, welding neck flange, slide on welding plate flange, and steel butt-welded flanges.

Depending on the application, these Flange Gost 12820 forms or types are employed. The GOST 12821-80 RTJ Flanges are typically used in sectors including electric power, natural gas, shipbuilding, offshore oil and gas, and pipeline projects. Carbon steel (for example, A105, SS400, SF440 RST37.2, S235JRG2, P250GH, C22.8), stainless steel (for example, F304, F304L, F316, F316L, 316Ti), alloys like copper, nickel, titanium, brass, Hastelloy, Monel, etc. are among the materials used to make Gost 12821 Flanges. It's vital to remember that the GOST Blind Flange's characteristics, such as its strength or resistance to corrosion, depend on the material and surface treatment that are used to create the Gost 12815 Flanges.

Gost Standard Flange 12820-80 are most frequently available in screwed, forged, threaded, or plate forms. These Gost 33259 Flange shapes are often readily accessible in the market. For example, the standard for Plate Flanges is GOST12820-80, the standard for Blind Flanges is GOST12836-67, the standard for Welding Neck Flanges is GOST12821-80, and the standard for Steel Butt-Welded Flanges is GOST12821-80.

The Gost 12815 Flange has a nominal pressure range of PN6 Mpa, PN10 Mpa, PN16 Mpa, PN25 Mpa, PN40 Mpa, PN64 Mpa, PN100 Mpa, and PN160 Mpa. The packaging for Gost 12820-80 Flange Dimensions items is typically supplied in a wooden case, a wooden pallet, or a fumigated plywood.

The GOST 12821-80 Slip On Flanges' surfaces are treated by being painted with anti-rust paint or anti-rust oil. The GOST 12821-80 Blind Flanges may also receive a thin zinc film applied to their surface by plating them with transparent, yellow, or black zinc. Or by using the Gost 33259 Flange to Hot dipped Galvanizion technique to apply a thicker layer of zinc on it. According to client preference or the application for which the GOST 12820 80 Flanges will be used, surface coating is an option.
