GOST STANDARD FLANGE (GOST 12820/GOST 12821/GOST 33259) – MANUFACTURERS & STOCKISTS
GOST Standard Flanges abide by the standard called GOST. It is a Russian standard that adapts to the standards of European, Asian standards and many other national standards. Dinesh Industries is a producer of different flanges in different material grades that come with the GOST standard. The Gost Standard Flange Dimensions vary with specification and other standards. There are small to medium scale diameter flanges that operate in different applications. The Gost 12821 Flange is a stainless steel flange that can range between the DIN15 to DIN1600. There are different types of the flanges as well. The GOST 12821 80 flange is used in oil fields, offshore oil industries, natural gas industries and in water systems.
The electric power plants and shipbuilding industries use this standard of flanges as well. There are different types such as the weld neck, slip on, butt weld and blind flanges. The Ghost Blind Flange is used to terminate a pipe line either temporarily or permanently. The Ghost Weld Neck Flange is used to have more welding surface and strength over connection. The Ghost Plate Flange is used to add more connection surface to blunt pipe ends and the Ghost Slip On Flange is useful when connecting seamless pipes together. You can get any types of flanges from us and please feel free to contact us with your inquiry.
