GOST Flange

A GOST flange is a Russian standard that adapts to different European, Asian, and other national standards. The GOST Flange is used to create a crucial channel to transport fluids and gases across different industries. These flanges are used to securely seal the flange and dismantle it when required. They are easy to clean and have a long service life. GOST Standard Flanges can connect pipes, valves, tubes, and other equipment to efficiently connect it to a pipeline. These flanges are designed in standard sizes of 15 NB to 200 NB. They are available in pressure classes of 150 to 2500 LBS. A Gost 33259 flange can be threaded, forged, screwed, or plate formed. They are available in 6Bar, 10Bar, 16Bar, 25Bar, and 40Bar. They can be customized to meet several requirements of our esteemed customers.

The GOST 12815 Slip on Flange is a ring that is placed at the end of a pipe as it is slid and welded using one or more fillet welds. They are well-suited in the oil and gas industry as they are available at economic prices compared to other flanges. These flanges are recommended for low-pressure and temperature conditions. A GOST 12821-80 Blind Flange is designed without a bore at the center. The primary use of the flange is to act as blanks to terminate the flow of media in the system. These flanges are usually bolted, allowing them to be used in repair and maintenance projects. The GOST 12815-80 Orifice flange is used with meters to measure the rate of flow of liquid or gaseous media. The flanges are available in raised, flat, and ring-type face.
