Product description

GOST Russian standard flanges are a series of flanged connection systems for pipe and equipment connection developed under the GOST standard framework. Similar to the flanged connections of other standards (such as ANSI, JIS, etc.), GOST flanged connections also have similar components and functions.

GOST flanged connections typically include the following main components:

1. **Фланец (Flange) : ** GOST flanges are usually of a design similar to flat plates with a few holes in them for connecting bolts. The shape, number of holes and size of flanges are specified according to different GOST standards.

2. **Прокладка (Gasket) : * * placed a layer between flange gaskets, to ensure the sealing connection. These gaskets can be made of rubber, metal and other materials, depending on the standards and application requirements.

3. ** **Бол (Bolt) and Гайка (Nut) : ** bolts and nuts are used to connect flanges together to ensure the firmness and tightness of the connection through proper tightening force.

GOST flanged connections are widely used in the industrial field in Russia and some other countries. Similar to the flange connection standards in other countries, GOST flange connections are also available in different types, pressure grades and sizes to suit different application requirements.

In general, GOST Russian standard flange is a common flange connection system in Russia and some related regions, through standardized design and specifications, to ensure stable connection and fluid transmission under different working conditions.
