Introduction to GOST Flanges
GOST flanges are flange standards that follow the GOST (Gosudarstvennyy Standart, or State Standard) system, which is a set of standards used in the Soviet Union and some of the post – Soviet states. These flanges are designed to meet specific requirements in terms of dimensions, pressure ratings, and material properties. They are widely used in various industries, including oil and gas, chemical, and power generation, for connecting pipes, valves, and other equipment. The GOST standards ensure compatibility and safety in the piping systems, with specific marked pressure levels (such as PN numbers) and clear dimensional specifications. GOST Flanges
