Introduction to GOST Flanges
GOST flanges are flange standards that follow the Russian State Standard (GOST). These flanges are widely used in various industries, especially in Russia and other countries that follow the GOST system. They are designed to ensure proper connection and sealing in piping systems, with specific dimensions, pressure ratings, and material requirements. GOST flanges come in different types such as weld – neck flanges, slip – on flanges, blind flanges, etc., and are crucial for maintaining the integrity and safety of industrial pipelines.
