Low Temperature Carbon Steel ASTM A350 LF2 spectacle blind flanges are crucial components used to isolate sections of piping systems in low-temperature environments. Constructed from ASTM A350 LF2 carbon steel, these flanges are designed to withstand temperatures as low as -50°F (-45°C) while maintaining high strength and toughness. The spectacle blind flange consists of two circular plates: one with a solid disc for blocking flow and the other with a central opening. This design allows for quick and easy isolation of a pipeline or equipment for maintenance or modification. Spectacle blind flanges are widely used in industries such as oil and gas, chemical processing, and power generation, where reliable and effective isolation is essential.
