Carbon steel ASTM A105 blind flanges are essential components in piping systems, primarily used to close the ends of pipes, valves, or equipment nozzles. Manufactured from ASTM A105 carbon steel, these flanges offer superior strength and durability, making them ideal for high-pressure and high-temperature applications. Blind flanges are round plates with bolt holes around the perimeter and are used to block off a section of pipe or vessel, ensuring a secure and leak-proof seal. Commonly found in industries such as oil and gas, petrochemical, and power generation, ASTM A105 blind flanges help facilitate maintenance and repairs by allowing easy access to the sealed-off sections of the system.
