ASTM A182 Grade F11 alloy steel threaded/screwed flanges are used in various piping systems where a bolted connection is required. Made from F11 alloy steel, these flanges offer excellent strength and high-temperature resistance, making them suitable for demanding applications. The threaded design allows for easy installation and disassembly without welding, which is advantageous in situations where welding is impractical. The flanges are machined with internal threads that match the corresponding pipe threads, ensuring a secure and leak-proof connection. Commonly used in industries such as chemical processing, power generation, and oil and gas, these flanges provide reliable performance under high pressure and temperature conditions.
