ASTM A182 F11 alloy steel ring type joint (RTJ) flanges are specialized components designed for high-pressure and high-temperature applications. Made from Grade F11 alloy steel, these flanges are used to provide a tight seal between two flanges, preventing leaks in critical piping systems. The RTJ flanges feature a ring groove designed to accommodate a ring joint gasket, which enhances the sealing effectiveness. These flanges are commonly employed in industries such as oil and gas, petrochemical, and power generation, where robust and reliable sealing solutions are essential. The flanges are precision-engineered to meet stringent standards, ensuring durability and performance in demanding environments.
