ASTM A182 Grade F5 alloy steel ring type joint (RTJ) flanges are specialized flanges designed for high-pressure and high-temperature applications. These flanges are made from ASTM A182 Grade F5 alloy steel, known for its superior strength and resistance to thermal degradation. The ring type joint flange design includes a raised ring on the flange face that forms a seal when compressed by a matching ring gasket. This design ensures a leak-proof connection in high-pressure systems. ASTM A182 Grade F5 alloy steel offers excellent mechanical properties, making these flanges suitable for demanding environments such as oil and gas, chemical processing, and power generation. They conform to ANSI/ASME B16.5 standards for dimensional accuracy and pressure ratings.
