ASTM A105 carbon steel ring type joint (RTJ) flanges are designed to provide a high-integrity seal for high-pressure and high-temperature applications. The distinctive feature of RTJ flanges is the ring-shaped groove that allows for the insertion of a metal ring gasket, which creates a tight seal when the flanges are bolted together. Made from ASTM A105 carbon steel, these flanges offer excellent strength and durability. They are commonly used in industries such as oil and gas, petrochemical, and power generation, where a reliable and leak-proof seal is essential. RTJ flanges are particularly useful in applications that require frequent disassembly and maintenance.
