At our Canberra facility, we take pride in crafting and supplying top-notch carbon steel RTJ flanges, specifically designed for high-pressure industrial piping systems that demand dependable, metal-to-metal sealing. Our selection features both forged and machined RTJ flanges made from high-quality carbon steel grades (like ASTM A105/A105N and A350 LF2) and adheres to key international standards (including ASME B16.5, ASME B16.47, DIN, and EN). Our manufacturing process focuses on precision machining of the ring-groove face, strict material traceability, and comprehensive certification, guaranteeing leak-tight performance even in the toughest service conditions.
Carbon Steel RTJ (Ring-Type Joint) flanges consist mainly of carbon steel with minute proportions of manganese, silicon, sulfur, and phosphorus Their mechanical properties are high tensile strength (up to 530 MPa), good yield strength (approximately 250 MPa), and good ductility They are more resistant to shock and fatigue and thus are stronger at high pressures. Benefits of carbon steel RTJ flanges are low price, availability, and high pressure and high temperature resistance properties, rendering them suitable for oil, gas, petrochemical and other applications.

Our carbon steel RTJ flanges are crafted from premium forged carbon steel, offering outstanding tensile strength, yield strength, and stability under high pressure and temperature. The RTJ groove is meticulously machined to ensure the metal ring gasket seats perfectly, allowing for safe and consistent sealing in critical applications. Through rigorous inspection and testing, we make sure that the mechanical and dimensional properties meet or surpass client specifications and industry standards.
Carbon steel RTJ (ring type joint) flanges are mostly employed at high pressures and temperatures because of their tight sealing qualities They are most suitable for use in the oil and gas industry, petrochemical plants, power generation and chemical a is used in an RTJ system that places a metal ring on the flange face for a robust leakproof seal, hence making these flanges fit to withstand harsh conditions, such as extreme pressures and temperatures hard included Carbon steel RTJ flanges are very resistant, mostly in pipelines, applied in reactors, and other key systems.
