Carbon Steel F70 Flanges are robust flanges crafted for tough industrial settings where high pressure and temperature are the norms. Made from ASTM A694 F70 grade carbon steel, these flanges boast remarkable mechanical strength and toughness, making them perfect for critical piping systems. Uday Flanges, a reputable manufacturer and supplier based in Dubai, UAE, provides top-notch Carbon Steel F70 Flanges in various styles, including weld neck, blind, slip-on, and threaded, all adhering to international standards like ASME, ASTM, and ANSI. These flanges find their place in the oil & gas, petrochemical, power, and refinery industries, where performance and reliability are non-negotiable.
Carbon Steel F70 Flanges are crafted from ASTM A694 Grade F70, a high-yield carbon steel that primarily consists of carbon, manganese, phosphorus, sulfur, and silicon, featuring a minimum yield strength of 485 MPa and a tensile strength of 655 MPa. This material is celebrated for its excellent impact resistance and toughness, making it particularly suitable for high-pressure pipeline systems. F70 flanges are often normalized or quenched and tempered to boost their strength and ductility. They maintain their mechanical integrity even in harsh environments, making them ideal for transporting oil, gas, and other pressurized media under extreme conditions.
