Yousef Steel is a reliable manufacturer and supplier of Carbon Steel A182 Flanges based in Riyadh, Saudi Arabia. We pride ourselves on offering top-notch flanges that are built to endure high pressure, extreme temperatures, and harsh environments. ASTM A182 flanges are forged carbon steel components that play a crucial role in connecting pipes, valves, pumps, and other equipment within piping systems. Renowned for their strength, durability, and impressive resistance to mechanical stress, these flanges come in various types, including weld neck, slip-on, blind, socket weld, and threaded. At Yousef Steel, we prioritize compliance with international standards, ensuring our A182 flanges meet the stringent requirements of the oil, gas, chemical, and power industries.
Carbon Steel A182 Flanges are crafted from forged carbon steel, featuring a maximum carbon content of 0.35%, along with 0.60–1.05% manganese, and trace amounts of silicon, sulfur, and phosphorus. They boast a minimum tensile strength of 485 MPa and a yield strength of 250 MPa, along with commendable elongation and toughness. These flanges undergo heat treatment to enhance their mechanical properties, providing resistance to stress, fatigue, and pressure fluctuations. Their outstanding weldability and machinability make them ideal for high-pressure and high-temperature applications, while the forging process ensures a superior grain structure and durability compared to cast flanges.
