Carbon Steel Flanges are essential piping components used to connect pipes, valves, pumps, and other equipment in high-pressure and high-temperature industrial systems. These flanges offer excellent strength, durability, and leak-proof performance.
Manufactured from high-quality carbon steel, these flanges are widely used in oil & gas, refineries, power plants, petrochemical, and process industries where reliability and long service life are critical.
Carbon Steel Flanges are manufactured in accordance with ASTM and ASME standards. Commonly supplied grades include ASTM A105, ASTM A350 LF2, ASTM A350 LF3, and ASTM A516 Grade 60 / 70, offering excellent mechanical strength, pressure resistance, and toughness for low- and high-temperature applications.
