ASTM A182 F91 alloy steel reducing flanges are used to connect pipes of varying diameters in high-pressure and high-temperature environments. These flanges are designed with a reduction feature that allows for a smooth transition from a larger diameter pipe to a smaller one, thereby maintaining flow efficiency and reducing turbulence. Manufactured from F91 alloy steel, these flanges offer superior strength, thermal resistance, and durability, making them ideal for demanding applications such as power generation, petrochemical industries, and heavy industrial systems. They are available in various sizes and pressure ratings to meet specific system requirements.
