Alloy steel reducing flanges are specialized components used to join pipes of different diameters within a piping system. These flanges have an integrated design that accommodates a gradual change in pipe diameter, enabling a smooth transition between different sizes. Made from high-strength alloy steels such as ASTM A182 F5, F9, or F11, these flanges are engineered to handle high-pressure and high-temperature environments. The reduction feature is often used in applications where a change in pipe size is necessary, without the need for additional fittings or transitions. Reducing flanges are manufactured to standards such as ANSI/ASME B16.5 and B16.47, ensuring compatibility with various piping systems. They are commonly used in industries such as petrochemical, power generation, and water treatment where robust and reliable connections are essential.
