Reducing flanges are a type of pipe flange that allows for a connection between pipes of different sizes. These flanges have a larger diameter on one side and a smaller diameter on the other, which enables them to join pipes with different diameters.
Reducing flanges are typically used in piping systems where the flow rate needs to be reduced or increased. For example, a reducing flange can be used to connect a large-diameter pipe to a smaller-diameter pipe, allowing for a reduction in flow rate. Similarly, a reducing flange can be used to connect a small-diameter pipe to a large-diameter pipe, allowing for an increase in flow rate.
Reducing flanges are available in various materials, such as stainless steel, carbon steel, and alloy steel, and they can be customized to meet specific requirements. They are typically used in industries such as oil and gas, chemical, and petrochemical, where the need for different pipe sizes is common.
