IBR Reducing Flanges are specialized pipe flanges designed to connect pipes or piping components having different nominal diameters. These flanges provide a practical solution for reducing pipe size while maintaining a secure, bolted connection in industrial piping systems. Where applicable, IBR requirements make them suitable for specified boiler and steam-related applications subject to the relevant regulations, material specifications, and approvals. IBR Reducing Flanges are manufactured in different sizes, pressure classes, materials, and configurations to meet specific piping requirements. They are commonly considered for boiler plants, steam pipelines, process industries, power plants, and industrial utility systems.
