Advantages of IBR Reducing Flanges A reducing flange can simplify piping layouts where the connected pipe sizes differ. Its flanged connection allows equipment and piping sections to be assembled, inspected, maintained, and replaced more conveniently. Proper selection of material, pressure rating, dimensions, and temperature capability is essential for safe and reliable operation. For IBR applications, buyers should verify the applicable Indian Boiler Regulations, approved material specifications, dimensional requirements, and certification requirements before procurement.
