Reducing / Expander Flange

About Reducing / Expander Flange

Reducing and Expander Flanges are specialized pipeline flanges designed to connect pipes of different diameters. A reducing flange decreases the pipe size, while an expander flange increases it. These flanges eliminate the need for separate reducers or expanders, saving space and installation time. Induskart offers forged reducing and expander flanges in Carbon Steel, Mild Steel, and Stainless Steel, manufactured to ANSI B16.5 standards, ensuring dimensional accuracy, strength, and leak-proof performance.
