What is a Stainless Steel Expander Flange?

Stainless Steel Expander Flanges – Manufacturer & Supplier in India

A Stainless Steel Expander Flange is a unique type of flange designed to connect pipelines with different diameters by gradually increasing the pipe size. This helps in improving flow dynamics and reducing turbulence. Expander flanges serve as an alternative to reducers and weld neck flanges, making them ideal for high-pressure and high-temperature applications.
