What Is Inconel Flanges?

A flange offers a method to connect pipes, valves, and other equipment to a piping system either using screws or welding procedures. The Incoloy 825 Flanges are austenitic grade made of nickel, chromium, and molybdenum with other constituting alloys. These flange offer exceptional resistance to corrosive and reducing media. The flange have enhanced tolerance to chloride ion stress corrosion cracking. A DIN 2.4858 Forged Flange has outstanding surface porosity and is resistant to sensitization in temperatures up to 760 degrees C. These flange have excellent mechanical properties and can be easily heat-treated. A forged flange can be easily formed and fabricated. Our institution is amongst the top echelons of Inconel 825 Flanges manufacturers who follow all international and national standards while manufacturing the best products using the latest technological advancements.

Supplier Of Nickel 825 Slip On Flange in RF/ FF/ RTJ, Available in Class 150 To 2500 in Mumbai


The ASTM B564 UNS N08825 Slip on Flange is a ring that is slid on the pipe and welded on both sides to prevent leakage. These flange are preferred in the industry due to their lower cost. Alloy 825 Flanges Socket Weld Flange possesses equal strength compared to a slip on flange. The flange has a socket that allows it to secure to a pipe and welded using a single fillet weld. These flange are seen in low-pressure conditions.
