ASTM B462 Nickel Alloy UNS N10276 Blind Flange Hastelloy C276 BLRF Flange

Hastelloy C276 Flange , ASTM B462 UNS N10276 / 2.4819 Nickel Alloy Blind Flange

ASTM B462 C276 Hastelloy Blind Flange is a solid disk used to blank off the end of a piping system, a pressure vessel opening, or a valve. It is manufactured from a nickel-chromium-molybdenum alloy known for exceptional corrosion resistance in a wide range of severe environments.

Advantages of Using C276 Blind Flanges

1. Long Service Life: Drastically reduces maintenance and replacement frequency in aggressive environments.

2. Reliability and Safety: Provides a robust and leak-proof seal for isolating high-pressure, hazardous systems.

3. Versatility: A single, well-chosen material (C-276) can often handle multiple process streams, simplifying inventory.

4. High-Temperature Capability: Maintains strength and corrosion resistance at elevated temperatures.
