GNEE ASTM B407 UNS N08811 Nickel Alloy Tube for Petrochemical
ASTM B407 UNS N08811 (Incoloy 800HT) nickel alloy seamless tubes are frequently used in the petrochemical industry due to their excellent high-temperature strength, oxidation resistance, and corrosion resistance, especially in demanding environments involving heat exchangers, piping systems, and other high-temperature applications.
Key Features of ASTM B407 UNS N08811 Seamless Pipe
High-Temperature Resistance
N08811 alloy seamless pipe exhibits excellent thermal stability, making it well-suited for long-term exposure to high temperatures up to 1100°F (593°C) and above.
Corrosion Resistance
N08811 alloy seamless pipe exhibits excellent resistance to oxidation, carburization, and sulfidation, even in extreme environments such as chemical processing plants.
Mechanical Strength
N08811 alloy seamless pipe features enhanced mechanical properties due to the addition of appropriate amounts of titanium (Ti) and aluminum (Al), ensuring excellent creep and stress-rupture strength.
Seamless Structural Properties
The seamless manufacturing process for N08811 alloy seamless pipe ensures uniformity, eliminates weak points, and offers greater strength and reliability than welded pipe.
