Description Of Incoloy 800 Nickel Alloy Tube
Incoloy 800 Nickel Alloy Tube is a high-performance tubular product manufactured from Incoloy 800 (UNS N08800), a nickel-iron-chromium alloy designed for high-temperature applications. Incoloy 800 was developed in the 1950s to provide a heat- and corrosion-resistant alloy with a relatively low nickel content, and has been widely used for its strength at high temperatures and its ability to resist oxidation, carburization, and other types of high-temperature corrosion.
The alloy offers excellent high-temperature strength and creep resistance, with good resistance to oxidation and scaling up to approximately 1100°C. It also resists carburization and does not form the embrittling sigma phase in the critical 1100–1600°F range. These properties make Incoloy 800 tubes particularly suitable for heat exchangers, furnace components, petrochemical cracking tubes, and power generation equipment.
Incoloy 800 nickel alloy tubes are available in custom outer diameters, wall thicknesses, and lengths, with surface finishes including annealed, pickled, and polished. The material complies with ASTM B163 / ASME SB163, the standard specification for seamless nickel and nickel alloy tubes for condenser and heat-exchanger service. Typical applications include heat exchangers, furnace components, petrochemical processing, and power generation.
Applications Of Incoloy 800 Nickel Alloy Tube
Heat Exchangers: Incoloy 800 tubes are widely used in shell-and-tube heat exchangers, condensers, and evaporators in chemical and petrochemical industries.
Furnace Components: Used in high-temperature furnaces, including steam-methane reformer tubes, pyrolysis furnace tubes, and heat treatment equipment.
Petrochemical Industry: Used in cracking tubes, pigtails, headers, and other high-temperature components in ethylene and petrochemical processing.
Power Generation: Used in boiler tubes, superheaters, and heat recovery steam generators (HRSG) in fossil-fired and nuclear power plants.
Chemical Processing: Used in equipment handling high-temperature gases, carburizing atmospheres, and corrosive chemicals.
Nuclear Industry: Used in nuclear reactor components and heat exchanger systems.
