Seamless Incoloy 800 Pipe/800 INCOLOY SEAMLESS pipe/N08810 seamless tube/1.4876 seamless pipe is a premium, high-performance product chosen for the most demanding applications where failure is not an option. Its combination of high-temperature strength, exceptional corrosion resistance, and the inherent reliability of a seamless construction makes it a critical material in the energy, chemical, and processing industries. When specifying, it is crucial to select the correct grade (800, 800H, or 800HT) based on the specific temperature and mechanical requirements of the application.

Advantages of Seamless Incoloy 800 Pipe

Superior Pressure Integrity: The absence of a weld seam eliminates a potential weak point, making it the preferred choice for high-pressure applications.
Excellent High-Temperature Strength: Maintains its structural integrity and resists creep and rupture at temperatures up to 1100°F (593°C) and beyond for the H/HT grades.
Outstanding Oxidation & Carburization Resistance: Resists scaling and degradation in oxidizing, sulfidizing, and carburizing atmospheres, making it ideal for furnace components.
Resistance to Various Corrosions: Performs well in aqueous corrosion, nitric acid, alkalies, and salts. It also resists chloride-induced stress corrosion cracking better than standard stainless steels.
Uniform Microstructure: The seamless process ensures consistent grain structure and mechanical properties around the entire circumference of the pipe

Applications

Due to its characteristics, 800/800H/800HT alloys are suitable for environments that require resistance to oxidation, carburization and other types of high-temperature corrosion. Seamless Incoloy pipes, including seamless high-temperature and high-pressure pipes, are widely used in these industries due to their excellent high-temperature and corrosion resistance.

Heat Treatment and Power Generation:

The excellent thermal stability and oxidation resistance of seamless Incoloy tubes ensure the service life of equipment in high temperature environments. 800/800H/800HT alloys are often used in applications exposed to high temperatures for a long time.
They are used in heat treatment plants, superheater and reheater tubes, manifolds, tail pipes, outlet manifolds and heating element jackets.

Chemical and Petrochemical Processing:

In chemical plants, these alloys are used to manufacture components exposed to corrosive environments.
Their ability to resist oxidation, carburization, and corrosion at high temperatures is critical in chemical processing plants.

Nuclear Industry:

800/800H/800HT alloys are used in steam generators and nuclear reactor components in nuclear power plants.
High temperature and corrosion resistance are critical to this industry.

Paper Pulp Industry:

Heat handling equipment such as baskets, trays and fixtures are often made from Incoloy 800H/HT.
These alloys help maintain the integrity of paper mill equipment.
