Incoloy 800, Incoloy 800H, and Incoloy 800HT are nickel-iron-chromium superalloys that offer exceptional resistance to high-temperature environments and corrosive conditions. These alloys are widely used in various industries, particularly in applications involving heat and pressure, where buttweld fittings play a crucial role in connecting and joining pipes or tubes. Incoloy 800, Incoloy 800H, and Incoloy 800HT Buttweld Fittings are specifically designed to meet the stringent requirements of such demanding environments.
Incoloy 800 is the basic grade of this family and offers excellent resistance to oxidation, carburization, and other forms of high-temperature corrosion. It is commonly used in furnace and heat exchanger applications, as well as in chemical and petrochemical processes.
Incoloy 800H is an enhanced version of Incoloy 800, with higher carbon content. This modification provides improved creep and rupture strength at elevated temperatures. Incoloy 800H is often chosen for applications where extended exposure to high temperatures is a concern, such as in power generation and thermal processing industries.
Table Of Content
Incoloy 800HT takes the properties of Incoloy 800H to the next level. It has even higher levels of nickel and chromium, further enhancing its high-temperature resistance and mechanical strength. Incoloy 800HT is particularly suitable for applications in extreme heat, like in the production of industrial furnaces and heat-treating equipment.
Incoloy 800, Incoloy 800H, and Incoloy 800HT buttweld fittings are precision-engineered components used to create leak-tight connections in pipelines and systems. These fittings come in various forms, including elbows, tees, reducers, and caps, allowing for flexibility in designing and constructing complex piping systems.
Key features of Incoloy 800, 800H, and 800HT buttweld fittings include:
Corrosion Resistance: These fittings provide exceptional resistance to corrosion, making them suitable for environments where acids, alkalis, and other corrosive substances are present.
High-Temperature Strength: The alloys offer excellent mechanical strength and creep resistance at elevated temperatures, ensuring the integrity of the connections even in extreme heat.
Weldability: Incoloy 800, 800H, and 800HT buttweld fittings can be easily welded, facilitating the installation and maintenance of piping systems.
Longevity: The superior corrosion resistance and high-temperature capabilities of these alloys make the buttweld fittings highly durable and long-lasting, reducing the need for frequent replacements.
