Inconel 800 Pipe and Tube

Inconel 800 pipe is a nickel-iron-chromium compound that was developed to offer high structural stability and strength when used in a high-temperature setting. This material is also characterised by resistance to oxidation and carburisation, as well as thermal fatigue, and is a reliable material that operates well in the harsh environment of industry. It is also known as Incoloy 800 pipe & tube or alloy 800 pipe (UNS N08800) and is a popular material in industrial piping systems, heat exchangers, furnaces, and petrochemical processing units.

Inconel 800 Pipe & Tube

Alloy 800 seamless pipe is used when there is a need to use high pressure and high temperature. These pipes are provided by trusted manufacturers of Inconel 800 pipes of different sizes and specifications, depending on the needs of the project. Inconel 800 pipeline pricing is also based on the size, specifications, and volume ordered, hence it is suitable for bulk supply as well as critical industry demands.

Seamless and Welded Inconel 800 Pipe Forms

Inconel 800 Seamless Pipe

Seamless pipes are produced either through extrusion or rotary piercing. The welded seam is nonexistent and they are therefore better suited in high pressure applications where uniformity of strength in the pipe body is imperative. They are usually utilized in high-performance heat transfer machinery.

Inconel 800 Welded Pipe

Welded pipes are made out of rolled and welded strips or plates. They are of lower cost in general than seamless, and come in larger diameter. These can be applied in environmental conditions of lower pressure and in structures.

Applications of Inconel 800 Pipe

The use of Inconel 800 is in the industries that need corrosiveness and high temperature:

  • Heat Exchangers: These are employed in tubing and piping of heat recovery systems.
  • Petrochemical Processing: This is necessary with cracker furnace tubes and pigtails.
  • Power Plants: Power plants are used in the superheater and the reheater tubing.
  • Furnace Systems: These are used in radiant tubes, muffles and retorts to treat heat.

Difference Between Inconel 800, 800H and 800HT Pipe

While they share the same basic composition, the differences lie in carbon, aluminum, and titanium levels to handle specific creep-rupture requirements.

  • Inconel 800: The general grade with carbon up to 0.10%. It is used for service temperatures up to 1100°F (593°C).
  • Incoloy 800H pipe: Features a controlled carbon content of 0.05-0.10% and a coarse grain structure for better high-temperature creep strength.
  • Incoloy 800HT pipe: Maintains the carbon control of 800H but requires a combined Aluminum and Titanium content of 0.85-1.20%.
  • ASTM B407 UNS N08811: This specific designation refers to the chemical and mechanical requirements for alloy 800HT pipe, ensuring maximum creep resistance.

Frequently Asked Questions About Inconel 800 Pipe

UNS N08800 is the Unified Numbering System designation for Inconel/Incoloy 800, defining its specific chemical composition of Nickel, Iron, and Chromium.

The primary standards are ASTM B407 for seamless pipe and tube, and ASTM B514 for welded pipe.

Seamless pipe is extruded and has no seam, offering higher pressure ratings. Welded pipe is made from rolled plate and is generally more economical for larger diameters.

Inconel 800 is generally used for service temperatures up to 1100°F (593°C). For higher temperatures requiring creep resistance, grades 800H or 800HT are recommended.

It consists of 30-35% Nickel, 19-23% Chromium, and the balanced Iron, providing excellent resistance to oxidation and carburization.
