Inconel 800H/800HT Welded Pipes Manufacturer, Stockists,
Supplier and Exporter in Mumbai, India.

What are Inconel 800H / 800HT Welded Pipes?

Inconel 800H / 800HT Welded Pipes are high-performance nickel-iron-chromium alloy pipes designed for high-temperature service. These alloys are modified versions of Alloy 800, developed to provide improved creep strength and enhanced resistance to thermal fatigue in extreme conditions.

Incoloy 800H contains controlled carbon and grain size that improve its mechanical strength at elevated temperatures. Incoloy 800HT, on the other hand, offers even higher creep rupture strength due to tighter control of aluminum and titanium content.

Our manufacturing range includes:

•   Incoloy UNS N08810 / N08811 Weld Pipe
•   Alloy 800H ERW Hollow Pipe
•   Alloy 800H ERW Pipe
•   Incoloy 800H welded pipes
•   Incoloy 800 Ht ERW Pipes
•   Alloy 800ht Welded Pipe
•   Incoloy Alloy 800ht Welded Pipe
•   ASME SB514 Nickel Alloy 800HT Welded Pipes

These pipes are manufactured through high-precision welding processes such as ERW and EFW to ensure excellent dimensional accuracy and strong weld integrity.

Key Features of Incoloy 800H / 800HT Welded Pipes

•   Excellent High Temperature Strength: Alloy 800ht Welded Pipe offers exceptional creep rupture strength at elevated temperatures, making it suitable for long-term high-heat applications.
/strong> and Incoloy 800HT (UNS N08811) provide excellent resistance to oxidation and scaling in high-temperature environments.
•   Superior Oxidation Resistance: The high chromium content provides strong resistance to oxidation and scaling even in aggressive environments.
•   Outstanding Structural Stability: The controlled grain structure of Incoloy UNS N08810 / N08811 Weld Pipe ensures dimensional stability under thermal stress.
•   Resistance to Corrosive Media: These welded pipes offer excellent resistance to carburization, nitriding, and sulfur-containing atmospheres.
