Adinox Overseas is a prominent supplier and exporter of highest-grade Incoloy 800HT Tubes, developed to deliver peak performances under conditions of high temperature and pressure. Incoloy 800HT, also known as UNS N08811, is a more advanced form of Incoloy 800H and exhibits enhanced strength, structural integrity, and resistance to oxidation. These tubes are specifically made in conformation to strict specifications such as ASTM B407 and ASTM B514 standards to make them suitable for challenging thermal processing and chemical plant process demands.
The chemical makeup of Incoloy 800HT (UNS N08811) Tubes consists of a well-balanced alloy of nickel, iron, and chromium, which exhibits superior resistance to carburization, oxidation, and sulfidation. The increase in higher carbon, aluminum, and the content of titanium strengthens its ability to resist creep and rupture, particularly in temperatures over 600°C. This in turn makes Incoloy 800HT suitable for heat exchangers, furnace fittings, hydrocarbon cracking units, and petrochemical processing equipment.
Alloy 800 Tubes is their resistance and ability to retain their strength in temperatures up to 1100°F or 593°C. They are great in terms of structural stability when exposed to high temperatures over a prolonged period and do not lose their metallurgical integrity, even in extreme industrial environments.
Adinox Overseas provides seamless tubes in Incoloy 800HT that are accurately manufactured using cold-drawn or hot-finished processes to maintain uniform wall thickness, dimensional consistency, as well as enhanced mechanical strength. Our incoloy 800HT welded tubes are made using qualified filler materials and rigorous welding procedures to provide total corrosion resistance and strength in structure even with extended elevated temperature exposures.
We make sure that all our Incoloy 800HT tubes adhere to industry standards such as ASTM B407, ASTM B514, and ASME SB407/SB514. All tubes go through complete quality inspection, which includes hydro testing, eddy current testing, ultrasonic testing, and third-party inspection, in addition to full mill test certification for complete traceability. The tubes are made to exact customer requirements in terms of length, diameter, and wall thickness by our technical team.
