Features Of Incoloy 800HT Welded Pipe
Oxidation Resistance
Incoloy 800HT welded tubes are particularly resistant to oxidation, even in environments with high temperatures and extreme pressure. These tubes have a high content of chromium, which forms a protective oxide layer on the surface of the metal that protects against heat and corrosion. The robust properties of Incoloy 800HT tubes make them favored for furnaces, thermo-wells, and other heat-intensive applications that require a high oxidation resistance.
Strength and Ductility
Incoloy 800HT welded tubes have excellent strength and ductility characteristics, making them ideal for use where high-pressure levels and temperature conditions are likely. Their high nickel content makes them particularly strong and resistant to deformation at high temperatures. On the other hand, their ductility characteristics help prevent cracks and leakages, increasing their durability.
Corrosion Resistance
Incoloy 800HT welded tubes exhibit a high resistance to corrosion in even the most challenging environments, making them the outstanding choice for petrochemical processing and other harsh applications. Their resistance to various acids and alkalis makes them a top pick in oil and gas companies, power generation, and chemical processing plants.
High-Temperature Resistance
A standout attribute of the Incoloy 800HT welded tubes is their heat resistance. This alloy can withstand temperatures up to 871°C (1600°F) without significant degradation, making them an excellent choice for high-temperature applications such as heat exchangers, steam generators, and radiant tubes.
