Industrial Applications And Chemical Composition Of Inconel 800 Tubes



Inconel 800 tube
Inconel 800 alloy and industrial equipment made from it like tubes, pipes, fittings, etc. are used in a variety of industrial applications because of its unique heat resistance and corrosion resistance benefits. The Inconel 800 tubes are used in heat exchangers and in other kinds of piping systems in the chemical processing industry. In petrochemical industries and refiners, where there are high chances of chloride ion caused stress corrosion and cracking, the tubes offer excellent corrosion resistance. The corrosion resistance of the alloy is intact even in systems that have media containing nitric acid. The tubing of steam generators is made of Inconel 800 alloy, in the nuclear power plants. The electrical heating elements of many of the domestic application are sheathed by Inconel 800 as it provides for heat resistance and corrosion resistance. The liquor heaters and other systems of the paper and pulp industry are often made up of the alloy. The alloy tubes, fittings, etc. are also used in the petroleum processing industry for making the heat exchangers and can cool the air that processes steam.
Chemical composition of the alloy
The alloy contains various elements that combine together to provide the Inconel 800 tubes its required strength and corrosion resistance. The Inconel 800 tube manufacturers pass the tubes through different mechanical, physical and other quality tests to judge them for their qualities and performance.
The alloy has 30 to 35 % of nickel, 19 to 23% of chromium, 39.5% of iron (minimum), 1% of silicon (maximum), 0.10% of carbon, 0.75%of copper, 0.15 to 0.60% of aluminum and 0.15 to 0.60% of titanium. The alloy and tubes have higher mechanical strength than other alloys. The tubes can be used for their strength characteristics up to a temperature of 1500 degree Fahrenheit. Some applications require even greater creep and rupture strength. For these kinds of application, the reformed Inconel 800H and Inconel 800HT alloys are used.

  1. It was very useful post and the INCOLOY alloy 800 is subjected to warmth from additional or welding procedures, treatment ought to be taken up to prevent sensitization when the substance will be pickled or put through other intense conditions. Sensitization isn't an issue in many high temperature applications.. Thanks for Posting incoloy 800 tube | incoloy 800 tube
