Alloy C276 pipe is made from a nickel-molybdenum-chromium alloy with tungsten addition that has good corrosion resistance in various harsh situations. Because of the high molybdenum content, this alloy is particularly resistant to pitting and crevice corrosion. The low carbon content reduces carbide precipitation during welding, preserving corrosion resistance in as-welded structures.
In a range of severe conditions and media, Alloy C-276 has exceptional corrosion resistance. It’s ductile, like many other nickel alloys, and can be easily shaped and welded. In most industrial applications where harsh chemical conditions exist, and other alloys have failed, this alloy is used.
The pulp and paper business employs wood as a key raw resource to produce high-quality pulp, paper, and other cellulose using the proper bleaching vessels and digesters. Wood pulp is bleached when you use the bleaching vessels, and the strongest appears whiter. On the other hand, Digesters are made of wood chips burned to a high temperature with sodium hydroxides and even sodium sulfide to modify the pulp by dissolving the lignin binder dramatically. White and back liquors are corrosive substances in cooking that can damage the wall of the interior parts.
Chloride, as well as chlorine-dependent compounds, are used in the above process. On the other hand, Hastelloy alloy c276 pipe and tube develop first-class corrosion resistance in the great majority of chloride environments. It has both acidic and alkaline properties, making it the optimum choice for vessel bleaching and digester content.
What is Hastelloy?
Nickel-molybdenum alloy Hastelloy is a nickel-molybdenum alloy. Hastelloy comes in a variety of grades, several of which are nickel-chromium-molybdenum alloys. Each of these grades has been tailored for a distinct application, although they are all corrosion-resistant. Hastelloy is made tougher by molybdenum, which makes it stronger at high temperatures and ideal for welding. These alloys are simple to work with and form. They may be forged, and cold worked, and have high ductility.
Hastelloy is a suitable choice for moderate to severe corrosive conditions because of its remarkable resistance to severely oxidizing and reducing chemicals. In the chemical processing and petrochemical industries, it is often used for pipes and valves. It’s also great for pressure vessels and heat exchangers, and it’s utilized in nuclear and chemical reactors.
Industries and applications of c 276 alloy
Chemical and petrochemical processing, oil and gas, power generating, pharmaceutical, pulp, paper production, and wastewater treatment are just a few industries that use alloy C-276. Stack liners, ducts, dampers, scrubbers, stack gas reheaters, heat exchangers, reaction vessels, evaporators, transfer pipework, and many other highly corrosive applications are among the end-use applications.
Because C276 pipe comes in various shapes and sizes, including bar, plate, pipe fittings, welding wire, pipe, and tube, it would be easier for industries to use it for a variety of purposes. It refers to the number of corrosion-resistant flexible alloys available on the market. It offers great resistance to a wide range of chemical processes, including ferric and cupric chloride, hypochlorite, and other brine, without posing any harm. It has a low carbon content, which helps prevent grain boundary carbide precipitation during welding, preserving the heat component of the welded joints’ corrosion resistance. This resistance is against localized cracking, pitting, and stress corrosion cracking, among other things.
