Hastelloy Flanges Manufacturer and Supplier In India

Hastelloy is a trademarked name for a family of high-performance, corrosion-resistant nickel-based alloys. These alloys are known for their excellent resistance to a wide range of corrosive conditions, making them highly suitable for applications in aggressive chemical processing, petrochemical, and other industries where corrosion resistance is very necessary. Hastelloy flanges are specialized flanges made from Hastelloy alloys. These flanges are manufactured to connect pipes, valves, and other equipment in a piping system while providing the same corrosion resistance as the base Hastelloy material. Hastelloy flanges are parts used in piping systems to simplify the assembly, disassembly, and maintenance of pipelines. They are normally circular discs with openings in the center to hold the pipe or valve they are attached. These flanges are made from various grades of Hastelloy alloys, such as Hastelloy C-276, Hastelloy C-22, and Hastelloy B-2, to match the specific corrosion resistance requirements of the application. Some of the advantages of hastelloy flanges are high corrosion resistance, high strength, excellent durability and low maintenance. Various applications where these flanges are used are pollution control, offshore and marine, semiconductor industry, petrochemical industry and many more.
