Hastelloy is a nickel based material that shows very high resistance to corrosion. The alloy contains chromium and molybdenum which enhances the properties. Hastelloy screwed flange shows great performance in both oxidizing and reducing environments, along with different corrosive media. They show exceptional resistance to both sulphuric and hydrochloric acids. Due to its properties, reputed Hastelloy flanges manufacturers recommend the products for chemical processing applications, especially the C276 grade.
The Hastelloy flanges have their standard sizes ranging between ½ to 12”. They are available with different standards & specifications and pressure classes from PN6 to PN 64 and higher. The Hastelloy orifice flange is easily customizable and they can be manufactured as per application requirements. They come in different types for serving varied piping operations. The Hastelloy plate flange has low thermal stability and can be used in waste management technologies.
The Hastelloy blind flange can be used to close the end of a piping system for permanent or temporary sealing. It can be used during pressure testing or if there is a plan for future expansion of the piping system. The Hastelloy spectacle blind flange can also be used for maintenance or repair purposes and it can block piping equipment too like valves, pumps, etc. These can also be considered as safety devices that can reduce the risk of leaks and spills.
