C276 flanges are a nickel alloy grade best suited for high temperature applications such as oil and gas, aerospace and other industries.Hastelloy C276 flanges are plate flanges used in fuel and water pipelines. It has greater thermal stability. It is used to connect other threaded components that operate at low pressures and environments.C276 blind flanges are used to block off one part of a pipe so that no fluid or liquid can pass through from the other end. This has a corrosive effect of wet chlorine gas, hypochlorite and chlorine dioxide. The materials used are of high quality and the manufacturing process is handled in a proper manner.
Characteristic of ASTM B462 C276 Flange
Corrosion resistance: ASTM B462 C276 flanges are able to resist corrosion from various strong acids, alkalis and brines, including sulfuric acid, hydrochloric acid, nitric acid, chlorides and so on.
High-temperature performance: C276 alloy has good high-temperature strength and oxidation resistance, and can operate stably for a long time in high-temperature environment.
Resistance to stress corrosion cracking: C276 alloy has excellent resistance to stress corrosion cracking and is suitable for use in conditions where both stress and corrosive media are present.
WIDELY USED: ASTM B462 C276 flanges are widely used in chemical, petroleum, pharmaceutical, food processing and other industries for manufacturing corrosion-resistant pipe connections.
