A105 RF Blind Flange is a type of forged carbon steel flange designed in compliance with the ASTM A105 specification and featuring a Raised Face (RF) sealing surface. This flange is used to close the end of a piping system or a pressure vessel opening, effectively stopping the flow of fluid. The raised face helps concentrate the gasket pressure in a smaller area, creating a tight and reliable seal. A105 RF Blind Flanges are ideal for high-pressure and high-temperature services and are commonly used in industries like oil & gas, petrochemical, power generation, and offshore drilling.
