CF Blank Flange with Tapped Bolt Holes
A CF blank flange is a type of vacuum flange that is used in high vacuum applications. CF, which stands for ConFlat, is a type of vacuum flange standard commonly used in the design and construction of vacuum systems. The CF blank flange is a component that is used to seal off an opening in a vacuum system, typically a connection port that is not in use or needs to be closed temporarily.
The CF flange system is known for its high vacuum integrity and is used in applications where a reliable and leak-free vacuum seal is essential. The CF blank flange is designed to be bolted onto a mating CF flange using a knife-edge seal and copper gasket to ensure a secure and gas-tight seal. high-quality materials such as stainless steel or other vacuum-compatible alloys to maintain the integrity of the vacuum system.
CF blank flanges are available in various sizes to accommodate different port diameters and are an essential component in the construction and maintenance of seal off unused or temporary openings to maintain the vacuum integrity of the system.
The CF (ConFlat) standard is a common flange standard for high vacuum systems, with features including knife-edge sealing and bolt fixing. The CF screw hole blind flange design meets this standard and is available in different specifications to match CF flanges of different diameters. The use of CF screw hole blind flanges can effectively close unused flange ports to ensure the integrity and performance of the vacuum system.
It is suitable for vacuum systems in laboratories, industry and scientific research fields and is an important component for changing connection configurations or performing system closure maintenance.
