cf blank flange
The cf blank flange is a critical sealing component designed for ConFlat (CF) vacuum systems, providing reliable vacuum-tight closure for unused ports and openings. This specialized flange features a solid, non-drilled design that effectively seals vacuum chambers, research equipment, and industrial systems operating under ultra-high vacuum conditions. The cf blank flange incorporates a knife-edge sealing surface that works in conjunction with copper gaskets to create leak-tight seals capable of maintaining pressures down to 10^-12 torr. Manufactured from high-quality stainless steel, typically 304 or 316L grades, these flanges offer exceptional corrosion resistance and durability in demanding environments. The cf blank flange serves multiple functions including port closure during system configuration changes, protection of sensitive internal components from contamination, and facilitation of flexible system design by allowing unused connections to be sealed temporarily or permanently. Available in standard sizes ranging from small 1.33-inch to large 16.5-inch diameters, the cf blank flange accommodates various system requirements and port configurations. The technological features include precision-machined knife-edge geometry, mirror-polished sealing surfaces, and strict dimensional tolerances conforming to international vacuum standards. Applications span across semiconductor manufacturing, particle accelerators, mass spectrometry equipment, surface science research, thin-film deposition systems, and aerospace testing facilities. The cf blank flange represents an essential component for maintaining system integrity, enabling easy reconfiguration, and ensuring optimal vacuum performance in both research and industrial settings where contamination control and leak-free operation are paramount.
