flange cf
The flange cf is a critical component in vacuum systems and high-performance sealing applications, designed to create reliable, leak-tight connections between pipes, valves, and equipment. This specialized flange follows ConFlat (CF) standards, featuring a copper gasket sealing mechanism that ensures ultra-high vacuum integrity. The flange cf utilizes a knife-edge sealing surface that bites into a soft copper gasket, creating a metal-to-metal seal capable of maintaining vacuum levels down to 10^-13 mbar. The primary functions of the flange cf include establishing secure connections in vacuum chambers, facilitating easy assembly and disassembly of vacuum systems, and providing exceptional leak-tight performance in demanding environments. Technological features include precision-machined knife edges, typically manufactured from stainless steel 304 or 316L for corrosion resistance, and standardized bolt hole patterns that ensure compatibility across different manufacturers. The flange cf design incorporates a raised sealing surface with specific angles and dimensions that compress the copper gasket uniformly, eliminating virtual leaks and ensuring consistent performance. Applications span semiconductor manufacturing, particle accelerators, mass spectrometry equipment, research laboratories, aerospace testing facilities, and analytical instrumentation where ultra-high vacuum conditions are essential. The flange cf has become the industry standard for high-vacuum applications due to its proven reliability, reusability after proper gasket replacement, and ability to maintain seal integrity through multiple thermal cycles and mechanical stress conditions.
