How to choose a vacuum flange

  1. The material leakage rate and gas outlet rate should be small. Many vacuum applications have requirements on the leakage rate of the vacuum system, so the leakage rate and air outlet rate of the vacuum flange material should be as small as possible.
  2.  Vacuum leak detection is convenient. In the introduction of leak-prone parts in the vacuum system, the screw vacuum pump manufacturer mentioned that the vacuum flange and various sealing joints are some of the leak-prone parts. Therefore, the selection of vacuum flanges should be conducive to the development of vacuum leak detection.
  3. Good thermal stability and repeated short-term heating will not damage air tightness.
  4. The ability to maintain air tightness after repeated disassembly and assembly. At this point, most of the sealing rings of metal sealing flanges can only be used once, but the emergence of metal elastic sealing rings is especially suitable for the sealing of metal ultra-high vacuum valves.
