Important components of vacuum engineering are flange parts. These include components of vacuum systems, which are necessary to set up vacuum pipe-systems, e.g. flanges, seals, bellows and customized pipe-parts (elbows, T-fittings, spider bodies etc.). The employment in vacuum engineering leads therefore to high requirements on both the choice of materials and the manufacturing of these components. For different areas of application different connecting standards exist, which are based on different flange systems. Therefore vacuum components of JUST VACUUM are available in all important standards. Our delivery program contains a large selection of standard vacuum parts. Beyond that we are specialized to manufacture customized vacuum components according to your requirements. Flange systems (KF, ISO-K, CF) |
