Flanges and Fittings

Description:

Flanges and Fittings play crucial roles in the construction and operation of vacuum systems. They provide means for connecting different components, chambers, and instruments within the vacuum system while maintaining a high vacuum or
ultra-high vacuum environment.

Some details about fittings and flanges commonly used in vacuum systems:

  • Flanges: Flanges are flat, typically circular plates with bolt holes around the perimeter. They are used to connect vacuum chambers, components, and instruments together. Flanges come in various sizes, shapes, and materials to accommodate different vacuum system requirements. Common materials for flanges include stainless steel, aluminum, and glass.
  • Fittings: Fittings are components used to connect different vacuum system elements such as vacuum pumps, gauges, valves, and chambers. They come in various shapes and sizes to accommodate different vacuum system configurations. Common types of fittings include elbows, tees, crosses, reducers, and adapters.
Description

Types of Flanges:

1. KF (Quick-Flange)
2. CF (Conflat)
3.1 ISO-K
3.2 ISO-F
Materials: Fittings and flanges used in vacuum systems are typically made from materials that are compatible with vacuum conditions and do not outgas or contaminate the vacuum environment. Common materials include stainless steel, aluminum, brass, and certain plastics such as PTFE (polytetrafluoroethylene).
Sealing: Proper sealing is essential for maintaining vacuum integrity in a vacuum system. Flanges and fittings utilize different sealing mechanisms such as elastomeric O-rings, metal gaskets, or knife-edge seals depending on the vacuum level and application requirements.
