We fabricate these CF flanged edge-welded bellows for UHV systems from 347 stainless steel hoses and 304L stainless steel knife-edge (ConFlat) flanges. In contrast to hydraulically formed metal hoses, edge-welded bellows are very flexible and tend to spring back to their natural length (typically midway between their extended and compressed lengths) when not under vacuum. The CF flange is the most widely used for high vacuum and UHV applications. Many gauges, instruments, accessories and feedthroughs are available on this flange system.
Edge-Welded Bellows Feature:
- Very flexible
- Spring-back to their natural length when not under vacuum
- The maximum bakeout temperature for the Stainless Steel Bellows is 250°C
