Rectangular Bellows
The key performance indicators for bellow are reliability and variability. We fabricate these Rectangular Bellows for FV, HV, UHV and XHV systems from 347 stainless steel hoses and 304L stainless steel. Rectangular bellows are flexible and tend to spring back to their natural length (typically midway between their extended and compressed lengths) when not under vacuum. All kinds of flange are the most widely used for FV, HV, UHV and XHV applications. Many gauges, instruments, accessories and feedthroughs are available on this flange system.
