Flex Metal Bellows — Edge Welded with Tube Ends

We fabricate these tube end (tubulated) edge-welded bellows for UHV systems from 347 stainless steel hoses. 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.

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

  • UPS will deliver a maximum length of 8'. Lengths over 8' require special packaging and shipping (motor freight) at an additional nominal cost. Customer can approve other packaging/shipping methods.
  • The compressed and extended lengths in the table below does not include the tube ends. The bellow's stroke can be calculated by subtracting the compressed length from the extended length. The free (relaxed or natural) length is approximately equal to the stroke. The Bellows should not be compressed or extended beyond the recommended length.
