Why an Edge Welded Metal Bellows ?

The importance of design cannot be over emphasised

It is not unusual to encounter applications requiring design life of 5,000 to 1,000, 000 cycles that often have lateral movements and/or tilt that are under pressure or vacuum and where temperature effects, contact with aggressive chemicals or gasses may need to be considered, or where space is at a premium.

For meeting these constraints an Edge Welded Bellows has many design advantages. It is possible to design a bellows that completely meets all the requirements of your application by  specifying the correct diaphragm diameters, diaphragm profile, bellows pitching as well as material type,thickness/ply, number of convolutions, heat treatment etc.

We regularly manufacture in Inconel, Hastelloy, AM350 and 316L stainless steel should the design require it.

Please contact us for design advice we are always happy to help.

It is expertise and experience that brings results quickly!

Refining Bellows Designs

Flexiblity throughout the design and development

An important feature of Edge Welded Bellows is the ability to change materials and thickness at any point after the initial design and to do this without incurring expensive re tooling costs. Refining your bellows application should never be a price barrier.


The design has changed during the development? No problem!

Testing and UHV standards

Testing under pressure or vacuum, internal or external .

When verification is required our bellows test rig is available. We can fatigue test the limits of a design sample under simulated operating conditions.

Cleaning to meet the exacting standards or Ultra High Vacuum.

Not all our bellows require UHV cleaning. When this is a requirement our fully equipped clean room area includes an ultrasonic cleaning tank,vacuum drying oven and laminar  flow cabinet. We offer bellows that meet the exacting requirements of Ultra High Vacuum standards.

Design assurance testing for critical applications, UHV cleaning.
