WHAT ARE EDGE WELDED METAL BELLOWS?
As the name implies, Edge Welded Metal Bellows are composed of thin foil metal stampings that are welded together on the inner diameter (ID) & outer diameter (OD) edges to create a flexible hermetically sealed assembly.
The uses of this component are only limited by engineering imagination.
Application Engineers use Welded Bellows when flexible solutions are needed for:
SEALING, SENSING, COMPENSATING, DISPLACING, CONNECTING, DAMPENING, ACTUATING
The “ripple” shape and thickness of individual diaphragm foil stampings consider the pressure and bending stresses required of the assembly along with its duty cycle, environment, and application use.
WHAT ARE PRODUCT ADVANTAGES?
The uses and end products for KSM Edge Welded Metal Bellows can be found in almost every market, where there is a need for:
- Hermetic sealing on ID & OD to separate hazardous environments
- Suitable for use with most fluids and gases
- Compact assembly – achieving flexibility and movement in a short space
- All metal construction – to work in extreme temperatures and/or corrosive environments
- Wide range of motion – axial, angular, or lateral
- External pressure capability – especially at solid height
- Ability to easily join [weld or braze] to mating machined components
All welding and assembly of KSM bellows products is performed in a Class 6 (1000) Clean Room; with Final Inspection, Cleaning, and Packaging in a Class 5 (100) environment. Our clean manufacturing process meets the most stringent market requirements.
