Energy storage industry bellows welding

What are edge welded metal bellows?

Because edge-welded metal bellows are manufac-tured by welding both the inner and outer diameters of the bellow plates, they can be produced in a broader variety of materials than formed bellows, in which the number and shape of the bellows convolutions are limited by material ductility.

What is the lowest temperature our edge-welded bellows can maintain?

Our edge-welded bellows can maintain temperatures as low as -95°C. Edge-welded metal bellows are a trusted, reliable solution for NASA cryogenic temperature chambers.

What can metal bellows withstand?

Metal bellows produced using the edge-welding process can be exposed to liquid and gaseous elements and are highly durable in extreme temperature and pressure environments. They allow for the highest stroke length, reaching 90% of its free length.

What kind of pressures can edge-welded bellows hold?

Edge-welded bellows can hold ultra-high vacuum or moderate positive pressures. In semiconductor and ultra-high vacuum (UHV) manufacturing, they are used as flexible penetrations into process chambers, becoming part of the pressure wall of the chamber while providing motion inside the chamber.

Are edge welded bellows a reliable solution for NASA cryogenic temperature chambers?

Edge-welded metal bellows are a trusted, reliable solution for NASA cryogenic temperature chambers. They can maintain temperatures as low as -95°C, requiring more design and expertise than typical refrigeration applications.

Why are edge welded bellows used in semiconductor & UHV manufacturing?

In semiconductor and ultra-high vacuum (UHV) manufacturing, edge-welded bellows are used as flexible penetrations into process chambers.
