How does the welded metal bellows seal work?

Date:Apr 15, 2020

Welded metal bellows seals are made by stamping a disc-shaped plate into a specific contour shape and welding in pairs at its inner diameter to form the folds of the bellows. Then a series of coils are stacked and welded on the outer diameter to form a bellows bladder. Appropriate end fittings can complete the assembly.
