BellowsTech LLC has released its metal bellows accumulators, which are used to store the energy of a liquid or gas. Bellows accumulators using edge welded bellows can be manufactured in smaller sizes with added stroke length capability.
Edge welded bellows are comprised of nested rippled diaphragms, so they are capable of completely compressing onto themselves. Edge welded bellows can also expand up to 25% of their free length.

The bellows assembly can be pressurized both internally and externally. With a variety of material options including 316L stainless steel, Inconel, Hastelloy, and titanium, BellowsTech can manufacture bellows accumulators for a variety of liquids and gases. The standard diaphragm sizes are from less than half an inch to over two feet in diameter.
The Company uses in-house machining to manufacture tools and dies. Special guides and over-travel stops can be added to the bellows assembly to protect against pressure transients.
Through BellowsTech’s value added services, external housings can also be installed to make the accumulator a complete assembly. Design of the accumulator assembly can be completed through an online design form or a downloadable PDF form.
