These bellows accumulators, used to store the energy of a liquid or gas, can be manufactured in small sizes with added stroke-length capability. Their edge-welded metal bellows consist of nested rippled diaphragms that can completely collapse onto themselves as well as expand to 25% of their free length. The bellows assembly can be pressurized internally or externally. The accumulators are available in 316L stainless steel, titanium, and nickel alloys. Standard diaphragm sizes range from less than 1/2 in. to over 2 ft in diameter, but may also be manufactured to customer specification. Guides and over-travel stops may be added to the assembly to protect against pressure transients.
