WELDED BELLOWS Eagle Engineering Aerospace welded metal bellows are comprised of a series of alternately welded stamped discs or plates. The final welded assembly is called a bellows core. The final product is a hermetically sealed, flexible, temperature resilient device. Depending on the final application for the bellows device, the plates are configured with various shapes: nested ripple, flat ID, coned ID, cantilever, multiple ply, etc. Welded bellows can provide a high pressure capable accumulator or bellows reservoir. Welded bellows can satisfy a wide range of requirements including: corrosion resistance, high and low ( cryogenic) temperature , high and low pressure, long axial or angular deflections, compatibility with hazardous gases or liquids. HYDROFORMED BELLOWS Hydroforming can produce tubular parts with a wide range in geometry and cross-sectional shape that can vary continuously throughout the length of the part. However, EEA has developed a new technology to manufacture complex shaped bellows by using a single flat round plate for forming. This allows us to produce uniform composite bellows and has got an advantage in the aerospace application where uniformity is very important for air-worthiness. Our hydroformed bellows is used in the temperature and pressure sensors in jet engine fuel controllers. APPLICATION Welded metal bellows allow them to be applied in a wide array or aerospace and industrial devices such as: Actuators, accumulation or volume compensation, bellows mechanical sealing ducting, expansion joints, flexible sealing pressure sensing, temperature sensing, vacuum management. SPECIAL APPLICATION Hermetically sealed welded metal bellows accumulators are "maintenance" free and are excellent replacements for bladder and piston type accumulators that are in hard to reach areas for regular maintenance. This advantage of maintenance free and it's versatility against severe aerospace circumstances was successfully admitted in the Japanese space station and has been widely used in many type of accumulators.
