Vibration Absorbers

Metal expansion joints can also be used to absorb vibration in systems. They are manufactured from thin, multi-layer bellows for excellent vibration absorbing capabilities. Multi-layer bellows help to dampen high frequency and low amplitude vibrations. While vibration absorbers are mostly used with flanged connections, they can also be supplied with welded connections.

A very typical accessory with this type of expansion joint is a limit rod / tie-rod to restrain pressure thrust of bellows or limit excessive design movements.

Metal expansion joints is an excellent choice for absorbing vibrations where temperatures or pressures are too high for rubber expansion joints. Rubber washers can be used to reduce noise.

Advantages of Vibration Absorbers

They are designed for versatile usage in any system where pump vibrations occur.
Standard range is made from multi-ply bellows with several very thin layers of stainless steel.
Pressure and temperature bearing capacity, noise and vibration absorption and overall cyclic service life.
Range of vibration absorbers can resolve many problems related to mechanical vibration and have a higher pressure and temperature rating than rubber bellows.
Rubber bushes can be added on the tie rods to help reduce the noise.
