Hydroformed bellows

Hydroformed Bellows


Metal bellows, also known as expansion joint and elastic element, is made of ultra-thin precision metal tube (seamless, slit), and shaped by hydraulic forming.


Using the elastic properties of metal bellows, the measurement pressure signal can be transformed into the displacement parameters or concentrated force parameters.


Also, it can be used as isolation components, sealing components, connecting components, compensating element and other applications.


Metal bellows is widely used in pressure controller, temperature controller, pressure transducer, measuring instrument, pressure control valve, flow control valve, relief valve and pipe connection in the products such as pressure compensator and temperature compensator.


It also can be used in mechanical components field serve as various couplings and medium isolator.
