Metal bellows (generally called: elastic element) are formed through hydraulic pressure by stainless steel and other thin-wall metal pipes. The products have such advantages as high sensitivity, reliable performance and long serving life. The products are widely used in such areas as metallurgy, machinery, petrochemical, textiles, electric power, and shipbuilding. They can be used as sensing elements in pneumatic instruments and electrodynamic instruments, and as sealing elements in the vacuum switches, bellow valves, and mechanical equipment and accessories. As a transmission element in the coupling, they play the role of compensation and pneumatic accessories in the piping system.
