Short answer: Metal bellows are thin-walled, convolute flexible elements made by hydraulically forming a tube, welding stacked rings, or pressing a blank — absorbing axial, lateral and angular movement while sealing pressure and isolating vibration. Used in expansion joints, flexible couplings, actuators and hermetic seals, bellows let piping and instruments flex under thermal growth, misalignment and pressure without fatigue failure, with stainless and Inconel chosen for corrosion and temperature service.
