The bellows is the fundamental part of the expansion joint, and it is obtained by hydraulic or mechanic trial from stainless steel or alloy steel having only one longitudinal welding. A controlled behaviour produces a set of parallel metallic waves, that ensure maximum flexibility and reliability..
Our system of calculation furnishes the stressanalysis of the bellows, which allows to make calculations according to customer's specifications.
