The expansion joints are elements buit, in their main part, by a mono or multi-layer bellows, which allow to absorb axial, angural, lateral movements.

They can also be used to absorb vibrations in engines or machineries applications.

Inox bellows, singular o multi-layer, are built by a stainless steel coil, longitudinally welded in TIG.
Otherwise they are in EPDM, NBR, VITON o PTFE

Expansion joins are used in cold or warm water plants, steam, diatermic oil, air-condition systems, and in all other situations where you ave to absorb movemens and vibrations.
