The flexible element of any Expansion Joints consisting of one or more convolution, with or without reinforced ring and the end tangents with minimum 5mm with no more than FIVE plies, that is call Bellows Element.

There are so many type of Expansion Joints use in industry and to make the complete assembly of Expansion Joints, need ONE or more Bellows Element. Bellows Expansion Joints are employed in piping systems to absorb differential thermal expansion while containing the system pressure. They are being successfully utilized in refineries, chemical plate, fossil and nuclear power systems, heating and cooling systems, and cryogenic plates.
