This expansion joint is made up of a single bellows with sleeves, that allow BIKAR to produce it at the required length. It can absorb movements in any direction, axial, angular and lateral.
It is mainly used to absorb axial dilations in longitudinal direction of straight piping systems, although depending on their design it can absorb small quantities of angular and lateral movements. It is the most straightforward type, although the piping must be controlled (anchored and guided) so the movements foreseen are conveniently directed to the right direction for correct operation.
This design cannot withstand pressure forces and must be supported by duly designed fixed anchorages.
Characteristics and Properties
Absorbs large lateral and axial movements.
Allows angular movements.
Does not retain the force of the pressure.
Must be properly anchored and guided.
Does not resist the force of the pressure, and must be supported by fixed anchoring that is properly designed.
