Bikar - Model BM-EX-SI -Metal Expansion Joint with Welding Ends
This expansion joint is made up of a single bellows with its connections. 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.
- The most economical expansion joint
- Does not retain the force of the pressure
- Absorbs axial, lateral, and angular movements
- 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. Otherwise, the joint may become overextended, with disastrous consequences.
