Pressure Balance Expansion Joint

The PBEJ is design in single or Dual Expansion Joint and its can absorb axial and lateral movement. Single or Double line bellows assembly connected with the balancing bellows using devices call tie rods or bars to restraining the axial and compressive thrust force due to internal pressure and its can allow free to move for lateral movement. Also supporting the dead weight of the balancing bellows and blind flange or dished ends. Each bellows set is designed to absorb the axial movement and usually the line bellows absorb lateral deflection.
