Metal Expansion Joint

Gimble Expansion Joint
  • Permits angular movement in any plane
  • Eliminates pressure thrust forces
  • No main anchors required
  • Transmits loads, so low forces on the pipe anchors
  • Prevents torsion or twisting of the expansion joint
  • .
  • Internal flow liners for eliminating velocity problem
  • Anchors only required to absorb spring forces

Gimbal expansion joint is designed to permit angular rotation in any plane by the use of two pairs of hinges affixed to common floating gimbal ring. This expansion joint can consist of a single bellow, where there is no lateral deflection, or two bellows connected by a common connector/pipe spool where it can permit a lateral deflection also. The gimbal ring, hinges and pins must be designed to restrain the pressure thrust loads and other external loads such as dead weight and wind.
