In-Line Pressure Balanced
Universal Hinged or Gimbaled
Expansion Joints

		`Eliminates pressure thrust and need for main anchors`

		`Reduces forces and moments on critical equipment`

		`No change of pipe direction required`

		`Absorbs axial, lateral and angular motions`

Hyspan has developed unique pressure balanced expansion joint designs that permit axial, lateral and angular movements without the necessity for main anchors to react the pressure thrust, or a change in direction of the piping. The Universal Hinge in-line pressure balance expansion joint permits axial travel, and lateral and angular motions in one plane. The Universal Gimbal permits axial travel, and lateral and angular motions in all planes.

The Hyspan design incorporates a bellows and linkage that reacts the pressure thrust within the expansion joint. The linkage is hinged or gimbaled depending on the desired motion.
