 Axial expansion joints stainless steel Witzenmann
HYDRA® Axial Expansion Joints

Axial expansion joints for the absorption of axial movements, i.e. movements along the expansion joint.

  • axial movement absorption of up to approx. 200 mm possible
  • low absorption of lateral and angular movements possible
  • unanchored: movement on all sides possible. High axial forces in conjunction with high pressure

 Universal expansion joints stainless steel Witzenmann
HYDRA® Universal Expansion Joints

Universal expansion joints comprise two metal bellows interconnected by a central tube.

  • absorption of axial, lateral and angular movements possible
  • unanchored: movement on all sides possible. High axial forces in conjunction with high pressure

Lateral expansion joints
HYDRA® Lateral Expansion Joints

Lateral expansion joints are suitable for the absorption of lateral movements, i.e. transversely to the pipe axis of the expansion joint.

  • absorption of lateral movement
  • one-way flexibility with single pivot bolt bracing
  • universal flexibility with cardan joint bracing
  • bracing for absorbing the axial compressive forces (no axial movement possible)

 Angular expansion joints stainless steel Witzenmann
HYDRA® Angular Expansion Joints

Angular expansion joints absorb movements in the form of angular movements.

  • absorption of angular movements
  • one-way flexibility with single pivot bolt bracing
  • mobility in all directions with tie rod bracing or cardan joint bracing
  • bracing for absorbing axial compressive forces (no axial movement possible)
