This metal expansion joint is made of a single bellows with its connections, to which control rods are attached. The installation of control rods designed to support the force of the pressure, and attached using projections on the pipes or flanges, can eliminate the need for fixed anchoring.
Characteristics and Properties
Eliminates the need for fixed anchoring.
The pipe system must be anchored and guided.
Absorbs small lateral movements along any plane.
Absorbs angular movements along a plane, when designed with two control rods.
By installing the control rods, the capacity to absorb axial movements is lost.
