EXTERNALLY PRESSURIZED EXPANSION JOINTS

Externally pressure expansion joints are designed if there are large axial deflections and high pressures.Standart expansion joints under such conditions are subjected to ”squirming”instability.By applying external pressure the bellows becomes stable,it changes from a bellows in compression subject to buckling to a belllows in tension.

 

 

 

DIMENSIONS

The externally pressurised expansion joints are customised solutions and are available in all dimensions, all sizes
and all materials.
