Metallic pressure balanced expansion joint specifically designed to absorb axial and lateral movements while eliminates pressure thrust by means of force balancing design principle in the shortest possible length.
It’s designed to apply minimum forces onto connecting, load sensitive equipment.
The purpose of this type of expansion joint is to support and balance the force of the pressure, in a manner such that fixed anchoring is not necessary in the pipe system, and so that the forces and movements exerted on the flanges with the delicate equipment connected are reduced to tolerable levels.
Characteristics and Properties
This design needs more space to balance the forces.
It’s alowed to absorb lateral and axial movements, or combination of both.
Piping sustems wont rquired fixed points as the forces are balanced, and reduce the guide points.
minimum forces onto connecting, load sensitive equipment.
They are mainly used when space is restricted and the movements to absorb require more length on other pressure balance types.
