Metal Expansion Joint
Silverfox can custom design and supply various types of expansion joints based on
your needs and requirements of the system. Some commonly used expansion joints are:
Universal Expansion Joint
Universal expansion joints are used where axial movement is larger than can be absorbed by a single
expansion joint. The universal expansion joint assembly consists of two single expansion bellows
connected by intermediate pipe. Universal expansion joints can also be used used where large amount
of movement in any combination (axial, lateral and angular rotation) is required which cannot be absorbed by a
single expansion joint.
Pressure Balanced Expansion Joint
Elbow Pressure Balanced expansion joints are designed to absorb axial and /or lateral deflection
while continuously restraining the pressure force. Balance (out of line) bellows creates an equal
and opposite force to the working (in line) bellows The typical arrangement as shown is to have a
balance side and a working side separated by an elbowed mid-section. Tie rods are used to
balance and restrain pressure forces.
