    Universal Expansion Joint with Overall Tie Rods is one consisting of two bellows connected(joined) by a common connector or centre piece for the purpose of absorbing any combination of the three basic movements: axial compression and extension; lateral movements; angular deflection. Universal Expansion Joint are usually furnished with control rods to distribute the movement between the two bellows of the expansion joint and stabilize the common connector. The definition does not imply that only a universal expansion joint can absorb combined movement. Double expansion joint is different from Universal expansion joint.
   A universal
expansion joint can be designed to have a very low lateral spring
force to minimize forces on adjacent equipment. A two tie rod
design can also accept angular deflection in a single plane. The
tie rods are usually at or near ambient temperatures and,
therefore, do not expand and contract as a function of the
temperature of the media within the pipe. As a result, the thermal
expansion of the length of pipe between the tie rod end plates is
forced into the bellows as an axial movement. The bellows design
must accommodate this axial thermal expansion as well as the
specified lateral movement. Sometimes a universal expansion joint
has a very heavy centre spool that can exert excessive weight on
the bellows elements. To protect the bellows elements from
excessive lateral loads, a support system such as a slotted hinge
can be installed across the individual bellows elements to support
the dead weight of the centre spool.
Advantages:
1.Simple and robust construction.
2.Absorbs large amount of lateral, angular and axial
movements..
3.Inexpensive.
4.Easy to install
5.Low maintenance
b)Disadvantage
-The changed flow direction
