5 Main Expansion Joints include:

1. Simple Expansion Joint – used to absorb a small amount of movements.
2. Universal Expansion Joint – used to absorb a combination of movements in a piping system that are too much for a single axial expansion joint.
3. Pressure Balanced Expansion Joint – versatile expansion joint is made for a combination of forces. The flow and balancing bellow produce equal but opposite forces under the same pressure, this cancels out the forces from multiple directions.
4. Hinged Expansion Joint – set in sets of two or three, absorb movement in one or more directions. It’s made to experience a strong axial pressure thrust and deflect the motion.
5. Gimbal Expansion Joint – similar to hinge expansion joints it uses its hinges to absorb rotation from any plane.
