Axial Compression
Longitudinal movement shortens face-to-face dimension along axis of expansion joint or flexible coupling
Pipe flanges remain perpendicular to axis

Axial Elongation
Longitudinal movement lengthens face-to-face dimension along axis of expansion joint or flexible coupling
Pipe flanges remain perpendicular to axis

Torsional Movement
Rotation of one flange with stationary counterpart
Simultaneous rotation of both flanges in opposing Motion

Lateral/Transverse
Movement
Offset movement of one or both pipe flanges
Both flanges remain parallel to each other while forming angle to axis of joint


Angular Movement
Deflection or rotation of one or both flanges
Forms angle with axis of expansion joint or flexible Coupling

Vibration
Oscillating movement around axis of expansion joint or flexible coupling
Pipe flanges remain parallel with each other
Flanges remain perpendicular to axis
Mechanical vibration in steel piping system reduced with installation of pipe connectors or expansion joints
