“Maximum Angular Deflection” may be called angular rotation. It is based on installation with no axial travel or lateral offset.
In addition to noise, vibration transmitted through piping can cause leaks, premature equipment wear and cracked welds. Expansion joints drastically reduce vibration transmission, thereby solving many of these issues.
“Maximum Axial Travel” may be called longitudinal movement or axial compression and extension. It is based on installation with no misalignment or angular deflection.
“Maximum Misalignment” may also be referred to as lateral offset or deflection. It is based on installation with no axial travel or angular deflection.
