Directional Movement for Fabric Expansion Joints
July 30th, 2012
Directional Movement for Fabric Expansion Joints
Axial Compression
The reduction in the breach opening along the axis of the duct. This is usually a result of thermal expansion of the ducting.
Axial Extension
The increase in the breach opening along the axis of the duct. In certain configurations, the duct thermal expansion may result in extension at the expansion joint location.
Lateral Movement
The relative movement of the upstream and downstream faces in the direction perpendicular to the axis of the duct.
Torsional Rotation
The twisting of one side of the duct about the longitudinal axis.
Angular Rotation
The twisting of one side of the duct about an axis perpendicular to the longitudinal axis.
