Design Parameters
Axial Compression
The dimensional shortening of the expansion joint face-to-face gap parallel to its longitudinal axis.
AXIAL EXTENSION (ELONGATION)
The dimensional lengthening of the expansion joint face-to-face gap parallel to its longitudinal axis.
Lateral
The dimensional displacement of the inlet and the outlet flanges of the expansion joint perpendicular to its longitudinal axis.
TORSIONAL ROTATION
The twisting of one end of the expansion joint with respect to the other end about its longitudinal axis.
Angular
That movement which occurs when one flange of the expansion joint is moved to an out-of-parallel position with the opposite flange.
