This table displays linear and rotational expansion joint deformation as projections on coordinate axes. Linear deformation is mutual pipe end displacement, while rotational deformation is mutual rotation of pipe ends. Deformation sign depends on the direction of local axes of elements adjoining the expansion joint.
For universal expansion joints the relative displacements of flexible joint (deformations) are checked using the following summary equation:
If allowable torsion rotation available, then 4th member is added to the equation above
For axial expansion joint the summary calculated as equivalent axial deformation x divided by allowable axial deformation xa:
Lb – Corrugated length of bellows
Lu – Distance between outermost ends of convolutions
Dm – Mean diameter of bellows convolutions
For single use compensators, deformation values for the welding moment are displayed (at welding temperature input in Project Settings).
Table view and contents depend on two properties, which must be input:
