This expansion joint allows torsion rotation of two connected pipes around their axis. Pipes will rotate around each other axis if torsion moment will be greater than friction moment. Typical drawing and application schemes are shown below.
All expansion joint properties can be taken from expansion joints database by pressing the "..." button and selecting the appropriate expansion joint.
Expansion Joint analysis results can be found in Expansion Joint Deformation Table. See also "How to Reduce the Nozzle Loads in START-PROF"
