This expansion joint permits torsional rotation of connected pipes about their longitudinal axis. Rotation occurs when the applied torsion moment exceeds the friction moment. Typical configurations and application diagrams are shown below.
Retrieve expansion joint properties from the expansion joints database by clicking the "..." button and selecting the appropriate model.
