Dynamic movement joint
Victaulic®’s Style W257 dynamic movement joint can accommodate differential settlement and seismic movement in large-diameter piping systems.Comprised of the Victaulic AGS™ Flexible Coupling Style W77, short pipe nipples and longer center pipe spool, the pre-assembled Style W257 joint reduces installation complexity. It is pre-engineered to determine the spatial requirements and number of coupling pairs needed. The joint requires no harness and arrives at the jobsite pre-grooved and assembled, ready for installation with only two grooved field-joint connections. Two couplings are self-aligning and provide a visual confirmation for proper assembly from metal-to-metal bolt-pad contact. The joint is available in 14 to 78-inch/DN350-DN1950 sizes and is compliant with AWWA M11.
