394 PRESSURE & DESIGN DATA Misalignment and Deflection
GRINNELL Flexible Couplings provide for restrained joints and allow for deflection to aid where the pipe or equipment is misaligned.
Note that flexible couplings will not accommodate both full maximum linear movement and the maximum available angular deflection concur- rently at the same joint.
