Snubbers, Sway Braces & Sway Struts
Snubbers and Sway Braces allow pipe movement in either a tension mode or a compression mode under normal operating conditions of our piping system. When an impulse even occurs, snubber devices act as a restraint, and when the event (such as an earthquake) dissipates, the shock control devices go back to their passive mode, and allow the piping system to move as normal. Sway braces use springs to provide a restraint force and allow movement during tension or compression in the pipeline. A stronger spring produces a stronger restraint forces and, unlike the snubber, the sway brace is always activated. Sway struts, while sometimes attached to sway braces, are intended to be a rigid support: where they do not allow for any deflection in either a tension or a compression mode.
