Mechanical Snubbers

Mechanical snubbers permit gradual thermal movements of the piping or equipment to take place virtually unrestricted. However, when a sudden dynamic event attempts to displace the piping or equipment, this dynamic restraint instantly provides a damping force proportional to the magnitude of the disturbance.

The Fronek A/DE DynA/Damp mechanical snubber’s principle of operation is simple and straightforward. When a dynamic disturbance attempts to displace piping or equipment in either direction, an oscilatory type escapement mechanism restricts pipe movement to a constant velocity. The DynA/Damp dynamic restraint has all of the advantages of hydraulic dampening without any of the drawbacks – it is a non-locking, velocity limiting device, that is always engaged and responds to dynamic disturbances instantly.
