A hydraulic snubber is a device that permits pipe deflection under normal operating conditions, but when subjected to an impulse load, such as an earthquake, water hammer, etc., the snubber becomes activated and acts as a rigid restraint torestrict pipe movement as a result of the unwanted impulse loading.
A hydraulic snubber includes a hydraulic fluid reservoir and cylinder to produce the restraint force when activated.

Field testing of snubbers is not recommended. In order to accurately confirm the function of a snubber, a certified test machine must be utilized to accurately simulate impulse loading.

The main criteria to remember when utilizing snubbers is that they are intended to be passive elements during normal operation and will become activated only when that unwanted impulse event is present. When that impulse event dissipates, the snubber will become deactivated and thus produce negligible restraint to pipe deflections under standard operating conditions.

Because snubbers are not meant to be active support components, they could be installedat any time during the construction phase. It should also be noted that pipingsnubbers can be retrofit to existing systems at any time.

This Webinar will focus on the different types of variable spring supports and big ton variable spring supports. Learn about the special features available, in addition to the design of a variable support. View how the different coil configurations produce a unique response to an applied load and see how a spring assembly is loaded. Discover the basic steps in selecting a hanger design and the step-by-step process used to size a spring for your application. Learn about the different attachments, testing, and installation and maintenance procedures. View examples of failed supports provided by our Field Service Division and learn why they failed and how to prevent it. Gain knowledge of the valuable tips used when deciding to replace or re-calibrate a variable spring support, as well as adjustments, shutdown, and isolation procedures.
