What is a hydraulic snubber?

How can I test a snubber?

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.

How do I use a snubber?

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.

When should I install a piping snubber?

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.

What is a pipe snubber?

A pipesnubber is a device that permits pipe deflection under normal operatingconditions, but when subjected to an impulse load, such as an earthquake, waterhammer, etc., the snubber becomes activated and acts as a rigid restraint torestrict pipe movement as a result of the unwanted impulse loading.
