Mechanical Snubber PSA 1, 3, 10

The Basic-PSA Mechanical Snubber is used to prevent shock forces from causing damaging motions in piping systems. The snubber controls such motion by becoming a load carrying member between the piping and structure the instant a force sufficient to cause abnormal motion is initiated. However, for normal thermal motion, the snubber telescopes freely in either direction through its operating stroke. The Basic-PSA Mechanical Snubber operates on the principle of limiting the acceleration of any pipe movement to a threshold level of .02 g’s. This is the maximum acceleration that the snubber will permit the piping to see. Should a disturbance attempt to accelerate the pipe in either direction, a braking force will be applied within the snubber of whatever magnitude required limiting the acceleration to a value less than .02 g’s. At the same time, thermal expansion, being a gradual movement, is not restricted. Basic-PSA, Inc.
