Piping Technology & Products supplied these mechanical snubbers with two end brackets, fabricated from carbon steel with an HDG finish for a refinery in Oklahoma. They are size MSA-10, 36″ OAL, and 30 1/2″ pin-to-pin. The snubbers are designed for an operating load of 15,000 lbs and have a 6″ maximum stroke. Standard load tests were performed prior to shipment. Mechanical snubbers have two modes of operation. In passive mode, i.e., motion caused by thermal loads, the resisting mechanism is disengaged and the snubber “free wheels” with very low resistance. In active mode the mechanism is engaged, and the snubber limits the acceleration to a low threshold value.
