Mechanical Snubbers For A Refinery In Oklahoma

Type: Mechanical Snubbers
Size: Size MSA-10, 36″ OAL, and 30 1/2″ Pin-To-Pin
Material: Carbon Steel with HDG Finish
Design: Operating load of 15,000 lbs and a 6″ Maximum Stroke
Testing: Standard Load Tests

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 before 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. The mechanism is engaged in active mode, and the snubber limits the acceleration of motion to a low threshold value.

In addition to refineries, mechanical snubbers are preferred for use in nuclear plants as they do not contain hydraulic fluids that could degrade over time. Mechanical snubbers are also used in chemical, power, and green energy plants such as solar and geothermal. Mechanical snubbers are also used in earthquake zones to limit shock or sway caused by seismic disturbances.
