| MSA ¼ - MSA-100 MECHANICAL SNUBBER ASSEMBLIES |
| APPLICATION: |
The MSA series is a velocity limiting mechanical snubber
designed to protect critical plant components by preventing shock forces
from causing damaging motions in piping and related systems during
seismic disturbances or other transient forces. The mechanical snubber
controls damaging motions by becoming a load-carrying member between the
piping and the structural member in the event of an abnormal motion or
disturbance. Otherwise, during normal thermal motion and operation it
telescopes freely in either direction through its normal operating
stroke. |
