MSA 1/4 – 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.
How To Order: Please specify figure no., cylinder size, stroke, load, cold and hot piston settings, and piston end option. If clamp is required, please specify nominal pipe size, or special O.D. and clamp material. Please specify or describe any additional optional features or special settings required.
