Pipe snubber including reservoir and seal structure |
摘要 |
A pipe hanger/snubber for supporting and/or protecting high-pressure piping and the like against damage by seismic, vibrational, and thermal shocks to the mechanical integrity of the piping system. The apparatus includes a sealed snubber cylinder containing a non-Newtonian fluid as the hydraulic fluid medium. A working shaft extends completely through the snubber cylinder. A shaft-mounted, perforate load nozzle is moved longitudinally through the non-Newtonian fluid in the snubber cylinder to thereby dissipate the shock forces. Shaft-engaging seals at each end of the snubber cylinder inhibit leakage of the non-Newtonian fluid from the snubber cylinder. Selectively, reservoir apparatus containing non-Newtonian fluid are provided adjacent at least one seal to compensate for leakage, if any, of the non-Newtonian fluid through the seal. The reservoir apparatus are provided with leakproof closures and, selectively, compression/expansion apparatus to compensate for volume changes imposed on the non-Newtonian fluid in the reservoir apparatus.
