Hello Stressers!!!

Is it possible to use snubber to suppress vibration in a two phase flow line. Are there restrictions?. Basically, the temperature is high, so I need flexibility at the same time rigidity to solve both issues without re-routing the line.

Yes,Snubbers can be employed in such cases.
Carpenter and Patersons have special series (“200 Series”) of snubbers which suppress sudden shocks and dampen vibration also, while allowing simultaneous unrestricted thermal pipe movements.
Snubbers are dynamic restraints usually employed in the piping system to protect piping and components against sudden shocks, while allowing simultaneous unrestricted thermal pipe movements.
When subjected to sudden movements or shocks which exceed designated velocity limits the snubbers "locks up" momentarily and forms a rigid connection.

I don't use snubbers very much, but I seem to recall reading that snubbers may be no good for low frequency vibrations. Not sure how low is too low.

I guess the snubber can prohibit the effect from slug force, but prevent vibration? I'm not sure..

MK, you are correct. All snubbers can not dampen low frequency vibrations but "series 200" Snubbers by C&P are specially designed for this purpose. You can contact C&P vendor and get more information.Simillar design may be available with other vendors also.

Thanks all for the info.

I beg to differ on usage of snubbers for vibrations especially low frequency vibrations.

Either use dampeners or sway braces.

Sway brace would be right choice. line temp, pressure, application ,elevation, material, rating need to be consider before usage of any dynamic restraints.
