Pipe natural frequency of 4 Hz.
Pipe natural frequency of 4 Hz.
(OP)
I have come across many projects where a piping system carrying two phase fluid is to be designed to have a natural frequency of 4 Hz or more.
My question is from where do we arrive at the figure of 4 Hz ? How does a natural frequency of piping system more than this figure ensure that the pipe is safe from vibrations ?

Such a value could not be used with larger bore refinery pipework without excessive restraint.
