Guidelines & methods required for Refinery piping vibration assessment

[Naren]

I have a an extensive task of assessing the severity of vibrating pipes in a refinery.<br>
<br>
I require practical guidelines & tools (software/ spread sheets, etc) to do this for the following areas.<br>
<br>
Quick screening methods. Risk classification?<br>
&quot;Shortcuts&quot; for natural frequency estimates, including lumped masses (valves, fittings, etc)<br>
Structural damping & frequeny calc's / guidelines.<br>
Allowable dynamic stress & amplitude calc's & limits.<br>
Velocity calc's & criteria.<br>
Small bore connection guidelines<br>
Practical support methods & spans<br>
etc,<br>
Thanks for your help in advance.<br>
<br>
Anybody with info. please e-mail me at:<br>

CadrePro is a good finite element progam for evaluating the vibration phenomena that you describe.&nbsp;&nbsp;The can be reached at <A HREF="
