Vibration criteria for piping 1

[amadoc]

Hi everybody
I'm looking for some criterias for allowable vibration level in piping conveying gas or oil. I don't know what there is exactly in API and ASME standards (just abstracts...).
looking for your help
regards,

I have found some interesting information (formulas, examples...) in this document. This is a general document about liquid process piping.

The best available standard in my opinion is ASME OM-3, the title of which is something like Preoperational Vibration Testing of Class 1 Nuclear Power Plant Piping. It gives a screening limit for velocity (0.5 inch/sec peak), an endurance limit, and displacement limits, and more rigorous velocity limits based on system specifics. Note that the upcoming 2004 edition of ASME B31.3 includes an endurance limit f factor of 0.15.

thanks bvi (Mechanical),
your information is helpfull, that's exactly what i'm waiting for (and for others standards,i.e. api 14e and iso 13703)
best regards

I heard about it but no way for the moment to know what kind of rules there's in before buying it (195£...)
