allowable level of piping vibration
allowable level of piping vibration
(OP)
Does It exist a simple way to find allowable level of vibration for gas piping systems with reciprocating compressors? Where should I look for any information?

RE: allowable level of piping vibration
Have a look in API 618 it covers allowable vibrations for reciprocating compressor pipework.
RE: allowable level of piping vibration
Engineering Tool for this type is Analysis:
have a complete piping stress analysis CEASEAR II and or equal. Export in to FLUID analysis using: (BOS FLUID API 618, by Paluin Research group www.paulin.com.
BOS FLUIDS - Steady State and Transient Fluid Simulator API 618 APP. M & N. www.thill.biz
RE: allowable level of piping vibration
Another approach, in the 2004 edition of ASME B31.3, an "endurance limit" f factor of 0.15 is provided. So if the displacement stress range is less than 0.15[1.25(Sc + Sh) - SL], the system is considered good for an unlimited number of cycles.
RE: allowable level of piping vibration
Is the latest edition of B31.3 out yet? How can it be designated 2004 Edition when it's published in 2005. Seems silly to me.
