api 617 vibration limits

[liamlucas]

hi
In this api the the vibration limits are not clear for axial , radial torsional can anyone help , any pdf file that explains it clearly ?

thanks

The following info. copy and paste from the web https://pipingandinterface.com/api-617-importance-applications/​

​

Radial Vibration:​

For general-purpose compressors, API 617 typically recommends a maximum allowable radial vibration limit of 0.1 mils (0.00254 mm) peak-to-peak at the bearing housing or compressor casing. For critical machinery applications, such as those involving high-speed compressors or machinery operating in sensitive environments, more stringent vibration limits may be specified.

Axial Vibration:​

API 617 typically sets a maximum allowable axial vibration limit of 0.2 mils (0.00508 mm) peak-to-peak at the bearing housing or compressor casing.

Torsional Vibration:​

Torsional vibration limits are also addressed in API 617, especially for geared compressors where torsional vibrations can affect the integrity of the gearbox and other components. However, specific limits may vary based on the compressor’s design and operating conditions.
