Pipe Support for Compressor (Centrifugal)
Pipe Support for Compressor (Centrifugal)
(OP)
Good Day!
I just want to ask regarding the support conditioning for the pipes connected to the compressor (centrifugal).
Is it advisable to attach the first support (from the nozzle) (a) to the compressor casing OR (b)to the structure?
I am afraid of the frequency issue because of the rotating equipment. Please give me some advice. Thank you in advance.

RE: Pipe Support for Compressor (Centrifugal)
Personally I have never seen piping supported from the compressor casing.

Pipes attached to any rotating equipment should be "neutrally mounted" with as little forces transmitted to the nozzle at rest and at operation. The pipe supports should be external to the machine structurally, mounted ultimately to a foundation common to the pump/compressor if vibration of either is controlled, or separately if vibration must be isolated.

API 617 is relevant to centrifugal compressor installations generally. The best source of information and analysis methods for vibration (vis-à-vis Piping) that I am aware of is the from the UK Energy Institute:
"Guidelines for the Avoidance of Vibration Induced Fatigue in Process Pipework" 2nd Ed.
