From where could i get the piping vibration acceptance limit ?
From your local Code-of-Practice.
Yes, barring any company/jurisdictional requirements - the best reference is:
ASME OM-S/G-2007, particularly Part 3 Requirements for Preoperational and Initial Start-Up Vibration Testing of Nuclear Power Plant Piping Systems
