: Covers terminology, acoustic and mechanical modeling techniques, and the physics of pulsation and vibration. Part 2: Specific Applications
The standard adopts vibration velocity limits (RMS) measured on pump manifolds, piping supports, and pulsation bottles. For example, steady-state vibration on discharge piping should generally remain below 25 mm/s RMS. Higher limits may be allowed for short-duration transient events. api 688 pdf
, officially titled "Pulsation and Vibration Control in Positive Displacement Machinery – Reciprocating Compressors Systems," is a definitive guideline published by the American Petroleum Institute (API). It establishes minimum requirements for the analysis, measurement, and control of pulsation-induced vibrations in reciprocating compressor systems. Higher limits may be allowed for short-duration transient
The standard applies to used in hydraulic fracturing services. Key systems within scope include: The standard applies to used in hydraulic fracturing
. Published by the American Petroleum Institute, it provides essential guidelines for managing the high-pressure pulses and mechanical vibrations that can otherwise lead to equipment fatigue, structural damage, or system failure. Southwest Research Institute Overview of API 688
