Screening Piping Vibration Problems

Piping Vibration Analysis & Integrity Assessment ...

Piping vibration analysis per EI 2008 Guidelines for the avoidance of vibration-induced fatigue failure (AVIFF). Piping systems are subject to vibration-induced failures. To mitigate this integrity risk, a piping vibration assessment is conducted during the design phase and high-risk locations are tested during the operations phase.

Common Causes and Effects of Piping Vibration – What Is ...

Piping Vibration can be defined as a continuous to and fro motion from an equilibrium position. Piping vibration problems cause serious integrity risks to operating plants; both onshore and offshore production facilities. The vibration of the Piping System can cause fatigue failure on process piping and small branch connections and reliability problems on equipment.

Causes, assessment and reduction of piping vibrations

In general, the measurement of piping vibrations is not a problem. However, the assessment of the measured values is difficult. Standards and directives as known for example from the field of machine vibrations (VDI 2056 [1], DIN ISO 10816 [2]), are non-existent for the assessment of piping vibrations.

VIBRATION ASSESSMENT METHOD AND ENGINEERING …

4 C5 = the correction factor to account for off-resonance forced vibration; α = the allowable stress reduction factor, 1.3 for carbon steel and low alloy steel and 1.0 for non- corrosive steel. Conservative values were used for the correction factors to derive a screening peak velocity of max Vscreen =12.7mm/s (0.5in./s) applicable to most piping configurations in appendix D. Piping
