In the process plant, random vibration with shell mode excited by the turbulence generated at tee connection might cause problems such as piping damage. Author proposed a new evaluation index in the previous work to evaluate the random vibration with

In the process plant, random vibration excited by the turbulence generated at tee connection might cause problem such as piping damage. In general, the beam mode piping vibration is known to be excited when the internal flow of the piping is the seve

Tests were performed on a mockup of a typical relief/blowdown system. The system consisted of an NPS6x8 pressure relief valve, an NPS12 tailpipe, and an NPS20 header. Small bore connections were installed in the tailpipe and header. Simple structures

During testing to support a program to improve acoustic induced vibration (AIV) assessments, it became clear that flow induced vibration (FIV) is excited at the same time; both mechanisms excite the shell flexural modes of the piping system, although

The calculation of acoustic induced vibration (AIV) for piping downstream of a valve is a critical step in predicting the damage from extreme levels of noise generated by pressure relief valves in flare systems. Three noise prediction schemes are con

Flow-Induced Vibration (FIV) caused by turbulent flow inside a pipe could lead to fatigue failure through shell mode vibration. Our previous study investigated the excitation source of the FIV for tee junctions experimentally to understand the FIV me

A consortium of companies is collaborating in a Joint Industry Project (JIP) for Acoustic Induced Vibration (AIV). Laboratory testing is one of the work areas of the JIP. The goals of the tests are to evaluate typical pipe fittings for AIV induced fa

In the flare piping system, it is known that piping vibrations occur caused by Acoustically Induced Vibration (AIV) and Flow Induced Vibration (FIV) corresponding to high flow rate, high pressure drop and relatively thin pipe wall thickness. For FIV,
