Issues encountered in FIV calculations
Thread Content
In the FIV calculation, it is necessary to compute LOF (likelihood of failure); first, Fv needs to be calculated. This Fv = α(Dext/T)β is related to the natural frequency of the pipeline, but it’s not clear where one can find this value See the figure. It is necessary to find the two letters (α and β) in the diagram
FIV is generally based on the design in the EI rules, and this book provides a detailed explanation of each parameter. See the table below. I have also been studying FIV and AIV recently; we can exchange more ideas. If it’s convenient, you can add me on QQ: 404894401 and WeChat: 13523030351
May I ask what books provide detailed explanations on the calculation of FIV? I would like to ask at what flow rate and liquid volume will a 6-inch pipe experience flow-induced vibration?
Preliminary screening can be conducted using ρv2; if this value is greater than 5000 (with Shell specifying 10000), further screening is required. If it is less than this value, no further screening is needed.
Hello, do you have any rules regarding shells? If it’s convenient, could you send me one for me to study? Thank you
