Line Vibration at 100bar

Dear Experts,
Please find the attached CII and Site vedio. The pump discharge line is vibrating heavily before 100bar.

the process parameters are as follows; Design press= 197bar, operating press= 172bar, ope temp = 150deg C.

kindly suggest to avoid the vibration. The model frequency matched to = 6hz, no FIV

Do it require damping type or special type supports?

The secondary steel portals which are exciting to be size to be modified?

Dear experts,

Continuation to the above post the pump is plunger type and used for flushing water with high pressure.

No FIV analysis performed earlier.

Request you all to support in rectifying the huge vibration problem.

You need a pulsation study. Work with the pump manufacturer.

Dan is correct. Usually the mitigation is either mechanical (e.g. adding restraints or stiffening existing supports) or acoustical (e.g. adding pulsation dampener, etc.). You can select whichever is practical and viable. You can also consult within your company if someone is specializing in this field. Maybe you have an in house fluid simulation software related to pulsation studies. Then you can exchange information, with you on the mechanical side.

Cheers!!
