hi to all,

At present i am doing one of my high pressure pipe line. it have 7500 psi.for reducing vibration and maintain a pressure we r introducing one dampener for discharge side.

i do not know how can i consider dampener suction and discharge side.

thanking You.


If i am asking wrong please correct me.

Please Expert give me some suggestion?

Get some help from a qualified engineer.

So, you are referring to a damper used to knock out pressure spikes on the dicsharge side rather than a structural damper used to reduce pipe velocity caused by this pressure pulsation.
Structurally speaking, your damper (bottle) is just a stiffness and mass which can be modeled as a few extra pipes, rigid elements and restraints.
Nice graphic.

thanks Dave and MoverZ.

so can i fix ANC for inlet and exhaust nozzle side. and then can i introduce zero rigid weight for in between nozzle connections.

is it correct Dave Diehl.

It looks to me the pump is reciprocating mud pump. Have you read the pulsation report. They must have listed the unbalanced forces in different zones.

I cannot comment on the detail or quality of your model.
You mention anchors at both nozzle connections with a weightless rigid element between them to represent the pump. No, these anchors will isolate the pipe from the pump. If you add temperature to that rigid element you will develop very large anchor loads. Perhaps a better model is to run rigid elements from each nozzle node to the pump base and anchor the base. These rigid elements can then grow to their hot position, displacing these nozzles. If you want to conveniently monitor nozzle loads, use anchors with Node/CNode pairs at the nozzles. I think of these anchors as "relative" anchors (Node/CNode) versus "absolute" anchors.

Thanks Dave diehl and PKU.

thanks for your valuable comments.
