Baffle Design Methodology

11/28/2014 3:19 AM

Can anyone tell me how to calculate the thickness of a cirular baffe installed inside the Expander/Reducer at the outlet of the globe valve. The baffle is to be attached to the Expander by means of welding at the perifery of the baffle. Hope someone will tell me the methodology for designing the baffle..
Thanks in Advance...
Regards,Dinesh

We need a bit more information here:

Is this Baffle just a plain plate with a hole in the middle, as in an Orifice Plate, or is there more to it? What kind of valve is the Globe Valve? Is it a Regulator, or Stop Valve or otherwise? What pressures are involved?

First off all, i would like to thanks for your reply.

1. The valve type is Control Valve which is nothing but to regulate the flow or pressure of the fluid.

2. Baffle should have some hole pattern (depends upon CV) to reduce the Noise Level.

3. Regarding Pressure, It may change as per different specification. the high pressure rating of the valve is 20000psi (Choke Valve) which we need to calculate. but In My case, the Internal Pressure for four baffles are having 20bar,16bar,10bar,6bar respectively (Baffles Order from Valve Outlet (Expander inlet) to Expander Outlet.

Hope It will be useful... awaiting for your valuable replies... let me know if there any details need further...

Thanks in Advance...

By letting that out now and tagging it off-topic, I wonder what other information is being concealed. If you want timely help, Mildred, you need to be a bit more up-front with this stuff next time.

Baffle? Baffle? We don't need no stinking baffles!

Don't baffles create turbulence??

We don't need no stinking turbulence, either.
