Eccentric Reducer by Service

Eccentric Reducer by Service

Eccentric Reducer by Service

(OP)
Good morning,

In doing my research, I have seen that although the preferred orientation of eccentric reducers is FOT for pump suction piping, in applications that handle slurry service, the preferred orientation is FOB to avoid slug flow. Steam service was another that I saw with preferred orientation FOB.

My question is, are there any other applications or services where the eccentric reducer would be preferred with FOB in pump or compressor suction piping?

Thanks,
DGrayPPD

RE: Eccentric Reducer by Service

Good question. I think it boils down to where does one NOT want to accumulate vapor (FOT) or liquids/solids (FOB). I have not seen a complete itemized list for this and have just used my noodle on a case-by-case basis, but a list would be helpful.

Good luck,
Latexman

DGrayPPD, Good Post.
Latexman, Good response.
My contribution is very simple:
- FOT ECC Reducer:
Any Liquid Services subject to Vaporization (Hydrocarbons, Cooling Water, etc)

- FOB ECC Reducer:
Any Vapor Services subject to Condensing (Steam, LNG, etc)
Any Slurry services

Sometimes its possible to do all the right things and still get bad results

Thank you Latexman & Pennpiper. That confirms my thinking on the matter.
