Use of Admiralty Brass - High Temp CW Service
Use of Admiralty Brass - High Temp CW Service
(OP)
Does anyone have information regarding the use of Admiralty Brass tubing bundles in cooling water service (tube side @ 100 deg F) and naphtha service (shell side @ 150-300 deg F)?
A history of failures, fouling concerns, etc. is what I'm interested in.
Thanks

Our problem is that someone decided about 20 years ago to replace existing Adm. bundles with carbon steel. This sacrificed a good life of 16+ years with a poor life of <7 years. And, this was replicated several times over that 20 year span.
Our CW system does have problems with flow, though I am unaware of the rate in this exchanger at this time. It's a systemwide problem that is being addressed over the next 18 months with upgrades.
My concern - being new to this field of corrosion - stems from a comment made by an "old timer" who seemed to remember problems with Adm. bundles at high temperatures. The only thing, I can't find any supporting evidence as such.
Thanks.

In my understanding, 150-300 degree F is not a high temperature service for admiralty brass.

I agree that Admiralty brass is better that CS for these
services
