Instrument air copper piping - corroded
Instrument air copper piping - corroded
(OP)
The instrument piping is installed around cooling towers. It is copper and as you can see, it has a layer of green rust all over.
This installation is not older than 3 years.
What is the best way to protect this line? Paint? Wrap? Insulate?
Thanks

RE: Instrument air copper piping - corroded
What chloride level do you run in the cooling towers?
I suggest that you fabricate replacement lines, either in Cu or in 316 SS. And then paint them before installation.
Could you go to a high performance plastic for these lines? (remember to make sure that it is UV stable)

A good paint will protect your pipe.

This installation is not near the coast, but cooling towers environment is humid by nature.
If that is patina it should be protecting itself.
May be I should take one piece out and get a lab test...
