Sacrificial Anodes on C/S Exchanger
Sacrificial Anodes on C/S Exchanger
(OP)
I generally see sacrificial anodes used in exchangers to protect against galvanic corrosion between two dissimilar metals. Are they ever used in 100% C/S construction? If not, why not? Is upgrading the metallurgy generally a better long term solution? The galvanic cell created to corrode the sacrificial anode should work the same as with two metals.

That doesn't mean there can't be other forms of corrosion occurring in an all CS exchanger, they just won't be galvani.

I wasn't concerned about galvanic corrosion in the all carbon steel construction, but rather, the use of sacrificial anodes to help it survive normal pitting corrosion from water.
EdStainless,
It makes sense that CS isn't the correct material of construction, but what is the disadvantage of using anodes besides inspection PMs?

And CP won't work where high velocities are an issues (HX tube entrance and exit).
