-----Use of copper sulphate to protect metal
We inspect and repair oilfield tools i.e. threaded steel connections. I heard that after performing grinding to repair threads and shoulders of the oilfield connections (pin and box), we should apply copper sulphate ⇦ on eBay or Amazon [affil link] to the ground area. Can you explain the benefits and is it really worth it. The use a pipe dope to grease the connection prior to mating.

I rather doubt that you are using copper sulphate on oil well parts. It will promote rusting. You might be using a fine metallic copper based anti seize material or possibly copper plating.

Welding wire is frequently coated with a very fine layer of copper deposited by immersion in copper sulphate acid solutions to delay oxidation from air. It is not intended for top resistance, long durability or tough environments.
