How do you remove corrosion from copper pipe?

Answer 1

First the pipe and cap must be dry. There can be no water the pipe that will be close enough to the joint to feel the heat.

You will need Soldering Flux, Solder, Emory Paper and a hot Torch. Turbo Torch is a good one, if you use MAPP Gas.

Sand the pipe with the Emory Cloth until it is clean and shiny all the way around. (The width of the cloth is fine.) Sand the Cap the same way. Put Flux on the copper pipe and inside the cap. Put the Cap on the pipe, push it all the way down.

Take the torch and heat the cap on it's side in one spot while holding the Solder on the opposite side at the point where the bottom of the cap and the pipe meet. When the joint is hot enough the solder will melt and start to draw into the joint. After a few more seconds remove the heat and melt solder all the way around the joint in one quick motion. You can wipe the joint with a rag if you like to make it look better before the solder hardens. Don't use Nylon or any other cloth that might melt.

Answer 2

You can remove corrosion from copper pipes by using a fine sandpaper or a wire brush to gently scrub the affected area. You can also create a paste using equal parts vinegar, salt, and flour, apply it to the corroded area, and let it sit for a few hours before wiping it off. After removing the corrosion, make sure to rinse the area thoroughly with water.

Answer 3

Corrosion implies that the material of the pipe has already been removed, if it continues the pipe will eventually disintegrate. Therefore you can not remove "corrosion", you can only replace the pipework with new copper.You can however add chemical to prevent corrosion from happening in the first place, ot stop its progress.

Answer 4

With a propane torch. Heat the cap and remove all the solder and pull off the cap.
