You Don't .. You replace them
galvanized iron pipes commonly used on water pipe lines, it is dipped into zinc for corrosion protection
I would use hot water conn. on it. Both on cold and hot
GI Pipe is "Galvanized Iron" Pipe. These days the pipe will likely be made from steel rather than iron.
Galvanized pipe will be silver/gray color. Copper will be copper. Use a magnet, it'll stick to galvanized pipe but not to copper. Drinking water lines should not be black steel pipe.
Galvanized pipe is used for natural gas lines and pressure vent lines, and for electrical conduits. As a water supply or drain pipe, it is subject to rusting over time.
For cold water,start at the water meter, the follow it to the hot water tank for the hot lines. They are pretty easy to see, they are either copper or pex, or galvanized pipe.
Hot-dip galvanized pipe is made by reacting the iron substrate with molten metal to form an alloy layer, thus combining the substrate with the coating. Hot-dip galvanizing requires pickling of the steel pipe to remove iron oxide from the surface of the pipe. After pickling, it is washed in an aqueous solution of zinc chloride or ammonium chloride or a mixture of ammonium chloride and zinc chloride and then sent to a hot dip galvanizing bath. Hot dip galvanizing has the advantages of strong adhesion, uniform coating and long service life. Cold galvanizing is what we call electro-galvanizing. The amount of galvanization is very small, and the corrosion resistance of cold galvanized pipe itself is very different from that of hot galvanized pipe, so many construction projects do not use cold galvanized pipe. At present, the Ministry of Construction has officially stated that technically backward cold galvanized pipes need to be eliminated, and cold galvanized pipes will not be allowed to be used as water and gas pipes in the future. Shanghai Changzheng's cold rolled steel sheets are of superior quality and are the choice of most people. Buy steel plates from Shanghai Changzheng.
Depends on local codes and the PH of the water
Yes.
There are no hoses that do this. There is only copper pipe, galvanized pipe, or PVC normally use in a home water supply.
ya the galvanized pipecan be use in undergrounds,,, because it is an iron pipe
Water does, so I am pretty sure steam will
