Copper pipe electrolysis from touching steel

Copper pipe electrolysis from touching galvanized steel 2003. A. Copper pipes can corrode in at least three different ways, but the differences are quite technical. I would suggest that the corrosion could be induced by a galvanic couple caused by contact with the galvanised pipe and this results in an induced local anodic polarisation of the copper pipe.
