Apr 09, 2014The corrosion of steel piping and its related components is a continuous and virtually unstoppable process. The end product, which is commonly referred to as rust, is simply the result of an electrochemical reaction through which the higher energy-processed metal is slowly reverted back to its naturally occurring form metal ore.
