Mixing galvanized and black iron pipes within the same system can present several challenges. One of the primary concerns is galvanic corrosion, a phenomenon that occurs when two dissimilar metals come into electrical contact in the presence of an electrolyte, such as water. In this scenario, the zinc coating of the galvanized pipe can corrode at an accelerated rate due to the electrical activity created by the differing materials. As a result, the lifespan of the system may be significantly reduced, leading to potential failures and costly repairs.

Once the wire is drawn, it undergoes cleaning to remove any impurities or oxidation that may have occurred during the drawing process. After cleaning, the wire is then subjected to the galvanization process, where it is coated with zinc. Factories ensure that the coating adheres properly, providing excellent corrosion resistance.
