Connecting different metals together electrically for grounding purposes often results in corrosion problems on buried piping systems. The corrosion is caused by direct current flowing between dissimilar metals. When establishing grounded systems to protect persons and equipment, it is necessary to consider the means of minimizing corrosion of metals buried in the earth.
