Did You Know?

Galvanized piping is NOT the answer to controlling internal pipe corrosion! Zinc (the metal used for galvanizing) corrodes inside a pipe the same way that bare steel does. In fact, breaching of the galvanized coating concentrates the corrosion reaction at one point, rapidly causing pits and pinholes. Galvanizing of pipes is ONLY intended to help with the external appearance of pipes. Don’t count on galvanizing – take positive steps to prevent internal corrosion such as NITROGEN-PAC.
