On new installations of ductile iron pipe, Polywrap from AA Thread Seal Tape is good insurance to protect your project. Polywrap is an easy-to-install polyethylene encasement sleeve that is pulled over the pipe at time of installation. This is an economical and effective way to protect ductile iron pipe from exterior corrosion. There are many types of polywrap, but 8-mil, linear low-density is the most common. While it is typically black, other colors are available to mark what the pipe is being used for.
