  • System and method for protecting one or more pipes against corrosion and corrosion-protected pipe
    Patent number: 10718463
    Abstract: A carrier pipe is protected from corrosion by being received inside a casing at a location above ground. The casing, which can be formed from a polymer, defines a gap extending around an exterior surface of the carrier pipe. In one embodiment, the gap is substantially filled with a potting material having a corrosion-resistant property. In another embodiment, a self-contained impressed current cathodic protection system is received in the gap. A pull head is installed on the carrier pipe and/or casing for pulling the pipe assembly, including carrier pipe, casing, and elements received in the gap, into an underground bore as a single unit. In some embodiments multiple pipe assemblies are pulled together into the same bore.
