ABSTRACT:
Combined strengthening and corrosion protection of a ferrous metal pipeline is obtained by means of a wrap of ferrous metal strip, the strip being coated with a less noble metal, such as zinc or aluminum or a zinc alloy or an aluminum alloy, and the strip being under sufficient tension to strengthen and reinforce the pipe or to arrest fracture propagation. The less noble metal coating of the strip is electrically connected to the pipe to provide cathodic protection for the pipe. A coating of electrically insulating material may be interposed between the pipe and the wrap. An external power source may be utilized for primary cathodic protection in which case the coated strip is relied upon as a secondary or back-up system.
