Electrically-conductive compositions and methods of using them with pipelines

Minimum Federal Safety Standards for corrosion control on buried oil and natural gas pipelines stipulate that metallic pipes should be properly coated and have impressed-current cathodic protection (ICCP) systems in place to control the electrical potential field around susceptible pipes. In certain examples described herein, electrically-conductive nanocomposites can be used and provide intrinsically-safe foam materials without the dielectric shielding issues of existing materials used to physically protect and stabilize buried pipelines. As cured or formed by customary spray applications, the nanocomposite foams described herein are directly compatible with ICCP functionality wherever foam contacts the metallic pipe. Various foam compositions and their use with underground pipelines are described.
