Abstract: A method of manufacturing a jacketed metal line is detailed herein. The method of manufacturing a jacketed metal line can include roughening an outer surface of a metal core of the line. An insulating polymer layer can be applied to the metal core, and the insulating polymer layer can include a reinforcing additive comprising: graphite, carbon, glass, aramid, short-fiber filled PolyEtherEtherKetone, mircron-sized polytetrafluoroethylene, or combinations thereof. The roughened metal core can then be exposed a heat source for at least partially melting the polymer layer; and the partially melted polymer layer and insulated roughened metal core can be ran through a set of shaping rollers.
